Win2PDF will support the new Windows 11 operating system

Microsoft announced details of its latest version of Windows operating system last week. Windows 11, as it will be called, will have some new features and interface changes, and will be a free update to existing Windows PCs. It will be available later this year.

Will Win2PDF support it?

Yes! Win2PDF will fully support Windows 11* when it is officially released. We intend to release Win2PDF on the same day that the Windows 11 software is made available.

* Just as with Windows 10, Win2PDF will only support Windows 11 with the Intel and AMD processors (which accounts for most PCs); it will not support Windows 11 on the Qualcomm (ARM) processors.

Will my current PC be able to run Windows 11?

Microsoft has an overview of how to find device specification requirements, versions, and languages available for Windows 11. They also have an app you can download to see if your existing PC will be capable of installing Windows 11.

Will there be a charge for the Windows 11 Win2PDF update?

No. It will be a free update to all Win2PDF 7 and later versions of Win2PDF.

If I get a new Windows 11 PC, will I be able to transfer my license to a brand new PC?

Yes. Just install Win2PDF on your new PC and use your existing license code to activate the software.

We’ll have further announcements prior to the release of both Windows 11 and Win2PDF later this year. If you have any questions in the meantime, just let us know.

Digital Signatures, Digital Certificates, and PDF Authentication

For centuries people used a wax seal on letters to prove to the recipient that the letter was from a trusted source and had not been tampered with.  Did you know there is a way to do this digitally with your PDF file?

We recently added a feature that allows you to apply a digital certificate to a PDF file when it is created by Win2PDF. The certificate — which can be created by you, or purchased from a certificate authority — allows the recipient to verify that the file was ‘signed’ from the sender and that it hasn’t been altered or modified.

Before we get into the specifics of this feature, we should probably do a little explanation of terms surrounding digital signatures and what is commonly known as “digitally signing” documents, because it can be a confusing topic.

There are several ways of doing this that largely break down into 2 categories.

  1. Electronic Signatures (or e-signatures):  This method of signing a PDF allows the user to apply a simple image representing a person’s handwritten signature.  It is simple and easy to implement, and is legally permissible for many types of documents, but also not very sophisticated.  For example, it would be easy for someone to scan a signature of someone else, and then use it to apply to PDF files without the signature owner ever even knowing about it.  Aside from the representation of the signature, there isn’t a formal way of authenticating the creator is who they say they are.
  1. Digital Signatures: This method of signing is more sophisticated and preferred by companies that require a greater level of source authentication.  With this type of digital signature, an encrypted certificate is embedded within the PDF file.  The recipient of the file can view the certificate and verify exactly “who” created it.  For example, if I create a trusted certificate as John Doe from Win2PDF Sales and applied it to a PDF file, the receiver of that file would be able to verify that “John Doe” really was the creator of the file and that the document hasn’t been modified since it was signed.  There are also different types of certificates that can be used, from simple digital IDs that you can create yourself in Adobe Reader, to more advanced ones that can be purchased and verified by an approved certificate authority (CA).

The new Win2PDF feature utilizes this second method — digital signature, or digitally signing documents using certificates.  It requires a valid Win2PDF Pro software license (request a trial version if you want to try this), and it assumes that you have already either created or obtained your own digital certificate.  Adobe’s web site provides documentation on how to create your own Digital ID in Adobe Reader.

Here is an overview of the steps needed to apply a digital certificate to a PDF file using Win2PDF:


  1. Download and install Win2PDF Pro 10.0.108 or later software. [Note: This links to the Win2PDF Pro Service Pack for the latest version.]
  1. Download and install the PDFSignWithCertificate Plug-In.
  1. Once these 2 components are installed, you will see a new checkbox on the Win2PDF file save window.  If this box is checked, you will get a pop-up to select a certificate when the PDF file is saved.

  1. When the PDF file is saved, choose your Digital Certificate.  If you used Adobe Reader to create your digital ID certificate, for example, the file would have a .pfx file extension and be located on your hard drive folder named:

C:\Users\[your username]\AppData\Roaming\Adobe\Acrobat\DC\Security


  1. When the Digital Signature file is applied, it will require you to enter in a password to complete the certificate application to the PDF file.  This password is something you set up when creating your Digital ID or obtained from a certificate authority.

  1. Lastly, when you open the PDF file in Adobe Reader, Adobe recognizes the PDF file as being signed with a valid digital certificate.  You can see how this is displayed in Adobe below.
  1. If you examine the certificate in the Adobe Reader software, it will show the details that were used. Here, the recipient could verify that the file was signed by John Doe from Win2PDF Sales. 


For advanced users, Win2PDF Pro also supports a command line to sign PDF files with a digital certificate.

This has just been an overview of the new Digital Signature feature in Win2PDF Pro.  If you have any questions please let us know and we’ll be glad to provide more assistance.

Video demonstrates PDF renaming using Win2PDF and Power Automate Desktop

As we continue to document Win2PDF and Microsoft Power Automate Desktop, we now have a short video tutorial that shows how to rename a folder of PDFs based on content found in each PDF file.

How to rename PDFs based on file contents

Give it a look. This may make it easier to get a basic understanding of how these two tools work together, and how you can take advantage of other automated PDF workflows.

Flattening a PDF file with Win2PDF

We recently stumbled across this article outlining a problem with 2020 tax returns saved as a PDF file.


Q: I’ve been using the free Adobe Acrobat Reader DC to fill-in and save PDF tax forms on my PC. But when I recently called up a stored tax form, the data I’d filled-in appeared for a moment, then disappeared, leaving just a blank tax form. I then called up other tax forms that I’d saved earlier, and found that they still had their data. I then tried using another PC, and found that some stored tax forms contained the data I’d entered, while others had gone blank. Adobe won’t help me with this problem because I’m using a free app. What’s wrong and what can I do?


In this case, there was a glitch in the PDF viewer where the filled-in data appeared to “go missing”, even though the information was saved in the file. This type of problem is caused by PDF layers, and it can be easily fixed by flattening the PDF file.

Basically, flattening the PDF means compressing all of the data onto a single layer. No data or information will appear to be missing — all of it will be visible at all times — so the problem experienced with the “missing data” in the tax forms will be eliminated.

While there are several ways to flatten a PDF file, one of the easiest is to just print the document from Adobe Reader (or any PDF viewer) to the Win2PDF printer using the PDF Image Only option. That will flatten it automatically.

After you print to Win2PDF, the resulting PDF will no longer be searchable. If you want the text in the flattened PDF to be searchable, you can download and install the “Win2PDF Desktop with OCR” add-on and select “Portable Document Format – Searchable” as the Win2PDF “Save As Type”.

Using Win2PDF & Microsoft’s Power Automate Desktop to Rename PDFs

Our last post — Get Into Your PDF Flow using Microsoft’s Power Automate Desktop Software — gave an overview of the Power Automate Desktop software and how it can be used to automate repetitive tasks with PDF files.

Over the next series of posts we’ll show some examples of how this can be done in a real-world context using Win2PDF.

First, let’s start off by using an example where we want to automatically rename a bunch of PDF invoices that are stored in a folder. And then suppose we not only want to rename the PDF files, but we want the new file names to be based on some content within the original files, such as the number following the word “INVOICE”.

In the following example (see Microsoft Power Automate for Desktop flow for renaming PDF based on File Contents for details), we’ll search through each PDF in the folder and rename the file based on an invoice number that follows the word “INVOICE”. Here’s what the desktop flow looks like:

Notice how the Win2PDF command line getcontentsearch feature is used. It allows us to search for the word “INVOICE” in the PDF file, and then return the following content (in this case, the INVOICE number) to the standard output. After trimming any extraneous spaces from this invoice number, the PDF file is renamed to be that invoice number.

You can use the graphical user interface to make your own flow, or you can copy the following into a new Power Automate Desktop flow if you want to use this as a starting point for your project:

# This flow searches the contents of PDF files in the selected folder for SearchText, and renames the PDF files based on the text immediately following SearchText.  Change the SearchText variable to the desired search field.  Note : the SearchText field is case sensitive.
SET SearchText TO $'''INVOICE :'''
Display.SelectFolder Description: $'''Select Folder to Rename''' IsTopMost: False SelectedFolder=> SelectedFolder ButtonPressed=> ButtonPressed3
Folder.GetFiles Folder: SelectedFolder FileFilter: $'''*.pdf''' IncludeSubfolders: False FailOnAccessDenied: True SortBy1: Folder.SortBy.NoSort SortDescending1: False SortBy2: Folder.SortBy.NoSort SortDescending2: False SortBy3: Folder.SortBy.NoSort SortDescending3: False Files=> Files
LOOP FOREACH CurrentItem IN Files
    # Search for %SearchText% field and return following text in CommandOutput using the following Win2PDF command line:
    # C:\Windows\System32\spool\drivers\x64\3\win2pdfd.exe getcontentsearch "%CurrentItem%" "" "%SearchText%"
    System.RunDOSCommand DOSCommandOrApplication: $'''C:\\Windows\\System32\\spool\\drivers\\x64\\3\\win2pdfd.exe getcontentsearch \"%CurrentItem%\" \"\" \"%SearchText%\"''' StandardOutput=> CommandOutput StandardError=> CommandErrorOutput ExitCode=> CommandExitCode
    IF CommandExitCode = 0 THEN
        Text.Trim Text: CommandOutput TrimOption: Text.TrimOption.Both TrimmedText=> TrimmedText
        File.Rename Files: CurrentItem NewName: $'''%SelectedFolder%\\%TrimmedText%''' KeepExtension: True IfFileExists: File.IfExists.Overwrite RenamedFiles=> RenamedFiles
    ELSE
        Display.ShowMessageWithTimeout Title: $'''Win2PDF Renamer''' Message: $'''Could not find \"INVOICE :\" field for file %CurrentItem%''' Icon: Display.Icon.None Buttons: Display.Buttons.OK DefaultButton: Display.DefaultButton.Button1 IsTopMost: False Timeout: 10 ButtonPressed=> ButtonPressed4
    END
END

This example shows one way to use Win2PDF’s automation features to create a solution unique to your workflow. It also uses features that were added in the latest Win2PDF 10.0.100 update, so make sure you are using the latest Win2PDF 10 Update when trying any of the Power Automate Desktop features.

Can you think of any similar cases that you might use? If so, drop us a line. We’ll have more examples coming soon.

Win2PDF 10 build 98 Update Now Available

The time honored tradition continues! Punxsutawney Phil saw his shadow, which means 6 more weeks of winter AND new Win2PDF 10 features to help you get through it!

The latest update to Win2PDF 10 (build 98) is now available on the official Win2PDF download page.

Some of the new features have been documented in previous blog posts, but now those features (and some others) have all been collected into a single update. This Win2PDF 10 (build 98) software is a free update to licensed Win2PDF 10 users.

The biggest changes are related to enhanced mail support for sending PDF documents, new command line options for converting and manipulating image and PDF files, and general bug fixes and stability improvements. Here’s a summary of the changes.


  • Added IMAGEPDF command line to convert a PDF file to a PDF Image Only (color or monochrome).
  • Added support for page range in PDF2TIFF command line.
  • Added a Send Mail feature to the Win2PDF Desktop App.
  • Added support for the PAGECOUNT command line option to return the number of pages in a PDF.

All of these features were added to the Win2PDF software based on customer feedback and feature requests.

Is there something you’d like to see in a future version of Win2PDF? If so, let us know. We’ve got another 6 weeks of winter to work through.

Enhanced Mail Support in Latest Win2PDF 10 Update

Win2PDF has always had the capability to attach a new PDF file to a mail message, though the implementation was limited to the default MAPI mail client on the computer (typically Outlook).

Many users have asked us to support other mail programs and services, like Gmail or Yahoo! Mail, to send files. Our latest 10.0.93 version of Win2PDF dramatically improves mail client support and allows for direct mail integrations with:

These mail programs can be set up using the new Configure Win2PDF Mail window, which can be accessed either from the Win2PDF Start menu program group (shown below):

[You can also use the Windows search box (the “magnifying glass” icon) and search for Configure Win2PDF Mail to open the configuration screen.]

Or, it can be accessed directly from the Win2PDF Desktop program, by going to File → Mail → Configure Mail (shown below):

Once the Configure Mail window is accessed you will have the following options to enter your mail settings:

To fill in the different mail settings, please see the individual support pages for Microsoft Outlook, Thunderbird, Gmail, Outlook.com, Yahoo! Mail, or Custom SMTP Server.

After the mail program settings have been configured, you can send a PDF file using one of these two methods:

  1. Select the Send file… option on the Win2PDF file save window (if you are creating a new PDF file with Win2PDF), or
  1. Open a PDF file in the Win2PDF Desktop app and choose File → Mail → Send Mail (if you are just sending an existing PDF file)

And that’s it. You can download the latest 10.0.93 software (a free update for existing Win2PDF 10 users) from our Win2PDF 10 Update page.

As always, if you have any questions, just send a mail to [email protected].

[Case Study] Converting TIFF to PDF Using New Command Line Tools

Win2PDF has expanded its Command Line Interface to support two new conversion features.

  1. TIFF to PDF — This option converts TIFF graphic images into PDF files.
  1. PDF Image Only — This option converts PDF files to an Image Only format. Image Only PDF files can be used to make the PDF unsearchable, “flatten” text fields for security, speed up loading time for complex PDFs, and reduce the PDF file size.

As an example, consider this example we recently solved for a customer. They wanted to merge a scanned TIFF image to an existing text-based PDF file.

To accomplish this, they created a small batch file. The first line of the batch file converted the TIFF file to a PDF.

Win2Pdfd.exe tiff2pdf "1.tif" "1.pdf"

The 2nd line merged the PDF into the existing text PDF. (where “2.pdf” was an existing searchable text-based PDF).

Win2Pdfd.exe append "1.pdf" "2.pdf" "New.pdf"

The 3rd line flattened the file to an Image Only PDF. This made the combined PDF file unsearchable.

Win2Pdfd.exe imagepdf "New.pdf" "NewImageOnly.pdf" mono

In terms of formatting for the batch file, full path names were used so that it looked like this when the batch file is run from the Windows command prompt:

They had been struggling to find a solution to do this one particular document conversion, and the batch file solution not only provided the final document with the formatting they needed, but also provided the flexibility to integrate this into their existing document management process.

As we expand the options available in the Win2PDF Command Line Interface, the ability to do these types of highly customized and automated solutions is becoming easier, especially when coupled with Win2PDF Plug-Ins.

As always, if you have a particular conversion or process need for your PDF files, let us know if we can help.

Win2PDF Plug-Ins Extend Features Specific to Customers’ Needs

Last month we introduced a new Win2PDF Plug-In for Slack, and this month we’re back with several new Win2PDF Plug-Ins.

A Win2PDF Plug-In is simply a small customizable program that can be created, modified, or installed that will give the user an option to automatically take some action with the PDF file after it has been created. It allows Win2PDF’s functionality to be extended to address specific customer needs or workflow integrations. For example, it has already been used by customers to upload PDF files to a content management system, automatically make archival copies of PDFs, store PDF in cloud-based services, delete blank pages, split PDF files into single page documents, use multiple watermarks, and send a PDF file to a specific email program.

Why use Plug-Ins? Why not just add these features directly to Win2PDF?

The Win2PDF Plug-Ins were created specifically to add capabilities that might be unique to each customer. Most of the new Plug-Ins were unique or very specific to a customer request, so they may not be useful to the user base at large. Rather than clutter the main Win2PDF program with these types of unique features, we allow them to be created, customized and added as needed for each customer.

As of today, there are 8 additional Plug-Ins available for download at our GitHub page. [GitHub is a central code repository for our Plug-In samples — you can download compiled Plug-Ins that are ready to use, or, if you are a developer, you can download and modify the source code to build your own Plug-Ins specific to your needs. These examples show what can be done with Win2PDF, and provide a template for future solutions.]

The new Plug-Ins are:

  • PDF Send To Outlook – Add a “Send To Outlook” option to Win2PDF File Save window to automatically attach a PDF to an Outlook email message.
  • PDF Duplicate File – Automatically make a duplicate copy of the newly created PDF file in a designated duplicate file folder which may reside on a shared network location or in a cloud based folder (OneDrive, DropBox, Google Drive).
  • PDF Print Logger – Automatically log files created by Win2PDF to the Windows Event Log.
  • PDF Archive File – Automatically archive newly created PDF files created by Win2PDF in a designated archive file folder which may reside on a shared network location or in a cloud based folder (OneDrive, DropBox, Google Drive). Files are appended to an archive PDF named based on the current date.
  • PDF Delete Pages – Automatically deletes extra pages from a newly created PDF.
  • PDF Split Pages – Automatically splits a multi-page PDF into separate one page PDFs.
  • PDF Apply Multiple Watermarks – Automatically apply different watermarks to separate sections of a PDF [Requires Win2PDF Pro].
  • PDF Image Only Flattener – Automatically merge watermark layers into a single layer Image Only PDF [Requires Win2PDF Pro].

A few other notes:

  • The samples only allow one Win2PDF Plug-In used for each instance of the Win2PDF printer.
  • If you wish to remove a particular Win2PDF Plug-In, you can use the Windows Add/Remove Programs feature to uninstall.
  • All of the Win2PDF Plug-Ins hosted on this page can be used at no charge. Some only work with licensed versions of Win2PDF. Contact [email protected] for a 30 day evaluation license.
  • An evaluation version of Win2PDF can be downloaded for free at https://www.win2pdf.com/download/

If you have any requests for Plug-Ins, let us know. We’re interested in building out this capability with more examples, so if you have a particular integration or special need, send an email to [email protected] and tell us about your requirements. If it’s something we can assist with, we’ll be happy to help.

For now, hop over to the Win2PDF Plug-Ins page and take a look.

It’s Greek To Me: Case Study for PDF Image Only Files

We recently received a unique support question that illustrated a real-world case where the PDF Image Only file save option saved the day. Here was the issue our customer came to us with:

I am trying to help my wife who is teaching ancient Greek language classes online. The problem is that there is no standard universally recognized font for ancient Greek – they all render the language in different ways. And ancient Greek is quite different from modern Greek. She can create documents on her Windows PC using one of a number of specialized TrueType (TTF) fonts. And she can convert documents to Unicode for pasting into web content and/or she can print or export Unicode documents to PDFs. For most of her students these processes are successful. However some students see only gibberish. She has no control over the various platforms her students are using, Windows, Mac OS, iOS, Android, Chrome, etc.

By Hesiod / Houghton Library, Public domain, via Wikimedia Commons

Is there a way Win2PDF can handle this situation? The best option would be if she could print/export her multi-page documents to non-searchable, graphics only PDFs.

For this case, the solution was easy. Win2PDF can create multi-page image only PDFs that render the TTF fonts as graphics. It’s just a standard Win2PDF file save type the user can select when printing.

While this particular customer was able to make the conversions using other programs, this was the easiest method since it was just a single step to save the PDF file.

When we recommended this solution to the customer, he gave us the following reply:

While the Covid-19 pandemic lasts and much teaching is being done online, you might want to share this information with university departments of Classics and Religious Studies and theological colleges (and other academic institutions that teach archaic languages for which there are no universally standard means of rendering them as computer-created text). My wife cannot be the only university instructor with this problem.

Consider it done.
