PDF-XChange Viewer supports all Windows (32/64 bit) operating systems from Windows XP** and later.

Version 5 (2012): Microsoft/Citrix Terminal Server compatible*.
Version 4: Microsoft/Citrix Terminal Server compatible*.
Version 3: Still available for Windows 95 and later.

* Note: Though many users have virtualized some of our component products such as the PDF-XChange Viewer and PDF-Tools application using XenApp, we do not support this at this time.
Particularly the printer drivers are not designed to work in a virtualized environment.

** Limitations to product support for Windows XP

To experience the best performance of our products on all Windows operating systems, the onus is on users to ensure that they have all the latest available Microsoft Windows Service Packs & Updates installed.

PDF-XChange Viewer 'Free Version' is free for private and commercial use, provided it is not bundled with other software for financial gain. The Viewer as well contains extra features and functions that are unlocked when you purchase a license for PDF-XChange Viewer PRO.   In FREE mode, many menu items will be marked with a special marker that indicates that the specific feature requires a PRO license to use without producing watermarks: PRO Function Logo

You can try any of the PRO features but, be very careful not to save your PDF if you don't want the watermarks to appear in the upper corners of each page of the document.  Once a document is watermarked, there is no way to remove them so save a copy of the original PDF before trying the PRO features in an unlicensed Viewer.




PDF-XChange Viewer Help Manual - To reduce the size of the Viewer installer download file the Help Manual is now a separate download.

You can download the Viewer Manual here: Download PDF-XChange Viewer Help Manual.

Please note :
The PDF-XChange Viewer is not designed to create new PDF files from 3rd party document formats such as MS Office, Internet Explorer etc - if you wish to create NEW PDF files from Windows applications (any that can print to paper)  then choose one of our Virtual Print drivers below - the PDF-XChange Viewer is designed to create PDF files only from images - or to scan new pages from your scanner - as well as View/Modify/Annotate etc - existing PDF files!

We recommend all users who need to ask which version to download - use the exe/zip installers (the only difference is one is wrapped in a zip file as some download management software will block '.exe' files) as this will correctly sense and install for the Windows version you use,  MSI installers do not and you must be sure you download the right version - for the operating system your system uses.  

Virtual Print Drivers

PDF-XChange 4 Lite (Now FREE for non-Commercial use, and included for commercial use with the purchase of PDF-XChange Viewer Pro)

PDF-XChange 4 Standard

PDF-XChange 4 PRO (includes PDF-XChange Viewer PRO)

MSI Installer Options - who should use ?
The easiest answer to this is if you are not sure - do not use these installers - they are aimed at corporate system administrators - not general users, so if you are not sure - use the default installer provided and not the MSI installer option !!!

FREE OCR Support
The new OCR functionality available at no charge in both the free and licensed PDF-XChange Viewer, requires the use of build 200 of the Viewer or later. By default the installations includes 4 default language support (English, French, German & Spanish). Additional Language Extension packages are available here:


If PDF-XChange Viewer build 200 or later has been installed without the OCR Base Languages support, the Base Language Pack will need to be downloaded and installed prior to any other of the available language packs.
