Please note that as of 12th March 2021, this SDK product is no longer available to purchase, and maintenance agreements/product updates for it are expected to cease at the end of 2022. When all maintenance agreements have expired we will no longer be releasing any new SDK updates, although all existing products will continue to operate as normal. We thank you for your interest and use of these products, but they have come to represent a very small fraction of our sales revenue, and it has become clear that our business model should be updated to exclude them. Further information about this is available here.

The PDF-XChange Drivers API SDK provides developers with a comprehensive set of virtual drivers to generate Adobe®-compatible PDF files from their software applications using our best-selling PDF-XChange print drivers for Windows XP & later (32/64 bit). These drivers offer the best compression/optimization available for PDF files generated from a virtual PDF driver - small files that are generated quickly and efficiently.Developers can use the PDF-XChange Drivers API to tweak and control almost all of the functionality available in the end-user version of the PDF-XChange virtual print driver - PDF-XChange Standard. Further information on the functionality available is detailed in the PDF-XChange Drivers API SDK evaluation version, which you can download and experiment with for free.

Tracker Software also provides complete 'slimmed down' client installers (in both 32 & 64 bit drivers) that you can provide to your clients. Alternatively, you can wrap it within your own installation process - but you must use this installer as it contains a mechanism that ensures unlicensed use is not possible in 'open' mode without the generation of evaluation PDFs. It also ensures safe and correct installation for Windows XP and later, and is TS and Citrix Metaframe supported. Note that silent installation is also supported for the options detailed above.

Version 5: Microsoft/Citrix Terminal Server compatible*.
Version 4: Microsoft/Citrix Terminal Server compatible*.

* 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.

Demo Limits

Evaluation versions of our SDK software are fully functional, allowing the testing and full utilization of all SDK features. Developers need to be aware that any test documents will have a demo watermark placed on every page of any PDF created or modified with the evaluation versions:

We recommend that you use the evaluation SDKs extensively - prior to purchase - in order to to ensure that you are satisfied with the product, and only purchase when you are ready to recompile your completed application (with your license strings, which will remove the demo watermark restrictions) for distribution to your clients - as Tracker Software does not offer refunds subsequent to issuing licensing information.

    I have experience with using other sdk manufacturers (nova and amyuni). PDF-XChange Drivers is the Best !!

    I have tested about 10 other printer drivers and this one is clearly the best. It has all the features I needed and the API is very convenient and well documented. What's more, for the past 2 years I have been using this product, the company has provided excellent and fast support.
