Debenu Quick PDF Library 9 Released

Today we’re excited to announce the release of Debenu Quick PDF Library 9.

This new major version of our PDF SDK for Windows Desktop and Server development is an important step forward for the library and we can’t wait for you to get your hands on it.

The new Debenu Quick PDF Library 9 is even more stable, faster and useful, with some great new features and enhancements.

What’s new

  • PDF stamp annotations (Approved, Declined, etc)
  • Support for files larger than 2GB
  • PDF repair functionality
  • Performance improvements*
  • Vertical text mode supported by the renderer
  • 70+ enhancements, bug fixes and features
  • Full list of changes

* Performance increases are most notably seen in ExtractFilePages, ExtractPageText, DAFindPage and the direct access functions that use DAFindPage internally. Other general speed improvements have been made to the library.

Try the new version

A full list of the changes in Debenu Quick PDF Library 9 can be found on our product updates page. You can also download a 30 day limitation-free trial version of the library.


Debenu Quick PDF Library 9 is a major new version of the product which means that the upgrade process is different from the minor version upgrade process, namely, upgrades aren’t free unless you meet certain requirements.

Free upgrades

Customers who purchased version 8 of Debenu Quick PDF Library on or after the 17th of July, 2012 (within 60 days of version 9’s release) or who own an active Premium Upgrade Protection subscription are eligible for free upgrades from version 8 to version 9.

Contact our sales team if you fall into this category and we’ll help you out.

Purchase an upgrade

An upgrade from version 8 to version 9 can be purchased at a discount (starting price is $209.40) through our online store. Users can upgrade their Single Developer, Multiple Developer or Source Code licenses to version 9. It’s also possible to purchase Premium Upgrade Protection with your upgrade purchase.

For example, if you own a Single Developer License + Standard Upgrade Protection for version 8 of Debenu Quick PDF Library then you will need to purchase the Single Developer Upgrade License + Standard Upgrade Protection (8.x to 9.x) product in order to upgrade to version 9 — though you can choose to buy the Premium Upgrade Protection version of that product if you prefer.

Branding changes

In years gone by Debenu has sold applications under a few different brands, the two main ones being “Quick PDF” and “ARTS PDF”. In 2012 we’re undertaking a re-branding effort to consolidate all of our brand names as “Debenu”. This means that Quick PDF Library is now Debenu Quick PDF Library. We’re keeping the “Quick” in there for a while so that customers don’t get too confused, but this will eventually be removed from the name.

This means that you’re going to see more and more references to Debenu PDF Library and less and less references to Quick PDF Library or Quick PDF.

The branding change will be most evident in the changes to the binaries that we provide for Debenu Quick PDF Library and in the class names. For example, the ActiveX edition would have previously had the file name “QuickPDFAX0911.dll” but it will now be called “DebenuPDFLibraryAX0911.dll”.

We will post more information about the branding changes to the API and binary file names on the website.


As always we’d love to hear your thoughts on the new version of Debenu Quick PDF Library. If you have any questions, comments or general feedback, please let us know.
