Don’t risk losing users’ trust: future-proof your PDF implementations

July 2024 by Peter Wyatt (PDF Association)

To avoid confusing and frustrating users, applications can and should be robustly prepared for significant changes to PDF – with end user messaging in mind – well before files start to occur in the marketplace.

As PDF’s technical community continues its work on defining a future version of PDF it must consider the impact of these changes on today’s software, and how implementers can best support end users.

Web browsers offer a lot of relevant experience in terms of how they manage similar incompatibility issues, including missing functionality. For example, “reporting to a user” does not always have to be via a primary user interface dialog or prominent banner but might be via logs, a status bar symbol, or an on-screen widget.

The key point is that an end-user must have some means of learning that an incompatibility has been detected between their software and the document they’ve opened and are (presumably) trying to understand!

PDF has always been and always will be fully extensible; PDF software should always be written to reflect that fact.
