Frequently asked questions

Is the output fully PDF/A compliant?

The tool adds the required metadata and conformance markers. For strict compliance verification, run the output through a dedicated validator like veraPDF after conversion.

What is the difference between PDF/A-1b, 2b, and 3b?

All three ensure long-term readability. PDF/A-2b adds JPEG 2000 and transparency support. PDF/A-3b additionally allows embedding of arbitrary file attachments. For most archival needs, PDF/A-1b is sufficient.

Will my existing content change?

Page content, text, and images are unchanged. Only metadata and conformance markers are added to the file structure.
