- “2 pages were converted to images because their fonts weren’t included.”

Questions
Is my file uploaded?
No. Convert to PDF/A runs on your phone, in airplane mode too. Dokulo has no server for files.
Why PDF/A-2b?
It is the level many authorities and courts accept for filing and long-term storage.
What if a font is missing?
That page is converted to an image so the file still validates, and the result names how many pages.
Do I need Pro?
You can run it once on a real file and keep the result. After that, Pro unlocks it for good: €9.99, one-time, no subscription.
