PDF
Upload one or more PDFs and each gets PDF/A identification metadata (XMP) added, aimed at long-term archiving. This is a best-effort pass, not a certified ISO 19005 conformance conversion.
How to use PDF to PDF/A
- Add one or more PDF files.
- Tap Run.
- Download the tagged PDF(s).
FAQ
Is the output guaranteed PDF/A-conformant?
No — true PDF/A conformance also requires things like embedded ICC color profiles and font-embedding checks across the whole file, which this browser-based pass doesn't fully verify. It adds the standard PDF/A identification metadata, which is honest and useful, but not a certified conversion.
What's it good for, then?
It's a lightweight way to flag a PDF's archival intent for systems that check for PDF/A metadata, without needing to install desktop software.
