How to: Validate PDF/A
- Select one or more PDFs.
- Choose the PDF/A level or use the one the file claims.
- Read the pass/fail checklist or download the report.
Courts, government portals and archives often demand PDF/A, and rejected uploads usually come down to a handful of problems: missing fonts, no PDF/A identification in the metadata, no colour profile, encryption or JavaScript. Fileopia checks these in your browser and explains each issue in plain English so you know exactly what to fix.
Common uses
- Check a court e-filing or tax document before submitting.
- Verify scanned archives meet PDF/A-2b requirements.
- Audit a batch of exported reports for long-term storage.
- Confirm a converter really produced PDF/A.
Tips for best results
- 'Claimed level' reads the level the file declares in its metadata.
- Most portals accept PDF/A-2b; check their exact requirement.
- Font problems are fixed by re-exporting with 'embed all fonts'.

- Check the network: open your browser’s developer tools (F12 → Network) while processing; you will see no file upload requests.
- Nothing to delete: close the tab and the data is gone – there is no server copy, no retention period and no account.
