Common questions

Is PDF to PDF/A free?

Yes — PDF to PDF/A is free with no sign-up, no watermark and no daily limit on this tool. Heavier operations (OCR, conversion) have a generous daily quota on the free plan and are unlimited on Pro.

How do I convert pdf to pdf/a?

Open PDF to PDF/A, drop your file, set the options, and download the result in a few seconds — processed securely, no queue and no ads.

Are my files safe?

Files are sent over an encrypted connection and deleted automatically after processing. No one else can access them and they are never used for anything but your task.

What is PDF/A and why would I need it?

PDF/A is the ISO 19005 archival profile: fonts are embedded and anything that could render differently in future is removed, so the file looks the same decades from now. Courts, government bodies and record-keeping systems often require it.

What changes in my document?

Visually, nothing. Under the surface fonts are embedded and features that are not allowed in an archival file are converted, which can make the file slightly larger.
