Frequently asked questions

Is it really free?+

Yes. PDF to PDF/A is 100% free — no sign-up, no watermarks. We cap usage at 10 operations per day per visitor to keep the service fast for everyone.

Are my files private?+

For most tools your file never leaves your browser — everything runs locally. For Office conversions (which need LibreOffice on our server), files are processed and deleted immediately after conversion.

Is there a file size limit?+

Browser-based tools depend on your device's memory; most files under 200 MB work fine. Server-side conversions are capped at 50 MB.
