What PDF to PDF/A does
Adds the metadata and color profile PDF/A archival format requires, for long-term storage and compliance. PDF/A is an ISO-standardized version of PDF built for long-term archival storage, often required by legal, government, and institutional record-keeping systems. This tool adds the core requirements — XMP metadata and an embedded sRGB color profile — that most PDF/A workflows expect, though it isn't run through a formal PDF/A validator, so it's a best-effort conversion rather than a certified compliance guarantee.

Frequently asked questions
Is the output guaranteed to be fully PDF/A compliant?
This adds the core requirements — XMP metadata and an embedded color profile — but isn't run through a formal validator, so complex source PDFs may not pass every compliance check.
Why does my organization need PDF/A?
PDF/A is an ISO standard for long-term archiving — it's often required for legal, government, or institutional record-keeping.
What's the difference between PDF and PDF/A?
PDF/A adds stricter requirements — embedded fonts, a defined color profile, and specific metadata — intended to guarantee a document displays identically decades from now, which standard PDF doesn't guarantee.
Should I validate the output with a dedicated PDF/A checker?
For strict compliance requirements (like legal or government filing), running the output through a formal PDF/A validator is a good extra step, since this tool's conversion is best-effort.
Is there a dedicated PDF to PDFA converter online?
Yes — this tool adds the core metadata and color profile requirements most PDF/A workflows expect, though for strict legal compliance a dedicated validator is worth running afterward.
Is this a real PDF/A converter online for archival format?
Yes — this PDF/A converter online is free and works to convert PDF to archival format; while it isn't a certified PDF/A compliance tool, it covers the core requirements most PDF long term archiving workflows expect.
Is PDF to PDF/A free?
Yes, and there is no sign-up, watermark or daily limit — everything runs in your browser rather than on a metered server.
