Accepts: .PDF
Note: True PDF/A compliance requires embedded fonts, ICC color profile, and XMP metadata — beyond what browsers can do reliably. This tool creates a browser-made PDF/A-style approximation and writes simple PDF/A-style producer/subject markers. It is not certified PDF/A and may fail preflight checks. For certified archival, use Adobe Acrobat or veraPDF.

What a PDFA file is, in plain terms

If you searched “PDF to PDFA”, you almost certainly want a PDF you can file away and reopen years later that still looks right. PDFA — the typed-out form of PDF/A — is the everyday name for that archive-friendly PDF. This converter takes the PDF you upload and writes PDF/A-style markers into it so it reads as an archival copy.

Honest note: a fully certified PDF/A file needs embedded fonts, an ICC colour profile and XMP metadata, which a browser cannot reliably add. This tool produces a browser-side PDFA-style approximation and is not certified ISO PDF/A; it may not pass a strict preflight. If you need guaranteed compliance, run the result through veraPDF or Adobe Acrobat Pro.

Everything happens on your device. Your selected files are processed in your browser and are not uploaded to our server; rendering uses PDF.js and the output is written with pdf-lib. Close the tab and the working session clears; your downloaded file stays with you.

PDFA questions, answered

What is a PDFA file?

A PDFA (written PDF/A) file is a version of a PDF meant for long-term storage — self-contained so it should look the same years from now. This tool writes PDF/A-style markers into your PDF so it reads as an archive-style copy.

Is PDFA the same as PDF/A?

Yes — PDFA is just the typed-out spelling of PDF/A. People search both ways; they mean the same family of archival PDF formats defined by ISO 19005.

How do I convert a PDF to PDFA for free?

Drop your PDF above, pick the PDF/A-style label, click Process, and download the result. It runs entirely in your browser — no upload, no account, no watermark.

Will the PDFA file open like a normal PDF?

Yes. The output is still a standard .pdf and opens in any reader. The PDF/A-style markers sit on top; they do not block normal viewing or printing.

Is this a certified PDF/A converter?

No. It is a browser-side approximation that adds PDF/A-style markers; it does not embed fonts, ICC profiles and XMP the way a certified converter does. For certified, validated PDF/A, use Adobe Acrobat Pro or veraPDF and check the result.
