PDF to PDF/A

Convert a PDF into an archival PDF/A file.

PDF to PDF/A converts an ordinary PDF into the archival PDF/A format defined by ISO 19005. PDF/A embeds every font the document uses and keeps all of its content inside the file, so it no longer depends on outside resources and looks the same years from now on any compliant viewer. That makes it the standard choice for legal filings, government submissions, and records retention. We produce PDF/A-2b, a widely accepted level that preserves the visual appearance of your pages. Because the standard forbids anything that could change how a file renders over time, some interactive features are removed during conversion: embedded JavaScript, encryption, and audio or video are not allowed in PDF/A. Your file travels over an encrypted connection.

Frequently asked questions

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

PDF/A is an ISO-standardized version of PDF built for long-term archiving. It embeds all fonts and keeps everything the document needs inside the single file, so it stays readable and looks the same in the future without relying on outside resources. It is the format archives, courts, and government agencies ask for when a document has to be preserved unchanged for years.

Will my PDF look the same after conversion?

Yes. PDF/A-2b is designed to preserve the visual appearance of your pages, so the converted file looks like the original. What changes is under the hood: fonts get embedded and the file becomes self-contained so it renders the same way on any compliant viewer, now and later.

Is my original file changed?

No. You upload a copy and download a new PDF/A version. The file on your device is untouched. Note that PDF/A forbids some interactive features, so embedded JavaScript, encryption, and audio or video are removed during conversion; everything visible on your pages is preserved.
