How it works

1. Upload your file

Drag and drop or choose a PDF file from your device. Everything is checked against its real file type before processing starts.

2. We process it

Your file runs through an isolated job dedicated to PDF to PDF/A, with clear progress so you always know what stage it's at.

3. Download the result

Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.

What is PDF to PDF/A?

PDF to PDF/A converts a PDF into PDF/A, the ISO standard for long-term archiving. A PDF/A file is self-contained, so it can still be opened and displayed the same way years from now.

Common uses

Legal and government records. Submit documents to bodies that require archival PDF/A.
Long-term storage. Keep reports and contracts in a format designed to last.
Library and records management. Meet digital preservation requirements.
Consistent display. Avoid dependence on external resources that may disappear.

Tips for best results

Most PDFs from Word, LibreOffice or "Print to PDF" already embed fonts and convert cleanly.
Check which PDF/A level your recipient actually requires.
Interactive features and JavaScript are removed, as PDF/A requires.
Keep the original; PDF/A conversion produces a new file.

Your file stays private

PDF to PDF/A runs in an isolated processing job. Your upload and the generated result are deleted automatically after your download window ends — we don't keep copies, and download links are random, single-purpose, and expire.

Frequently asked questions

What is PDF/A?

PDF/A is an ISO-standardised version of PDF designed for long-term archiving, with everything needed to display it embedded in the file.

How do I convert a PDF to PDF/A?

Upload it to PDF to PDF/A, pick the version and download the converted file.

Which PDF/A versions are supported?

PDF/A-1b and PDF/A-3b. PDF/A-2 and the accessibility and unicode levels are not offered.

Will conversion always be fully compliant?

It is when the source PDF already embeds its fonts, which is true of most documents. A PDF using non-embedded system fonts is an edge case that may not be fully compliant.

Is it free?

Yes, free with no sign-up.

Do I need to sign up to use PDF to PDF/A?

No — this tool works without creating an account. There is no sign-up option at all right now.

What file types does PDF to PDF/A accept?

PDF to PDF/A accepts PDF files and produces a PDF result, up to 1 file per job.

Will my formatting or content be preserved?

We rebuild the document structure — text, layout, and images — as closely as the PDF format allows. Very complex source layouts (dense multi-column PDFs, unusual fonts) may need minor manual cleanup afterward.

What happens to my file afterward?

Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
