What does this PDF-to-PDF/A tool do?

It converts a PDF into PDF/A for long-term archiving: fonts are embedded and reliance on external pieces that may vanish later is reduced. Some universities and records offices require it.

Upload, download the PDF/A, then open it in a reader that can validate if the recipient wants a conformance report. Rich media files may be simplified during conversion.

PDF/A is for archiving; use compression if size is the issue. Files are deleted after conversion. Check which PDF/A profile the office asks for.

When do you need PDF/A?

Submitting a thesis to a university library.
Filing administrative decisions in a records system.
Preparing a tender pack that mandates PDF/A.
