Frequently asked questions

What is PDF/A?

PDF/A is an ISO-standardized form of PDF designed for long-term preservation.

Is PDF/A a different file type?

It is still a .pdf file. PDF/A adds archival requirements to the PDF format.

Which PDF/A version should I use?

OneDo Hub recommends PDF/A-2b for most ordinary archival documents. Your institution may require a specific PDF/A version.

Why can't some PDFs be converted?

Some documents depend on missing fonts or contain features that cannot be transformed safely without changing the document. OneDo Hub won't label a file PDF/A unless the selected archival requirements are met.

Will conversion change how my document looks?

The goal is to preserve the visible document. OneDo Hub verifies representative rendering before offering a compliant result.

Can a password-protected PDF be PDF/A?

PDF/A does not permit normal PDF encryption. Unlock the document before converting it.

Does PDF/A make a scanned document searchable?

No. Use OCR PDF if you also need searchable text.
