About PDF to PDF/A

PDF to PDF/A converts a PDF into the ISO archival format (PDF/A-1b, 2b or 3b) that public bodies, courts and registries ask for: fonts embedded, colors defined, nothing that depends on outside resources. Conversion runs on our servers with Ghostscript.

How to use PDF to PDF/A

  1. Add the PDF and choose the PDF/A level, usually 2b.

  2. The file is uploaded over an encrypted connection and converted; the result is checked for the PDF/A mark.

  3. Download the archival PDF; the upload is deleted at once.

Frequently asked questions

Which level should I choose?
PDF/A-2b suits almost everything and allows transparency and modern compression. Choose 1b only when a system demands it, and 3b when the PDF must carry attachments.
Will the document look different?
Rarely. Colors are converted to a defined color space and fonts embedded; what the level forbids, such as transparency in PDF/A-1, is flattened.
Can a protected PDF be converted?
No; PDF/A forbids encryption. Remove the password with Unlock PDF first.
Do courts, registries and archives accept PDF/A-2b?
Most ask for PDF/A-1b or 2b, and 2b is accepted wherever 1b is not demanded by name. Check the requirement and pick the level it names.
How do I check that the result is really PDF/A?
The file carries the PDF/A identification in its metadata, and readers such as Acrobat show a PDF/A banner. Free validators such as veraPDF confirm it too.
