About PDF to PDF/A

PDF to PDF/A converts a document to the ISO standard for long-term archiving that courts, governments and archives often require. Fonts are embedded and colours defined, so the file will look the same decades from now.

Choose PDF/A-2b (suits most needs), PDF/A-1b for older systems, or PDF/A-3b if attachments are allowed.
