PDF to PDF/A conversion is not available
PDF/A is an archival standard that requires embedded fonts, device-independent colour with output intents, specific metadata and no encryption or external dependencies. Producing – and verifying – compliant files needs a validating conversion engine that is not available as a browser-side library here, so this tool is intentionally disabled rather than producing files that merely claim to be PDF/A.

What you can do here instead

Frequently asked questions
Why not just set a PDF/A flag?
Adding identification metadata without meeting the requirements produces a file that fails validation and falsely claims compliance.
Will it be added?
Only if a standards-validated conversion path can run entirely in the browser.
