Questions

What does it check?

Object structure, the cross-reference table, page tree integrity, font embedding, encryption, and PDF/A conformance where relevant.

My file opens fine but fails validation. Should I care?

Often not for reading, but yes if it is going into an archive or a system that validates on ingest.

Security note

Files are checked to be what they claim (by content, not extension), processed in a sandboxed worker with no network, and deleted on the schedule your plan sets. We do not run antivirus and do not claim to — please do not upload files you do not trust. Read the security page.
