Auditing a Legal or Financial PDF

Check what actually changed, remove anything sensitive, then lock it down.

Comparing versions has to come first, since it's the only way to actually know what changed rather than assuming -- this matters most for exactly the kind of document (legal, financial) where an unnoticed change has real consequences. Redaction follows once it's clear what's actually in the document, since you can't properly remove sensitive content you haven't identified yet. Locking the file is the true last step, applied only to the final, already-audited and redacted version.

Each step opens as its own tool -- download from one, upload into the next, same as any free tool on the site.
