Protect, unlock, and sign PDF files safely

Sensitive PDFs deserve basic safeguards. Protect PDF adds a password when a tool engine supports it. Unlock PDF helps when you own the file and forgot access—never use unlock tools on documents you are not allowed to open.

Signing

Sign PDF and Request Signatures cover simple approval workflows. For high-stakes legal signatures, use a dedicated e-sign provider that meets your jurisdiction’s requirements.

Privacy habits

Do not paste passwords into public chats. Prefer short-lived download links. AnyFilePDF stores uploads temporarily and does not keep document contents in MySQL logs.
