What if I have only the owner password?

If only owner password is set (no open password), the PDF can be opened freely — Unlock removes restrictions like print/copy locks.

No. We strip encryption only — content is byte-perfect identical.

Yes if you are the owner or have permission. Do not unlock files you don't have rights to.

Do you log my password?

No. The password is used in-memory to decrypt and immediately discarded.

Why won't my password work?

Check caps lock, character encoding, and any regional keyboard differences. PDF passwords are case-sensitive.

Unlock PDF

pdfty's unlock tool removes the open and owner passwords from a PDF you legitimately have access to. Just upload, type the password you know, and download an unprotected copy.

We do NOT crack or guess passwords. If you don't know the password, no online tool that respects encryption can help — the AES-256 used by PDFs is mathematically secure.

Useful when you receive a protected PDF and want to share with colleagues without re-entering the password every time, or when you want to merge/split/edit a protected file.

Both files deleted from our servers within 1 hour.

Frequently asked questions

No. Modern PDF encryption (AES-256) is unbreakable without the password. We refuse to claim otherwise.
