Unlock PDF — Remove a Password, in Your Browser
Remove the password from a protected PDF you own — the file is decrypted in your tab and downloaded by you, with nothing transmitted.
Unlock PDF
Remove a password from a PDF you own
Use this on documents you own or are authorized to access. The decryption happens in your tab; the unlocked file is downloaded by you and nothing is transmitted.
How to unlock a PDF in your browser
- Choose the protected PDF — one you own or are authorized to access.
- Type its open password. The tool checks it against the file's encryption locally, with no network round-trip.
- Hit Remove Password & Download. You get back the same document, identical page by page, minus the encryption.
Why remove a password at all?
Legitimate reasons exist and are common: a colleague password-protected a file and then emailed you the password (unlocking saves you from re-typing it in every reader); you are archiving documents and your archive system cannot store password-protected items; you are merging or editing a file that your own toolchain chokes on. The unlock is reversible by design — you could re-protect the result immediately — which is exactly why the tool is safe to have on the page.
What if I don't have the password?
Then this tool cannot help, and that is intentional. A PDF's encryption exists to make the file useless without the key, and no honest tool — browser or server — changes that. If the file is yours and the password is lost, the remedy is the original document, re-protected with a password you keep.
Does it change the document?
No. Unlocking removes the encryption layer and nothing else: pages, text, fonts, links, form fields and metadata are preserved exactly. The output opens identically to how the input rendered once you were inside it.
Where does the password go?
Nowhere. It is read from the field, checked against the file's encryption by the local WASM engine, and then it exists only in the tab's memory until the page is closed. There is no server to send it to — the whole point of the architecture is that the file and the password meet on your machine and nowhere else.
FAQ
- Is my file uploaded to a server? No. The tool runs entirely in your browser — your file never leaves your device. You can verify it yourself: open the network panel and there is no upload request while you work.
- Do I need an account, and is it free? No account and no cost. It is free to use — no signup, no paywall, no daily limit.
- Which browsers does it work in? Any modern browser — Chrome, Edge, Firefox and Safari — on desktop or mobile.
- Is there a size limit? There is no server-side limit because nothing is uploaded. Practical limits come from your device's memory, which comfortably covers normal documents and photos.
- Does it work with encrypted PDFs? Standard PDFs work in every tool. If a file is password-protected, Unlock PDF opens it for you when you have the password, and Protect PDF applies a new 256-bit AES password. No tool bypasses encryption without the key.
