Unlock PDF

How to remove a password you already know

1. Drop the protected PDF onto the box above, or click it to browse.
2. Type the password you normally use to open the file. The eye button reveals what you have typed, which is worth using for anything long or copied from a password manager. If the file opens without a password and only blocks printing or copying, leave the box empty.
3. Press “Unlock PDF”. The first run fetches the decryption engine, so it takes a moment longer than later ones.
4. The decrypted copy downloads with -unlocked added to the filename. It opens with no prompt in Acrobat, Chrome, Edge, Preview and phone apps, and the pages, text and layout are unchanged.

What people use it for

Password prompts are useful in transit and a nuisance forever afterwards. Once a document has arrived somewhere safe, the password usually stops protecting anything and starts getting in the way.

• Bank and card statements that arrive encrypted every month and have to be opened one at a time.
• A payslip you need to forward to a mortgage adviser, who will not have your password.
• Utility or insurance documents you want to file in a folder that is already private.
• A protected report that has to be merged, split or printed in bulk, which most tools refuse to touch while it is encrypted.
• An old archive whose password you still have, but which now needs to be searchable alongside everything else.

Good to know

Be clear about what this is: it removes a password you already know, from a document that is yours to open. It cannot guess, crack, brute-force or bypass a password you do not have. There is no recovery mode, no dictionary attack and no hidden fallback — if a file asks for a password to open, nothing here can unlock it without that password, and that is deliberate. If the password is wrong you get a plain message saying so and no file at all, rather than a damaged or half-decrypted download, so a typo costs you nothing but a second attempt. A file that is damaged, or that has no password in the first place, gets its own message saying which it is.

The decryption runs on qpdf compiled to WebAssembly and executes inside this tab. That distinction is the reason to prefer it: an ordinary unlock website receives your confidential document and the password guarding it in the same upload, both landing on hardware you have never seen. Nothing of the sort happens here — the file is read from disk by your browser, decrypted in memory and handed straight back to you. The engine itself is downloaded from a public CDN the first time you use the tool, which is the only network request involved; your PDF is not part of it. Once the file is open, Merge PDF or Split PDF can work on it normally, and Protect PDF will put a password of your own choosing back on afterwards.

Questions people ask

I have forgotten the password. Can you help?

No. Neither this tool nor anyone at EditZap can retrieve or work around a password we never had. If the document came from a bank, an employer or an insurer, the sender can normally reissue it — that is the fastest route by a wide margin.

Does the unlocked file lose quality or formatting?

No. Decryption unwraps the document rather than rebuilding it, so pages, fonts, images, bookmarks and text selection stay exactly as they were. Only the encryption layer is gone.

What about a PDF that opens freely but blocks printing or copying?

Such a file has no password to open it; the restrictions are tied to a separate owner password instead. Leave the password box empty and press “Unlock PDF”: the file is decrypted the same way your PDF reader opens it, and the copy you download has no print, copy or edit restrictions. EditZap's other PDF tools open these files the same way, without a prompt. Only do this with documents you are entitled to print or copy.

Is my password sent anywhere?

It stays in the input field on this page and is passed to the decryption engine running in your browser. It is never transmitted, logged or saved, and closing the tab discards it.
