What you can do with Decrypt PDF
Decrypting removes a password you already know from a PDF, so the file opens freely afterwards — useful once a document no longer needs to be locked.
Stop retyping a password
Remove protection from a statement you open often so you are not entering the password every time.
Prepare a file for tools
Unlock a PDF so it can be merged, edited, or printed by software that will not touch protected files.
Clean up archives
Strip passwords from old documents you no longer need to keep locked.
Share an internal copy
Remove the password before storing a file in a trusted internal system.
Decrypt PDF on Windows without extra software
Windows doesn't include a built-in tool to decrypt PDFs, so people usually reach for Adobe Acrobat or one of many downloadable utilities — which means installers, licenses, update nags, and sometimes bundled extras you didn't want. On a managed work or school PC you often can't install anything at all.
ContinuePDF sidesteps all of that. It runs in the browser that ships with Windows (Edge) as well as Chrome and Firefox, with nothing to install and no admin password required. Drag your protected PDF in from File Explorer, decrypt it, and download unlocked PDF — and because it is all local, your documents never leave the PC.

Pro tip
You need the current password to remove it — this unlocks files you are authorised to open, it does not crack unknown passwords. Once unlocked, treat the file as sensitive again if it holds private data, since anyone can now open it.
Frequently asked questions
Can this open a PDF if I do not know the password?
No. Decrypting requires the correct password; it removes protection you already have access to rather than bypassing security on a file you cannot open.
Is the file completely unprotected afterwards?
Yes. Once the password is removed, the downloaded PDF opens without any prompt, so store or re-encrypt it accordingly if it is confidential.
How do I decrypt a PDF on Windows?
Open Decrypt PDF in Edge, Chrome, or Firefox on your Windows PC, drag your protected PDF in from File Explorer, run the tool, and unlocked PDF saves to your Downloads folder. No installation needed.
Can I use this on a work computer that blocks installs?
Yes. Because Decrypt PDF runs entirely in the browser with no installation, it works on managed Windows PCs where you don't have permission to install software.
Is ContinuePDF free to use?
Yes. ContinuePDF and all of its tools, including Decrypt PDF, are free with no signup required. Because documents are processed in your browser rather than on our servers, we can offer the full feature set at no cost.
