What is Unlock PDF and how does it work?

Unlock PDF removes the password from a PDF you can already open, so you don't have to type it every time. It only works on documents you have the password for — it is not a password cracker.

How do I use Unlock PDF online?

Upload your file using the box above — drag it in, browse for it, or bring it in from your cloud storage. A preview appears so you can check you've picked the right file. Run Unlock PDF, then download the result. You can rename it before you save it.

Is my file secure when I use Unlock PDF?

Yes. The file you send to Unlock PDF travels over an encrypted HTTPS connection and is processed automatically on our servers. It is never made public, never shared with anyone, and nobody reads it.

Does HuntPDF store my files after Unlock PDF has run?

No. Your upload is deleted the moment Unlock PDF finishes with it, and the file it produces is removed as soon as you have downloaded it, or when you upload another file, or when you close the page. Nothing is kept, and nothing is used to train anything.

Will the original quality and formatting be maintained?

Yes. Every page, image and font stays exactly as it was. The only change is that the password prompt is gone.

Can I use Unlock PDF on mobile?

Yes. Unlock PDF works in any modern browser on phones and tablets — iPhone, iPad or Android — with nothing to install. You can upload straight from your device or from your cloud storage.

Can I rename my file before downloading it from Unlock PDF?

Yes. The file Unlock PDF gives you back keeps the name of the file you uploaded by default. If you'd rather call it something else, edit the name in the field next to the download button before you save it.

Do I need to install any software to use Unlock PDF?

No. There is nothing to download, install or sign up for — Unlock PDF is used from your browser and does the work on our servers, so it behaves the same on Windows, macOS, Linux, Android and iOS.

How long does Unlock PDF take?

Most files are finished in a few seconds. A large or page-heavy file takes a little longer, because Unlock PDF runs on our servers rather than on your device — but you won't be waiting around. You can upload files up to 250MB.

Is Unlock PDF free to use?

Yes. Unlock PDF is free, with no signup, no watermark on the result and no daily limit for normal use.
