In short Unlock PDF is a free online tool on inputtesthub.com that removes password protection from a PDF you can already open, so it can be edited and copied freely. It needs no account, no download and no payment, and there is no daily usage limit. Everything is processed inside your own browser, so the data you paste is never uploaded to a server.

How to use the Unlock PDF

  1. Add your PDF file or files by dropping them in.
  2. Arrange or configure them as needed.
  3. Download the finished PDF. Processing happens on your own device.

About the Unlock PDF

The Unlock PDF removes password protection from a PDF you can already open, so it can be edited and copied freely. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Removing a password from a file you own so colleagues can open it.
  • Clearing permission restrictions on your own document.
  • Making an archived PDF searchable again.
This only works on PDFs you can already open — either you know the password, or the file has permission restrictions but no open password. It does not break encryption or crack unknown passwords, and you should not use it on documents you do not have the right to modify.

Frequently asked questions

Are there any usage caps on the Unlock PDF?
No charge and no sign-up. There is no free tier to run out of because there is no paid tier — inputtesthub.com is funded by advertising rather than by metering the utility.
Does anything I enter leave my computer?
No. The Unlock PDF runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What problem does the Unlock PDF solve?
In practice it gets used for three things: removing a password from a file you own so colleagues can open it. Clearing permission restrictions on your own document. Making an archived PDF searchable again. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
This only works on PDFs you can already open — either you know the password, or the file has permission restrictions but no open password. It does not break encryption or crack unknown passwords, and you should not use it on documents you do not have the right to modify.
Is there a file size limit?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
