In short Password Protect PDF is a free online tool on inputtesthub.com that encrypts a PDF with a password and sets permissions for printing, copying and editing. 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 Password Protect 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 Password Protect PDF

The Password Protect PDF encrypts a PDF with a password and sets permissions for printing, copying and editing. 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

  • Sending a confidential document by email.
  • Restricting copying on a distributed report.
  • Adding a password before uploading to shared storage.
The encryption happens in your browser, so the password is never transmitted — but it also means we cannot recover it. Write it down before you close the tab. PDF permissions (no printing, no copying) are advisory: compliant readers honour them, but they are not real security.

Frequently asked questions

Does the Password Protect PDF cost anything?
There is no cost and no cap. The Password Protect PDF is not a demo of a paid product, so nothing is held back or watermarked.
Is my data uploaded anywhere?
No. The Password Protect PDF runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Who is the Password Protect PDF for?
Typical uses: sending a confidential document by email. Restricting copying on a distributed report. Adding a password before uploading to shared storage. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there a catch?
The encryption happens in your browser, so the password is never transmitted — but it also means we cannot recover it. Write it down before you close the tab. PDF permissions (no printing, no copying) are advisory: compliant readers honour them, but they are not real security.
How large a file can I use?
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.
