Frequently asked questions
Is Unlock PDF free to use?
Yes. Unlock PDF is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Unlock PDF upload your PDF to a server?
No. Unlock PDF processes your PDF inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Unlock PDF.
Do I need to install anything to use Unlock PDF?
No installation is needed. Unlock PDF runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Unlock PDF on a phone or tablet?
Yes. The Unlock PDF interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your PDF when I close the tab?
It is discarded. Unlock PDF keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
