Frequently asked questions
Is Clean PDF free to use?
Yes. Clean 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 Clean PDF upload your PDF to a server?
No. Clean 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 Clean PDF.
Do I need to install anything to use Clean PDF?
No installation is needed. Clean PDF runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Clean PDF on a phone or tablet?
Yes. The Clean 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. Clean PDF keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
