Frequently asked questions
Is PDF Bookmark Editor free to use?
Yes. PDF Bookmark Editor is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does PDF Bookmark Editor upload your PDF to a server?
No. PDF Bookmark Editor 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 PDF Bookmark Editor.
Do I need to install anything to use PDF Bookmark Editor?
No installation is needed. PDF Bookmark Editor runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use PDF Bookmark Editor on a phone or tablet?
Yes. The PDF Bookmark Editor 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. PDF Bookmark Editor keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
