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