Frequently asked questions
Is Page Size Checker free to use?
Yes. Page Size Checker is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Page Size Checker upload your file to a server?
No. Page Size Checker processes your file 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 Page Size Checker.
Do I need to install anything to use Page Size Checker?
No installation is needed. Page Size Checker runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Page Size Checker on a phone or tablet?
Yes. The Page Size Checker interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your file when I close the tab?
It is discarded. Page Size Checker keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
