What this tool does
The checker measures every page, identifies common A-series and US paper sizes, groups repeated dimensions, and creates a downloadable CSV report.
Privacy note: selected files are handled by JavaScript running on your device. The application does not intentionally transfer document contents to a BQ server. Browser extensions, managed-device policies, and the browser itself remain outside the site’s control.
Compatibility note: PDF is a complex format. Very large, encrypted, malformed, digitally signed, or unusually constructed files may not process correctly. Keep the original document until you have checked the result.
Frequently asked questions
Does the checker modify the PDF?
No. It reads page boxes and produces a separate CSV report.
Why can a size be listed as custom?
The page dimensions do not closely match a supported standard size.
Does rotation affect the reported orientation?
The report includes the page rotation and calculates displayed orientation accordingly.
