PDF Page Dimensions — frequently asked questions

Why are the dimensions not exactly A4?+

Many PDFs are a hair off the ISO size. Anything within about 1mm is labelled with the matching named size; the rest show as 'Custom'.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The AI tools that used to send extracted text to a server are currently disabled.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
