Check a file against an upload requirement
Find out in one click whether your file already meets a published requirement — size, format, and dimensions — before you upload it.
How it works
- Your file is inspected in your browser; nothing is uploaded.
- Each rule of the selected requirement is checked and reported PASS or FAIL with the exact numbers.
- Every preset cites its official source and the date we last verified it.
