How to photo size checker
- Optionally pick your exam or ID upload from the list.
- Drop in your photo or signature.
- Read the format, pixels, KB, DPI and print size — with a pass or fail for each requirement.
- If something fails, follow the link to the resizer that makes it fit.
What you can use it for
- Checking an exam photo or signature before the final submit
- Finding out why a portal says “invalid dimensions” or “file too large”
- Reading the DPI and print size of a scan
- Confirming a resized file really is JPG, not a renamed PNG
