About this tool
What is Image Upload Requirement Checker?
Image Upload Requirement Checker compares your picture against the rules a portal gives you: maximum size in KB, minimum and maximum width and height, allowed formats and whether the image must be square. You see a pass or fail for each rule, so you know exactly what to change.
Useful when you need to
- Confirm a photo meets an exam form's requirements
- Check a signature scan against pixel and size limits
- Avoid last-minute upload errors before a deadline
- Test an image against custom portal rules
