How do I know my form's requirements?

They are listed near the upload button on the form — look for a maximum file size in KB or MB, required pixel dimensions, and accepted formats such as JPG or PNG. Enter whatever the form specifies and leave the rest blank.

What does the checker actually fix?

It resizes the image to fit your dimension rules, converts it to an accepted format, and compresses it under the KB limit — all at once, so the downloaded file meets every rule you entered.

Does my photo get uploaded?

No. The check and the fix both run in your browser using the Canvas API. Your file never leaves your device.

It still got rejected — why?

Size, dimensions, and format are only the mechanical rules. Portals may also require a specific background color, head position, or expression, which this tool does not judge. Re-read the form's photo guidelines for those.
