Paste in the photo or signature a form keeps refusing and find out exactly which rule it breaks - size, dimensions, format or DPI - then fix it in one click.
Your file never leaves your device
This tool runs entirely inside your own browser. Your file is not uploaded, not stored, and never reaches our servers. It is not a policy we promise to follow; there is simply no upload step in this tool at all. The one thing sent is a short note that you used the tool, for your own history.
"Photo and signature invalid" — but why?
Application portals almost never say which rule your file broke. They just refuse it, and you're left guessing between size, dimensions, format and DPI. Drop the file in below, pick the exam you're applying to, and this tells you exactly which requirement fails — then fixes it for you in one click.

Common questions
The portal still rejects it after I fixed everything here.
Then it's almost certainly one of the things no tool can see from the file itself: the photo being older than the exam allows, a missing name-and-date strip across the photo, a coloured or patterned background where a plain one is required, or the signature being in the wrong ink colour. Re-read the instruction page for those four — they're the usual culprits once the numbers are right.
My file's DPI shows as "not recorded". Is that a problem?
Usually not. Plenty of portals mention a DPI but only ever check pixels and file size, and most phone cameras and editors don't write a DPI value at all. If yours genuinely enforces it, the resizer can stamp the right value into the file for you.
Do you keep the file I'm checking?
No. It's read by your own browser and never sent anywhere. This tool is free and doesn't even record that you used it.
