How to use
- Choose your photo. A clear phone camera picture is fine.
- Drag and zoom so your face (or signature) fills the frame.
- For signatures, keep “Clean background” on so the paper turns pure white. Tap Make. The tool sets the exact pixel size and keeps the file within the KB limit.
- Download the JPG and upload it to the application form.
Frequently asked questions
Is my photo uploaded to your server?
No. Cropping, resizing and compression all happen inside your browser. Your photo and signature never leave your phone or computer.
The form says my file is too small. What do I do?
Some forms have a minimum size (for example 20 KB). This tool automatically raises the file to the minimum without changing how the image looks, so it will be accepted.
Do I need to pay or sign up?
No. The tool is free and needs no account.
My iPhone photo won’t open
Chrome and some Android browsers can’t read HEIC photos. Take a screenshot of the photo and upload the screenshot, or set iPhone Camera → Formats → Most Compatible.
