About Any online form
Most college admission, scholarship, Aadhaar-related, ration card and job forms only give a KB limit. Pick the limit your form shows, and change the pixel size under Size settings if needed.
Tips so your signature isn’t rejected
- Sign with a black or dark-blue pen on plain white paper.
- Photograph it in good light, then turn on “Clean signature background” to remove grey shadows.
- Crop close to the signature, leaving only a small white border.
- Don’t sign in CAPITAL letters. Many forms reject that.
- Use the same signature you will sign at the exam centre.
Frequently asked questions
Is my photo uploaded to a server?
No. All resizing, cropping and compression happens inside your browser on your own device. Your photo never leaves your phone or computer.
How do I reduce a photo to under 50 KB (or 20 KB)?
Choose a preset or enter your maximum in Size settings → Max size (KB). The tool finds the best JPG quality that stays under that limit.
My form needs at least 10 KB, but my image is smaller. What do I do?
Enter the minimum in Min size (KB). The tool raises the quality and, if needed, adds harmless padding inside the JPG so it meets the minimum without changing how it looks.
What is DPI and does it matter?
DPI tells programs how big the image should be when printed. When a form gives a size in cm or inches, the pixel size is calculated from the DPI, and the DPI is saved inside the file.
Can I use it on my phone?
Yes. It works in any modern mobile browser. Drag with one finger to move and pinch to zoom.
