Photo and Signature Resizer for Forms
Resize a photo or signature to the pixel size and KB limit your admission, exam or job form asks for. It all happens in your browser. Nothing is uploaded.
Check your form's instructions for the exact pixel size, KB range and format. Output is JPEG. Presets are common sizes only, not tied to any one exam. The 3.5 x 4.5 cm preset is computed as cm to inches times 300 dpi.
Common questions
Is my photo uploaded?
No. The image is resized in your browser and never leaves your device.
What if my form wants a different format or a minimum size?
This tool outputs JPEG under your maximum KB. If your form also asks for a minimum size or another format, read its instructions and adjust the size boxes.
Is this calculator free?
Yes. It is free to use and needs no sign-up.
Is the result official?
No. Results are estimates for your own planning. Check your college or university rules for the official method.
