Photo & Signature Resizer for Online Forms
Resize your photo, signature or thumb impression to the exact size (cm or pixels) and KB limit asked for in government and exam forms.
cm are converted at 200 DPI. The preset limits are common ones; always use the size written on your form.

Why forms reject your photo or signature
Online application portals check three things: the file type (usually JPG), the file size in KB (often a minimum and a maximum), and sometimes the dimensions in cm or pixels. A phone photo is several MB, so it is rejected. This tool sets all three in one step.
How to use it
- Pick a preset, or type the exact width, height and KB limits from your form.
- Use Crop to fill for photos and Fit with white border for signatures so nothing gets cut.
- Sign with a black pen on plain white paper and photograph it in daylight for a clean signature.
- If the file comes out below the minimum KB, increase the width and height a little.

Frequently asked questions
How do I resize a signature to 10 KB to 20 KB?
Choose the Signature preset (or type your form's size), set Min KB to 10 and Max KB to 20, choose your signature image and press Resize. Download the JPG and upload it to the form.
Why is my photo rejected by the online form?
Most forms check the file type, the file size in KB and sometimes the dimensions. A phone photo is usually several MB, so it must be resized to the limit given on the form.
Are my photo and signature uploaded?
No. Resizing happens inside your browser and the files never leave your device.
