Resize Image to 10KB
Make a signature or small photo under 10 KB for strict form limits — processed in your browser, nothing is uploaded.
Resize & compress an image
The target is set to 10 KB. Drop a signature or photo and press Reduce image.
Quality is lowered only as much as needed; if that is not enough, the dimensions shrink too.
How it works
Upload your image
Click the upload box and pick any JPG, PNG or WebP image from your device.
Set new size
Type a new width or height — the ratio lock keeps your image perfectly in proportion.
Download
Optionally reduce quality, then download the smaller, resized image instantly.
About Resize Image to 10KB
Some online forms allow only 10 KB for the signature, thumb impression or a small photo. Resize Image to 10KB first looks for the best JPEG quality that fits, and only when that is not enough does it reduce the pixel size, so strokes and faces stay as clear as such a small file allows.
Signatures are the easiest case: mostly white paper with thin dark lines, they compress very well and usually stay crisp at 10 KB. A colour face photo at 10 KB becomes small in pixels — which is what forms with this limit expect, since they display it small too.
Tips for a clean 10 KB signature
- Sign with a black or dark blue pen on plain white paper, in good light, without shadows.
- Crop tightly around the signature — extra paper only wastes the 10 KB.
- Choose JPG; PNG is much bigger for photographed signatures.
- Check the form’s minimum size and pixel size too, and set pixels in the Dimensions tab first if they are given.
What to expect at 10 KB
| Image | Result at 10 KB |
