Photo & Signature Resizer in KB
Resize a photo or signature to JPEG, using the pixel dimensions and size limit from your application notice.
Before you use this tool
Does my image go to your server?
No. The file is read by your browser, resized locally and made available as a download. There is no upload endpoint.
Can every image be made exactly 20–50 KB?
Not always. A very simple image may stay smaller than the minimum even at maximum JPEG quality. Large dimensions may exceed a small maximum even at low quality. The tool reports the actual bytes and never adds padding bytes to fake a target.
Does a centimetre measurement equal a fixed pixel size?
No. Centimetres depend on resolution/DPI. Use the pixel dimensions or resolution expressly required by the notification; the tool does not guess them.
What happens to transparent areas?
They are placed on a white background when the image is encoded as JPEG. Inspect the preview before using it.
