Resize Image to 20 KB
A 20 KB limit is tight, and it's the one signature uploads usually have. Add your image below and the tool compresses it to stay under 20 KB, with the final size shown before you download.
Tip for better results
If a photo looks rough at 20 KB, enter the smaller pixel size your form asks for first. Fewer pixels leave more room for quality in the same 20 KB, so a 200 × 230 photo stays far clearer than a full-size one.
Forms that often use this size
| Exam | Item | Dimensions | File size |
|---|---|---|---|
| SSC | Signature | 140 × 60 px | 10–20 KB |
| UPSC | Signature | 140 × 60 px | 10–20 KB |
| Banking | Signature | 140 × 60 px | 10–20 KB |
| NDA | Signature | 140 × 60 px | 10–20 KB |
| UPSSSC | Signature | 140 × 60 px | 10–20 KB |
| UPPSC | Signature | 140 × 60 px | 5–20 KB |
These are common values and can change. Always confirm the exact size and KB limit in your official notification before uploading.

Frequently asked questions
How do I resize an image to 20 KB?
Add your image above. The 20 KB limit is already filled in, so enter the width and height your form asks for, check the final size and download the JPG.
Will the image be stretched to reach 20 KB?
No. The tool lowers the JPG quality first, so the shape stays the same. If the form needs a different shape, the image is trimmed to fit, and you can move the crop box to choose what stays.
What if it can't reach this size?
Very detailed or very large images may need smaller pixel dimensions. The final dimensions and file size are shown before you download, so check them against your form.
Is my image uploaded anywhere?
No. Everything runs in your browser, so your photo or signature never leaves your device. It's free, with no sign-up and no watermark.
