How to resize a signature to 20 KB

- Drop the image here. Select or drag your signature file. The 20 KB target is already set.
- Click Resize Image. The tool compresses to under 20 KB, processing entirely on your device.
- Download and upload. Save and submit to your exam or job application form.
Why exam portals need signatures under 20 KB
The 20 KB signature requirement is by far the most common across Indian exam and recruitment portals. SSC, IBPS, NEET, JEE, UPSC (some forms), railway boards, and numerous state PSC portals all use this limit. When lakhs of candidates upload signatures, small file sizes keep infrastructure costs manageable.
At 20 KB you have more room than the 10 KB limit, so signatures generally look clean and legible. The main mistake people make is uploading a photograph of an entire sheet of paper with the signature somewhere in the middle — this wastes the entire budget on blank space.
For the best result, sign on plain white paper with dark ink, crop tightly to just the signature, and run it through this tool. The tool automatically finds the highest quality that fits under 20 KB.
Frequently asked questions
How do I resize my signature to 20 KB for an exam form?

My form needs 20 KB and specific dimensions like 140x60 pixels.
