About the UPSC signature size
The UPSC asks for a signature of exactly 600 × 200 px, saved as JPG and sized within 20–300 KB. Miss any one of the three — the pixels, the format, or the file size — and the upload box rejects it, which is the wall most people hit. This tool sets all three for you: it crops to the right shape, resizes to the exact 600 × 200 px, and compresses to land within 20–300 KB, in one press.
The UPSC form publishes no fixed pixel size for the signature, only a 20–300 KB JPG; 600 × 200 px (a 3:1 strip) scans cleanly and uploads inside that band.
Need a different job? The image compressorfits any file under a KB limit, and resize & crop gives you free control of the dimensions.
How to make a UPSC signature
- Sign in dark ink on white paper, photograph or scan it, then drop that image onto the box above (or tap to choose it). Drag the crop box — locked to the 600 × 200 px shape — over your signature.
- The output is already fixed to 600 × 200 px, JPG, and will be held within 20–300 KB. There is nothing to set — that is the whole point of the preset.
- Press Apply, then Download. Every step runs on your device; your signature is never uploaded, so it carries no camera, date or GPS data either.

Nothing is uploaded
There is no server to upload to. Your signature is cropped, resized and compressed by this browser with the Canvas API, and the Download button points at the result sitting in your own device's memory. Turn your Wi-Fi off once this page has loaded and it still works — the privacy policy walks through the same check. As a side effect of re-encoding, the file carries no scanner, date or GPS metadata.
Questions and answers
What size should a UPSC signature be?
600 × 200 px, saved as JPG, with the file within 20–300 KB — that is what the UPSC asks for. This tool produces exactly that: it crops to the right shape, sets the size to 600 × 200 px, and compresses to fit the KB limit in one step.
How do I get my signature 20–300 KB?
Drop it in above and press Apply. The tool encodes the 600 × 200 px JPG at the highest quality that still fits within 20–300 KB, so you get a compliant file without fiddling with a quality slider or re-saving over and over. If a very small target cannot be met at the required pixels, the tool tells you rather than handing back a wrong-sized file.
Is the UPSC signature tool free, and does my signature get uploaded?
It is free, with no account or watermark, and nothing is uploaded: your signature is cropped, resized and compressed inside your browser with the Canvas API, so it never leaves your device — turn your Wi-Fi off after the page loads and it still works.
