Signature Resizer for Government Forms

Resize a signature to 10KB–20KB (or any required range) for SSC, IBPS, UPSC, Railway RRB, and PAN forms — auto-crop, clean up, and compress in one step.

🔒 No upload — 100% private, works fully offline in your browser.

Drag & drop a signature photo

A clean scan or photo on plain white paper works best.


Higher sensitivity whitens more of the background but can thin out faint ink.

Exact KB window

Targets both a minimum and maximum file size — many portals reject files that are too small, not just too large.

Auto-crop & clean

Trims whitespace automatically and can whiten paper background for a crisp scan look.

100% offline

Your signature is never uploaded — everything runs locally using the Canvas API.

Photo vs. scanned signature

A flatbed scan on plain white paper usually gives the cleanest result. A phone photo works too if it's taken in good, even light directly above the page to avoid shadows and blur — use the "clean background" option to whiten the paper and boost ink contrast.

Meeting a minimum file size

Tiny, simple signatures can compress to just a few KB even at full quality — below some portals' minimum. When needed, this tool adds a very light texture to the image to bring the file size up into the required range without changing its pixel dimensions.

Frequently asked questions

How do I resize my signature for SSC?

Upload a clear photo of your signature (or draw it directly), choose the SSC preset (140×60 px, 10–20 KB), and click Process. The tool auto-crops whitespace, resizes to the exact dimensions, and compresses it to land inside the 10–20 KB range.

Why is my signature file being rejected on the form portal?

Most portals reject signatures that are the wrong pixel dimensions, or outside an allowed file-size range (both too large AND too small can be rejected). This tool targets both the exact dimensions and the minimum/maximum KB range together.

Should I upload a photo of my signature or a scanned copy?

A flatbed scan on plain white paper usually gives the cleanest result. A phone photo works too if it's taken in good, even light directly above the page to avoid shadows and blur — use the "clean background" option to whiten the paper and boost ink contrast.

Are the UPSC/SSC size specs guaranteed to be current?

Exam authorities occasionally revise their specifications. Presets here reflect commonly published specs at the time of writing — always verify against your official notification before submitting, and use the Custom option if requirements differ.
