How to resize a signature to 30 KB

  1. Photograph or scan your signature. Sign on white paper with dark ink. A phone photo in good lighting works fine at 30 KB.
  2. Crop to the signature area. Remove excess paper. A small margin is fine at 30 KB — you do not need to crop as aggressively as at 10 KB.
  3. Drop the image here. Select or drag your file. The 30 KB target is preset.
  4. Click Resize Image. The tool compresses to under 30 KB while keeping the signature sharp.
  5. Download and submit. Save and upload to your application form.

When forms ask for signatures under 30 KB

A 30 KB signature limit gives you more room than the strict 10–20 KB limits. This size is common on state-level public service commission portals, banking recruitment forms (PO, clerk, specialist officer), and some university admission applications.

At 30 KB, your signature will look excellent. Even a slightly larger crop with some margin around the signature compresses cleanly at this size. The challenge at 30 KB is almost never quality — it is simply knowing that you need to compress at all, since phone photos typically start at 2–5 MB.

If your form also requires specific pixel dimensions alongside the 30 KB limit, always set the dimensions first and then compress to fit the size limit. The other way around risks the dimension step increasing the file size beyond 30 KB again.

Frequently asked questions

How do I resize my signature to 30 KB?

Drop your signature image into the tool above and click Resize Image. The 30 KB target is already set. The tool compresses to fit and shows you the real file size.

Can I include a little margin around my signature?

Yes. At 30 KB you have enough room for a small margin. Unlike the 10 KB limit where every pixel counts, 30 KB is generous enough for a cleanly framed signature with some breathing room.

Should I scan or photograph my signature?

Either works at 30 KB. Scanning gives more consistent results, but a phone photo in good, even lighting is perfectly fine at this size. Avoid shadows across the signature.

Is my signature uploaded anywhere?

No. All processing happens in your browser. Your signature image stays on your device throughout.
