Signature Resize Online Free: 10-20 KB for SSC, IBPS, PAN and NEET

Quick answer on signature resize: Photograph your signature on white paper, add it to the free tool below and download: it comes out as a crisp black-on-white JPG between 10 and 20 KB, which is the signature range for SSC, IBPS, SBI and RRB forms. For other forms, change the numbers: NEET and JEE accept 4–30 KB, the online PAN form up to 10 KB, and UPSC up to 100 KB. If the form gives exact pixels or centimetres, set those too.

The signature is the upload that fails most often, because a photo of a signature is mostly grey paper: too big in colour, too small (under the minimum) when cropped tight, and blurry if a compressor crushes it. The tool below turns the paper pure white, keeps the ink sharp and hits the KB range, all on your own device.

Signature resizer: crisp black ink, exact KB
Choose one photo or many. Each one is compressed to the size you set, as a JPG, keeping as much sharpness as the limit allows. Everything happens on your phone or computer: nothing is uploaded, no sign-up, no watermark, no daily limit.

Your photos never leave this device. Close the page and they are gone.

How to Resize a Signature in 4 Steps

  1. Sign on plain white paper with a black gel or ball pen (blue only if the form allows it). Sign as you normally would; some forms reject signatures in capital letters.
  2. Photograph it flat in daylight, from directly above, without your shadow. Crop close to the ink in your phone's photo editor if you can.
  3. Add it to the tool above. “Black and white” is already ticked and the range is set to 10–20 KB. For a fixed size, choose pixels (IBPS: 140 × 60) or cm (SSC: 6 × 2 cm).
  4. Download the JPG and upload it. The result line confirms the KB and pixel size.

Too Small? Why a Signature Can Be Under 10 KB

A clean signature at 140 × 60 pixels has very little in it: even at the highest JPEG quality it is often only 3–6 KB, and the portal says “file size less than minimum”. Making it blurry or adding colour is the wrong fix. The tool instead adds an invisible blank block inside the file to reach the minimum, without changing the picture. In our test, a 140 × 60 signature came out at 10.1 KB at 95% quality, accepted by a 10–20 KB form, and a full-size signature in black and white fitted in 9.7 KB at 838 × 377 pixels for a form with a 10 KB maximum.

Is It Safe to Resize My Signature Online?

Your signature, together with your photo and ID number, is what someone needs to fill in forms in your name. Most resizer sites upload the image to their server. This one never does: the image is opened, cleaned and compressed inside your browser, and disappears when you close the page.

Frequently Asked Questions: Signature Resize

How do I resize my signature to 10–20 KB?

Add the photo of your signature to the tool above; it is already set to 10–20 KB in black and white. Download the JPG and upload it.

How do I resize a signature to 140 × 60 pixels?

Choose “Set width and height in pixels” in the tool and type 140 and 60. That is the IBPS, SBI and RRB signature size; the tool pads the file to 10 KB if needed.

What is 6 cm × 2 cm in pixels for the SSC signature?

About 236 × 79 pixels at 100 dpi, or 472 × 157 at 200 dpi. Choose cm in the tool, enter 6 and 2, and pick the dpi.

Can I sign in blue ink?

Only if the form allows it. Most Indian exam forms ask for black ink; the tool's black-and-white setting makes blue ink black anyway, which is what those forms want.

How do I resize a signature on my phone?

Open this page in your phone's browser, tap Choose photos and take a picture of your signature or pick one from the gallery. Everything runs on the phone.
