Fills transparent areas (JPG has no transparency).

The size is preset to 20 KB in JPG. The tool keeps the best quality that fits, and only makes the image smaller in pixels if it has to. Images already under the limit are left untouched.

Images are resized locally in your browser. Nothing is uploaded or stored.

How to Resize Your Signature

  1. Sign on plain white paper with a black or dark blue pen, then take a photo or scan it.
  2. Drop the image into the box above. The target is 20 KB; tap 10 KB if your form asks for less.
  3. Press Resize Images and download your signature.

Tips for a Clean Signature Image

  • Crop tightly around the signature before uploading. Empty paper wastes space and makes the signature look tiny on the form.
  • Use daylight or a bright lamp and avoid shadows from your phone or hand.
  • Hold the camera straight above the paper so the signature isn't slanted.
  • Exact pixel size required? Some forms specify both pixels and KB. Set the pixels in Image Resizer first, then come back here to reach the KB limit.

Photo and Signature Together

Most forms also ask for a photo. Resize it with Resize Image to 20 KB or Resize Image to 50 KB, depending on the limit.

Frequently Asked Questions (FAQs)

How do I resize my signature to 20 KB?

Take a photo or scan of your signature, drop it on this page and press Resize Images. The target is already set to 20 KB in JPG.

How do I make my signature 10 KB?

Tap the 10 KB button before pressing Resize Images. A tightly cropped signature on white paper easily fits in 10 KB.

Should I use a scan or a phone photo?

Either works. A scan is cleaner, but a phone photo taken in good light, straight above the paper, is just as good once cropped.

Which format should my signature be?

Most forms ask for JPG, which is the default here. Choose PNG only if the form specifically asks for it.

Are my photos uploaded to a server?

No. The photo is compressed inside your browser on your own device. It is never uploaded, so the tool is safe for ID photos and personal documents.
