How to resize a signature to 20KB

  1. Sign your name on plain white paper with a dark pen, take a bright photo, and crop it close to the signature.
  2. Tap the box above and choose the signature image.
  3. The size is set to 20 KB and 140 x 60 pixels. Change the width, height or KB to match what your form asks for.
  4. Check the preview, then tap Download.

Many exam and job application forms ask for a signature image with a small file size and set dimensions. The tool fits your signature inside the width and height you choose without stretching it, then compresses it to your size limit. It does not crop for you, so crop the photo before you start. The 140 x 60 pixel preset is only a common example, so always check the exact size on your form.

Frequently asked questions

What size should a signature image be?

It depends on the form. Some ask for about 140 x 60 pixels and under 20KB, others differ. Read your form carefully and enter its width, height and KB limit in the settings above.

How do I get a clean signature photo?

Use plain white paper and a dark pen, put the paper in good light, and take the photo straight on. Crop away the extra paper before you upload it here.

Why does my signature look wider or taller than expected?

Keep "Keep aspect ratio" ticked so the signature is not stretched. It then fits inside the width and height you set.

Is my photo uploaded to a server?

No. Everything runs inside your own browser, so your photo stays on your device. That makes it suitable for ID photos and signatures.

Is this tool free?

Yes. It is free, needs no sign-up, and has no limit on the number of photos.
