How this tool works

What it does

Resizes a signature to the pixel dimensions you set and compresses it toward 20 KB, then reports the achieved size and dimensions.

Dimensions and background

Set width and height and how the signature fits the box. Keep a white JPG background, or choose PNG for transparency.

Privacy

Your signature is processed on your device. Nothing is uploaded, and re-encoding strips EXIF and GPS metadata. Note that print DPI is not written by the browser canvas; control size in pixels.

Signature Resize to 20 KB in your browser

This tool resizes a signature to specific pixel dimensions and compresses it toward 20 KB, all in your browser. It is for forms that ask for both a size and a file-size limit.

Set the width, height, and fit, choose a background, and the tool reports both the achieved dimensions and the achieved file size. It compresses toward 20 KB rather than guaranteeing an exact 20 KB.

How to use Signature Resize to 20 KB

  1. Add your signature image with the upload box or by dragging it in.
  2. Set the width and height in pixels and choose how the signature fits the box.
  3. Keep white JPG or switch to PNG, set the 20 KB target, then click Process.
  4. Check the achieved dimensions and size in the panel, then click Download.

Frequently asked questions

Will the signature be exactly 20 KB?

No. The tool compresses toward 20 KB and reports the size it reaches, keeping the largest result at or under 20 KB where possible.

Can I set exact pixel dimensions?

Yes. Enter a width and height and choose a fit mode. The panel shows the achieved dimensions alongside the file size.

Can I set the print DPI?

No. The browser canvas does not write print DPI into the file, so dimensions are controlled in pixels. Choose the pixel size the form expects.

Is my signature uploaded?

No. Resizing and compression happen in your browser, so the signature never leaves your device.

Should I use JPG or PNG for a signature?

JPG on a white background is smallest and suits most forms. Use PNG if you need a transparent background.
