About this tool

Compress JPG to 15KB

Many websites and application forms only accept images under 15 KB. This tool shrinks your photo below 15 KB automatically: it finds the highest JPG quality that fits, and only reduces the dimensions if the quality alone isn't enough. That keeps the picture as sharp as possible.

A 15 KB limit is common for signatures on job and exam application forms. If your form also sets a minimum size or exact dimensions, click Change and enter them, or use one of the exam pages below.

Everything happens in your browser, so your photo is never uploaded. It works on Android, iPhone and desktop.

  • Always under 15 KB

    The file is checked against 15 KB before you download it.

  • Best quality that fits

    Quality is lowered only as much as needed, then the size if necessary.

  • Any image format

    Upload JPG, PNG or WebP. You get a JPG that every form accepts.

  • No upload

    Works offline once the page has loaded. Your photos stay on your device.
