About Photo to 20KB

Photo to 20KB compresses a photo to a target file size — 20KB by default or any size you set — at the best quality it can manage for that limit. It is for forms and portals that cap the upload size of a photo.

Many official forms reject files over a strict size. Compressing to that exact target in the browser meets the limit without uploading your photo anywhere.

How to use

Step by step

  1. Drop the photo you need to shrink.
  2. Set the target file size, or keep the 20KB default.
  3. The tool compresses toward that size at the best achievable quality.
  4. Check the result and the final size.
  5. Download the compressed photo.

Best practices

Tips for best results

  • Check the form’s exact size limit and accepted format before uploading; this tool cannot guarantee acceptance.
  • Crop to just the needed area first so the limited bytes are spent on what matters.
  • Very small targets soften detail; use the largest size the form allows.
