How it works

Use this PNG compressor when an upload form has a strict 100 KB file-size cap. The target is prefilled to reduce trial and error.

  1. Upload your PNG image.
  2. Keep the output target at 100 KB.
  3. Process the image and review the estimated file size.
  4. Download the compressed file.

Tips for the best result

  • Photos usually compress best as JPG or WebP.
  • Flat graphics and screenshots may look cleaner as PNG.
  • If the target is very small, reduce pixel dimensions before reducing quality.
