Local PNG optimization

Compress PNG Images Online

Reduce PNG file size locally while keeping PNG output lossless.

Optimize PNG images

Your image stays on your device. PixPact does not upload image files for compression.

What to expect

  • PNG output uses lossless optimization.
  • The quality slider is disabled for PNG because it does not apply a lossy quality setting.
  • Your image stays on your device while it is processed.

How to use it

  1. Choose a PNG image.
  2. Keep PNG selected as the output format.
  3. Download the optimized PNG when the task is complete.

Common questions

Will PNG output always be smaller?

No. Lossless optimization removes avoidable data, but the result depends on the original PNG.

Why is the quality slider disabled?

PNG output in PixPact uses lossless optimization rather than a visual-quality setting.
