About Compress PNG

PNG graphics like logos, screenshots and UI mockups often carry far more colors than they need. Reducing the palette, the same trick used by desktop PNG optimizers, cuts size by 50 to 80% while keeping transparency and crisp edges.

  • Screenshots with gradients may show slight banding at low color counts; try 256 first.
  • Transparency is fully preserved.
  • For photos saved as PNG, converting to JPG or WebP saves far more.

How to use it

  1. 1Drop your PNG files.
  2. 2Choose how many colors to keep; 256 is invisible on most graphics.
  3. 3Download the smaller PNGs.

Questions

Is PNG compression lossless?
Reducing colors is a small, controlled loss. At 256 colors it is invisible on flat graphics and icons.
How much smaller will it get?
Flat graphics typically shrink 60 to 80%; screenshots 40 to 60%.
Are my files uploaded?
No. Everything runs in your browser, so your photos never leave your device.
