Compress PNG
Shrink PNG files by reducing colours, and keep the transparent background.
Runs in your browser · nothing uploaded
Lossless keeps every pixel but can only re-pack the file, so savings are small. Reduce colours builds a palette of the colours your image uses most and often makes screenshots, logos and graphics less than half the size; photos with smooth gradients may show banding at low colour counts. Transparency is kept.
How to use it
- 01Choose Reduce colours (and how many) or Lossless only.
- 02Add your PNG.
- 03Download the smaller PNG; the saving is shown.

About this tool
Reduce colours picks the 256 (or fewer) colours your image uses most and saves an indexed PNG, the same idea used by popular PNG optimisers. Screenshots, logos, charts and illustrations often shrink to less than half with no visible change. Photos with smooth gradients can show banding at 64 colours or fewer; try 256 first.
Lossless only re-saves every pixel exactly. It can only re-pack the data, so the saving is small, and sometimes there is none; the tool tells you if your file is already smaller. Transparency is kept in both modes.
Your image is processed in your browser and never uploaded; close the tab and it's gone. For photos, converting to JPG or WebP usually saves far more.

Questions
Will my PNG lose quality?
Lossless only keeps every pixel. Reduce colours keeps up to the number of colours you choose; at 256 the change is rarely visible in screenshots and graphics.
Is the transparent background kept?
Yes, in both modes.
Why is my photo PNG still large?
PNG suits graphics, not photos. Convert a photo to JPG or WebP for a much smaller file.
