Compress PNG
Free · Local · No loginCompress PNG images while keeping PNG output and transparency support.
PNG is compressed losslessly — zero quality loss. JPG & WebP use quality-based compression; raise quality to keep more detail.
Compress PNG files in your browser
PNG compression on Fernpix keeps PNG output (including transparency) instead of forcing a JPG conversion. Ideal for UI graphics, logos, and screenshots that must stay PNG.
Popular use cases

How to use
- 1
Drop PNG files into the workspace.
