PNG (Portable Network Graphics)
PNG is a lossless image format that supports transparency. It is ideal for logos, screenshots, illustrations and images with text, but photos in PNG are larger than in JPG.

How to use Compress PNG
- Select your images or drag and drop them onto the page.
- Set the options in the panel.
- Click the button to process every image.
- Download the result, or a ZIP file for several images.
A PNG stores every colour exactly, which makes files heavy. Most graphics, however, use far fewer colours than they could. The compressor reduces the palette to at most 256 carefully chosen colours with gentle dithering, then rewrites the file with maximum compression. The result typically weighs 50 to 70% less and looks the same.
Transparency is fully preserved, so logos and icons keep their clean edges on any background. For photographs, JPG or WEBP will always give smaller files than PNG.
