Real PNG size reduction
The compressor reduces the number of colors used in the PNG, a technique called color quantization. This can make PNG files much smaller while keeping transparency.

PNG files
First adjust quality, then reduce resolution if necessary. The target size is best effort.
PNG compression uses local color quantization in your browser. Transparency is preserved. If a compressed result would be larger than the original, the original file is kept instead.

Choose the tradeoff
Use more colors for finer gradients and fewer colors for smaller files. A target size can automatically try progressively smaller palettes.
Batch ZIP download
Process several PNG files at once, then download all successful results together in one ZIP.
