PNG handles transparency perfectly but ships megabytes when you only needed kilobytes. WebP keeps the alpha channel and cuts the payload — often by half.

Supports PNG
Drag one or many PNG files. The tool auto-detects whether your PNGs have an alpha channel and preserves it in the output.
PNGs with solid color, text, or UI content encode as lossless WebP (typically 30–40% smaller). Photographic PNGs encode as lossy WebP at quality 80 (50–70% smaller).
Output files carry the alpha channel, original dimensions, and color profile. Filenames keep their base with .webp extension.

Portable Network Graphics
Requires libpng-1.0.11 or later, libpng-1.2.5 or later recommended. The PNG specification does not support pixels-per-inch units, only pixels-per-centimeter. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).
Weppy image format
Requires the WEBP delegate library. Specify the encoding options with the -defineoption See WebP Encoding Options for more details.
