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 JPG, JPEG, PNG, WEBP, SVG, GIF, HEIC, HEIF, BMP, TIFF, HDR, JP2, RAF, PSD, CR3, DNG, APNG, AVIF, AVI, ESP, EXR, J2C, J2K, JXL, PFM, PNM, PPM, PSB, SGI, MPEG, PDF
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.
