PNG to WEBP Converter · runs entirely on your device
This tool converts PNG images to WEBP directly in your browser. The file is decoded onto an HTML canvas and re-encoded as WEBP, so it never touches a server and the conversion finishes in milliseconds.
WebP produces significantly smaller files than JPG or PNG at the same visual quality, which improves page-load performance and Core Web Vitals.
PNG is a lossless raster image format that supports up to 16.7 million colours plus a full 8-bit alpha channel for transparency. It uses DEFLATE compression, so re-saving a PNG never degrades quality.
Best for: Logos, icons, screenshots, line art, and any image that needs sharp edges or a transparent background. Trade-offs: Files are much larger than JPG or WebP for photographs, and PNG cannot store animation.
WebP is a modern image format from Google that offers both lossy and lossless modes plus alpha transparency and animation. At matched quality it is typically 25–35% smaller than JPG or PNG.
Best for: Web images where page-load speed and Core Web Vitals matter; it replaces both JPG and PNG in one format. Trade-offs: Older software and some social platforms still do not accept WebP, so a JPG or PNG copy is sometimes needed.
