How does JPG to WebP conversion work?
JPG to WebP conversion uses modern predictive coding to achieve superior compression. While JPG treats each pixel block independently, WebP uses spatial prediction from neighboring blocks to represent visual data more efficiently. This technology is derived from the VP8 video codec, allowing it to reduce file sizes by up to 30% compared to JPG at the same visual quality level.
Our tool performs this optimization entirely in your browser using WebAssembly. This means that instead of uploading your photos to a distant server, the conversion happens on your own hardware. This approach is not only faster for real-time processing but also ensures absolute privacy and security for your personal or professional images.
