Convert JPG to WebP

Converting JPG to WebP is worth doing when the destination matters more than the source. JPG is built for photographs, where small files matter more than perfect fidelity. WebP is built for web images, roughly thirty percent smaller than JPG at similar quality. Which one you want depends entirely on where the image is going next.

This is the single highest value conversion for a website. A page carrying a dozen JPG photographs typically sheds around thirty percent of its image weight moving to WebP at visually identical quality, and every browser in current use reads it. On a slow connection that is often the difference between a page feeling immediate and feeling sluggish.

WebP is the practical upgrade from an older lossy format, typically around thirty percent smaller than JPG at matching quality while adding transparency and animation support. Since your source is already compressed, keep quality high so the second pass does not compound the first.

Your JPG is decoded to raw pixels in this tab and re-encoded once into the new format, so the file passes through exactly one additional compression step rather than several. MozJPEG and OxiPNG do the encoding, the same libraries image tooling relies on, compiled to WebAssembly.
