Google ranks faster sites higher. WebP trims JPGs by a third at equivalent quality. For every 1 MB of JPG on your page, WebP gives you back roughly 300 KB of LCP headroom.

Select individual JPGs or an entire folder's worth of site assets. Progressive JPGs and CMYK JPGs both work.
WebP's VP8 lossy codec runs on decoded pixels. Quality defaults to 80 — the Google-recommended sweet spot for web imagery.
Output files are typically 25–35% smaller than the input JPGs with no perceivable quality change. Filenames preserved with .webp extension.

Note, JPG is a lossy compression. In addition, you cannot create black and white images with JPG nor can you save transparency. Requires jpegsrc.v8c.tar.gz. You can set quality scaling for luminance and chrominance separately (e.g. -quality 90,70). You can optionally define the DCT method, for example to specify the float method, use -define jpeg:dct-method=float. By default we compute optimal Huffman coding tables. Specify -define jpeg:optimize-coding=false to use the default Huffman tables. Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image with jpeg:size, for example -define jpeg:size=128x128. To restrict the maximum file size, use jpeg:extent, for example -define jpeg:extent=400KB. To define one or more custom quantization tables, use -define jpeg:q-table=filename. These values are multiplied by -quality argument divided by 100.0. 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.
