Your site's photo-heavy pages are probably shipping 40% more bytes than they need to. WebP's modern codec was built specifically to outperform JPEG on the same photographic content you already have.

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
Drop camera JPEGs, stock photos, or exported design JPEGs. Baseline and progressive JPEGs are both accepted, RGB or CMYK.
VP8 compression applies at quality 80 — tuned for photographic content. Block prediction and variable transforms do what JPEG's 8×8 DCT can't.
Each WebP is typically 25–35% smaller than the input JPEG with matching perceptual quality. Filenames preserved with .webp extension.

Note, JPEG is a lossy compression. In addition, you cannot create black and white images with JPEG 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.
Quality, color, EXIF, and when WebP's savings matter most.
