Convert JPG images to WebP for 25 to 35 percent smaller files with no visible quality loss. Batch conversion runs in your browser — nothing is uploaded.
Convert JPG images to WebP locally — nothing is uploaded. WebP is a modern format that is typically 25 to 35 percent smaller than JPG at the same visual quality, which makes pages load faster.
Smaller images are the single biggest web-performance win. Serving WebP instead of JPG cuts bandwidth and improves Core Web Vitals — and therefore both SEO and ad viewability — with no visible quality loss. Convert your photos before uploading them to a site or CMS that supports WebP.
WebP supports both lossy and lossless compression and transparency. It is now supported by every major browser, though a few older desktop apps still are not — for those, keep a JPG or PNG copy. Pick a quality level that balances size against detail; for most photos a high setting is indistinguishable from the original.
To go back the other way, use the WebP to JPG converter; to compress images of any format, use the image compressor.
