Convert a JPG to WebP for a smaller website asset. This is a lossy re-encode by default, trading a bit of additional visual detail for a meaningfully smaller file — the right trade for images going onto a page, not for a source file you'll keep editing or printing.
Encoding happens on your device
The WebP encoder runs as WebAssembly directly in your browser. Nothing about the image is sent to a server — the JPG is decoded, re-encoded, and handed back to you locally.
FAQ
Why convert JPG to WebP?
WebP typically produces a smaller file than JPG at a similar visual quality, which is the whole reason it exists. For a website, that's faster page loads and less bandwidth. Actual savings vary by image, but a meaningful reduction on photographic content is the norm.
Am I losing quality on top of what the JPG already has?
A little, yes. This re-encodes the image with WebP's own lossy compression, and the JPG's existing compression artifacts are already baked into the pixels it starts from. Two lossy passes are never as clean as one, but at web viewing sizes the difference is rarely visible. For the best result, convert from the original source rather than a JPG that's already been compressed hard.
Will WebP work everywhere I need it to?
Every modern browser displays WebP natively, so for a website it's safe. Where it can still cause friction is outside the browser: some older desktop software, certain email clients, and some upload forms (print services, older CMS platforms) don't accept it. Keep a JPG on hand if you need to hand the file to something other than a browser.
Does this affect transparency or EXIF data?
A source JPG has no alpha channel, so there is nothing to preserve on that front. Camera EXIF metadata (orientation, camera model, GPS if present) is not carried over to the WebP output — the image itself is unaffected, only the metadata is dropped.
