WebP is Google's modern web image format and often delivers 25-35% smaller files than JPG at comparable quality. That speeds up websites and saves bandwidth - which is exactly why Google recommends WebP for web images. For a JPG photo, lossy WebP is the right fit.
The image is painted onto a local canvas and encoded as WebP; the quality slider controls the balance of size and sharpness. A JPG has no transparency, so the result is an opaque WebP.
Everything runs in the browser - no upload, no account, even offline. Your photos never leave your device, unlike online converters that upload your images to third-party servers.

Limitations: WebP here is lossy (like JPG); the quality slider controls compression. Very old browsers or programs may not open WebP - then JPG is the more compatible choice. Animated inputs are converted as a single frame. Embedded metadata such as capture date, camera and GPS location does not survive the re-encode - only the image orientation is baked into the pixels beforehand.
No. The conversion runs entirely locally in the browser - even in airplane mode.
At equal quality usually 25-35% versus JPG, depending on the image.
WebP here is lossy; at 80 the difference is usually invisible. Higher = larger and sharper.
