How JPG to WebP works
Files are validated, decoded, resized when requested, and encoded by your browser. The application does not send image files to a server, and animated inputs are rejected instead of silently losing frames.
Convert JPEG photos into WebP for the web
Converting JPG to WebP can reduce the weight of photographs used on a website. The amount saved depends on the source, quality and dimensions. The converter starts at 82% quality without resizing, so you can compare formats at the same image size.
Check textured areas, skin and gradients before publishing. Converting an already compressed JPG cannot recover lost details. Use a maximum width if the original is much larger than its display size, and keep JPG when another service specifically requires it.
