Is WebP better than JPEG?

For web use, yes. WebP produces 25-35% smaller files at equivalent visual quality and supports transparency. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP. The only reason to prefer JPEG is compatibility with very old systems or email clients.

Does this tool upload my images?

No. All processing happens in your browser using the HTML5 Canvas API. Your images are never sent to any server. The tool works offline once loaded.

AVIF offers even better compression than WebP but isn't yet supported in all browsers. Browser support for AVIF is still expanding. For now, WebP offers the best balance of compression and compatibility. The tool currently supports WebP, JPEG, and PNG.
