WebP Converter
Convert any image to WebP in bulk, with a live before/after file size comparison, entirely inside your browser.
Why convert to WebP?
WebP is a modern image format that typically produces smaller files than JPG or PNG at an equivalent visual quality, while still supporting transparency. It's supported by all major modern browsers, making it a strong default for images served on the web.

Features & benefits
Why this runs entirely in your browser
The conversion uses the browser's own Canvas API to redraw and re-encode the image locally, so the original file never leaves the device — no upload, no server-side processing.
Common uses
Reducing image weight on a website for faster page loads, converting a batch of product photos to a modern format, or shrinking a GIF-turned-image down to a smaller static WebP.
