Why should I convert images to WebP?

WebP files are typically 25–35% smaller than JPG or PNG at the same visual quality, so your pages load faster — improving Core Web Vitals, SEO, and bandwidth costs.

Can I convert many images at once?

Yes — drop a whole folder and convert up to 100 images in one batch, each with a readout of exactly how much smaller it became.
