Your images are processed on your own device and are not sent to our servers, so we never see or store them.
Smaller images make pages load faster, which helps your visitors, your PageSpeed results and your bandwidth bill.
Large PNG and JPG files are one of the most common reasons a page feels slow, and they often decide your Largest Contentful Paint (LCP), one of Google's Core Web Vitals. WebP versions are usually 25-35% smaller, so pages load sooner, especially on mobile data.
JPEG can't store transparent areas, but WebP can (8-bit alpha transparency). Transparent PNG logos, icons and illustrations keep their clean edges when converted to WebP.
Many online converters upload your files to their servers to process them. This one does the work locally in your browser using the Canvas API, so client photos and unreleased product shots stay on your device.
