Why optimise images before uploading?

Oversized images are the number one cause of slow websites. WebP files are typically 25-80% smaller than the same JPG or PNG at equivalent quality, which means faster page loads, better Core Web Vitals, and stronger Google rankings. Run your images through this optimiser before adding them to your site builder, WordPress media library, or online shop.

Is this really private?

Yes. The conversion runs entirely in your browser using your device's own processor - the same way our Mac app works. Your images are never uploaded to a server, never stored, and never seen by us. Close the tab and they're gone.
