The problem

Images are the heaviest part of a website. Traditional optimizers process on the server (Imagick/GD, CPU/RAM) or upload your images to an external SaaS.

How it's solved

WebP/AVIF conversion entirely in the admin browser via WASM: the server is unaffected, there are no dependencies, and images never leave your WordPress. Reusable profiles, a bulk processor, responsive <picture> replacement and hashing so nothing is reprocessed.
