Overview
Images are the heaviest thing on your pages, and PageSpeed keeps telling you to "serve images in next-gen formats." Image Optimizer does it entirely on your own server: JPG and PNG convert to WebP locally via cwebp, Imagick or GD (with graceful fallback), so there's no external API, no per-image fees and no rate limits, ever.
The storefront emits proper `<picture>` tags with a WebP source and JPEG fallback plus native `loading="lazy"`, so every browser gets the best format it supports. Convert the back catalogue in bulk, keep new uploads converted via cron, or script it with the CLI.
Features
Every capability earns its place: built to solve a real merchant problem, not pad a feature list.
JPG/PNG → WebP on your own server via cwebp, Imagick or GD, no external service in the loop.
Unlike API-based optimizers there's nothing metered: convert a million images for free.
