Patu Optimizer – Compress Images to WebP & AVIF

Patu shrinks the images in your WordPress media library by re-encoding them through the Patu optimization API. It works in place and keeps the same format and dimensions, so your URLs never change and it works with every theme and page builder.

• Automatic: new uploads are optimized as they come in, across every generated size (thumbnail, medium, large, full).
• Bulk: optimize your entire existing library from one screen, with a live progress bar.
• Safe: a file is only replaced when the optimized version is strictly smaller (never bigger), a failed optimization never blocks an upload or breaks your site (never broken), and originals are backed up so you can restore any image with one click.
• Private: your API key is only ever sent to patu.dev in a request header.

Two modes:

• Optimize in place (default): re-encodes JPEG and WebP images to a smaller version of the same format. URLs never change, so it works with every theme and page builder. JPEG is the bulk of most libraries‘ weight, and this saves roughly a quarter of its size with no visible quality change.
• Serve next-gen formats (AVIF/WebP): generates modern versions of your images (JPEG, PNG and WebP) and serves them through a <picture> tag, keeping the original as a fallback for older browsers. The biggest savings, and it covers PNG too.

External service

This plugin relies on the Patu image-optimization API to do the actual compression. It is the core function of the plugin and it cannot work without it.

• What is sent, and when: the image files you optimize (on upload if auto-optimize is on, or when you run a bulk optimize / next-gen generate), plus your API key in the X-Api-Key header. A small built-in sample image is also sent when you click „Test connection“. Everything goes over HTTPS to https://patu.dev.
• What comes back: the optimized image bytes. Nothing else about your site (its content, users, or any personal data) is sent, only the image itself.
