WebP AVIF Pro converts and compresses your media library images to WebP or AVIF, right on your own server. No subscription, no credits, no image ever sent to a third party: your files stay with you.

Two delivery modes to choose from: replace the original (with backup and restore) or keep the original and serve the next-gen format only to compatible browsers. Beyond compression, the plugin generates AI ALT text in five languages, emits ImageObject schema, adds anti-CLS dimensions and renames your files with an SEO template. Process in batches, in the background via WP-Cron, or from the command line with WP-CLI.
