Overview
This plugin adds WebP and AVIF support for media uploads within the WordPress application.

Modern images will be generated only for new uploads, pre-existing images will only converted to a modern format if images are regenerated. Images can be regenerated with a plugin like Regenerate Thumbnails or via WP-CLI with the wp media regenerate command.

Funktioniert wie beschrieben – Heimvorteil weil von WordPress entwickelt
by lacoste89·1 week ago
Ich nutze dieses Plugin auf allen neuen Webseiten, damit Bilder automatisch nach AVIF konvertiert werden. Es funktionierte bisher immer ohne Probleme, deshalb kann ich es uneingeschränkt empfehlen. Ich hoffe es wird bald auch direkt in den WordPress Core übernommen.

causes an Irreversible damage to your Media library NEEDS and Explicit warning
by faospark·5 months ago
Its been years since I had a terrible experience in this eco system UP UNTIL this one.
The plugin needs to warn users that once youve regenerated post thumbnails and complete entire process is complete even if you deactivate the plugin wordpress will would force you to use tha Avif or webp version of your images. in which a lot of cases will break site. And one would think you can reverse nope that is not case. I had to result to using a back up data base to restore content. I have about 10K images that includes is variable sizes and variable formats on 2 websites . I Have ZERO plans to figure out which is a jpg and png on those let alone re attach them.
There is no official wordpress to manually restore them.
This plugin needs to be further improved.
