Beschreibung

This plugin adds WebP and AVIF support for media uploads within the WordPress application. By default, AVIF images will be generated if supported on the hosting server, otherwise WebP will be used as the output format. When both formats are available, the output format can be selected under Settings > Media. 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.

By default, only modern image format sub-sizes will be generated for JPEG or PNG uploads – only the original uploaded file will still exist as a JPEG/PNG image, generated image sizes will be WebP or AVIF files. To change this behavior, there is a checkbox in Settings > Media „Output fallback images“ that – when checked – will result in the plugin generating both the original format as well as WebP or AVIF images for every sub-size (noting again that this will only affect newly uploaded images, i.e. after making said change).

This plugin was formerly known as WebP Uploads.

I’ve activated the Modern Image Formats plugin, but WebP images are not always generated when I upload a JPEG image. Why?

Es gibt zwei Hauptgründe, warum ein WebP-Bild nicht erzeugt werden kann:

  1. The Modern Image Formats plugin has identified that the WebP version of the uploaded JPEG image would have a larger file size than the original JPEG image, so it does not generate the WebP version.
  2. Das JPEG-Bild wurde nicht in die Mediathek hochgeladen. Derzeit werden WebP-Versionen nur für Bilder in der Mediathek erstellt. WebP-Versionen werden nicht für JPEG-Bilder erstellt, die auf andere Weise zu deiner Website hinzugefügt wurden, zum Beispiel in einer Template-Datei oder im Customizer.

Wenn das Plugin Modern Image Formats aktiviert ist, erzeugt es JPEG- und WebP-Versionen jedes Bildes, das ich hochlade?

By default, the Modern Image Formats plugin will only generate WebP versions of the images that you upload. If you wish to have both WebP and JPEG versions generated, you can navigate to Settings > Media and enable the Generate JPEG files in addition to WebP option.

compression?

Good plugin, but no option to set the WebP compression value. What compression is used here?

causes an Irreversible damage to your Media library NEEDS and Explicit warning

15. Oktober 2025
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.

Good one

Nice light plugin, does what is says.

Easiest way to get AVIF images

25. Juni 2025
I love that it doesn’t force you to generate all image sizes of the original format and avif, but just does the avif (or webp if you choose that). It would be really nice if it could rework old images, and maybe even modify the database to match. But still, excellent and should be installed first thing on all new WP sites in my opinion.
