## Beskrivning

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](https://wordpress.org/plugins/regenerate-thumbnails/)
or via WP-CLI with the `wp media regenerate` [command](https://developer.wordpress.org/cli/commands/media/regenerate/).

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).

_Detta tillägg hette tidigare WebP Uploads._

### Hur kan jag bidra till tillägget?

Bidrag är alltid välkomna! Läs mer om hur du kan engagera dig i [Handboken för Core Performance-team](https://make.wordpress.org/performance/handbook/get-involved/).

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

Det finns två huvudsakliga anledningar till att en WebP-bild kanske inte genereras:

 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. JPEG-bilden laddades inte upp till [Mediabiblioteket](https://wordpress.com/support/media/).
    För närvarande genereras WebP-versioner endast för bilder till mediebiblioteket.
    WebP-versioner genereras inte för JPEG-bilder som läggs till på din webbplats på
    andra sätt, t.ex. i en mallfil eller i [Anpassaren](https://wordpress.com/support/customizer/).

### With the Modern Image Formats plugin activated, will the plugin generate JPEG and WebP versions of every image that I upload?

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.

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.

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

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.
