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?There are two primary reasons that a WebP image may not be generated:
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.The JPEG image was not uploaded to the Media Library. At this time, WebP versions are only generated for images to the Media Library. WebP versions are not generated for JPEG images that are added to your site in other ways, such as in a template file or the 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.

My website got brokenℭ𝔟𝔟𝔩2024 ལོའི་ཟླ 10 ཚེས 26 ཉིན།1 replyI hope I’m not the single one here with the same problem. My website images now not getting loaded properly. Need to refresh a couple of times to see pictures by picture. It shows that my pictures are missing and look like broken images (404 images not found). Now WordPress automatically .avif not .jpg as I upload my Pictures.P.S. I want to know if is a way do disable/uninstall this crap?
Doesn’t workartyberty2024 ལོའི་ཟླ 10 ཚེས 10 ཉིན།1 replyJust does not do anything. No message. No Error. Just not converting any images. Since there is also not a lot of documentation or community around this plugin I will give up and do this externally.
Don’t Regenerate Thumbnails!mkautsarjuhari2024 ལོའི་ཟླ 10 ཚེས 6 ཉིན།3 repliesDon’t ever regenerate thumbnail with this plugin, it will broke a lot of Images on the frontend because Block editor is still mentioning the old extension rather than AVIF or WEBP. so if you don’t want a lot of your images is broken, don’t use it.Atleast until the problem is fixed.
Lots of Broken Images for Thumbnailsyoursiteneedsme2024 ལོའི་ཟླ 7 ཚེས 18 ཉིན།5 repliesThis plugin worked like it says but it did not change all of the images in the blog posts – only some. So I have a ton of broken images because they are referencing the .jpg and not the .avifI even tried regenrate thumbnails and that did not fix the issue. All of the broken images are the thumnails that are resized. It would be better if it did not automatically delete those images so that at least if it didnt replace them all in the blog posts the old image would still resolve.
Works very wellsigtunasimklubb2024 ལོའི་ཟླ 5 ཚེས 21 ཉིན།1 replyWorks very well for me. Would love to see .png format conversion .གདེང་འཇོག 13 ཡོངས་སུ་ཀློགབྱས་རྗེས་འཇོག་མཁན། & གསར་འབྱེད་པ།“Modern Image Formats” is open source software. The following people have contributed to this plugin.
