外掛說明
這個外掛能為 WordPress 網站的媒體上傳新增 WebP 及 AVIF 格式圖片的支援。依據預設，網站代管伺服器提供 AVIF 支援，才會產生 AVIF 格式圖片，否則會輸出 WebP 格式圖片。如果主機同時支援這兩種新式格式，便能在 [設定]→[媒體] 中選取輸出格式。請注意，預設僅會為新上傳的圖片產生新式格式圖片，而現有的圖片在重新產生縮圖時才會轉換為新式格式圖片。圖片如需重新產生縮圖，可以使用 Regenerate Thumbnails 外掛，或使用 WP-CLI 的 wp media regenerate 命令。
依照預設，只會針對新上傳的 JPEG 或 PNG 格式圖片會產生新式格式圖片，現有的圖片會保留 JPEG/PNG 格式圖片，而由新上傳圖片所產生的全部尺寸圖片都會是 WebP 或 AVIF 格式圖片。如需變更這個行為，請前往 [設定]→[媒體] 啟用 [同時輸出後援格式圖片]，啟用這項設定後上傳的圖片，每個產生的圖片尺寸，都會同時產生 JPEG、WebP 或 AVIF 格式圖片。請注意，一樣只有啟用這項設定後新上傳的圖片才會套用這項設定。
這個外掛就是之前的 WebP Uploads 外掛。

There are a lot of issues that have led me to uninstall in production environment.
It is not able to generate webp files with less weight than jpeg.
Regenerate Thumbs can cause a serious problem if you check the wrong input.
If you choose to save copy of original file, it will not generate the WEBP.
Thanks for trying anyway WP team.
PD: I think it is time to contribute to something that should be CORE for WP.

the images are compressed correctly but the type remains image/jpeg and I don’t know if this can lead to future problems

I 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?

Just 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 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.

This 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 .avif
I 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.
