Can't save images as .PNG on some sites - only as .WEBP

Posted

I can't save some images as .PNG for some sites I use. (ex. any of the wikis on fandom.com) .WEBP images are completely useless to me - my version of Photoshop (CC 2018) can't even load them. It still saves as .WEBP even if the URL itself says it's a .PNG file. I don't want to go through the hassle of having to convert them every time I want to download an image, I just want it like it was before where I could just download it as a .PNG file. Is there a way to disable saving images as WEBP, like an extension or something in about:config?

hi, you could try the tweak discussed at https://old.reddit.com/r/firefox/comments/alm5pq/firefox_image_saves_into_chrome_html_document_webp/efi7smg/

Doesn't work for the site I used as an example. However, I did find that removing "image/webp" from "network.http.accept.default" in the about:config page did solve the problem.

I tried both solutions here but neither of them worked! Firefox is still saving as .webp

If the website only supports WebP images then you are out of luck.

You can remove "image/webp," from the accept prefs to prevent getting WebP images send by the server.

  • image.http.accept = */* (default: image/webp,*/*)
  • network.http.accept.default = text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 (default: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8)
