so, I have a handful of posts I want to upload, but the highest quality & resolution versions of the images are .webp files with lossy compression. since the site dosn't accept uploads in the .webp format, what the heck am I supposed to do with these?

I know that you're generally not supposed to upload lossy files that were saved as .pngs... but saving them as .jpg is going to mean that the files just have two layers of lossy compression, which seems very obviously worse. I feel like I'm stuck with two bad options here...

bump. still wondering about this.

I'm currently leaning towards uploading them as .jpg and marking them as BVAS and then we can replace them if/when there's native webp support.

Converting to png is a far better option than jpg for this, avoiding the second layer of lossy compression.
It also isn't a better version at source at that point, since no quality is lost.

The only place I know that uses .webp is Twitter and Newgrounds, in which case you should have been using direct-link uploads instead.

As for converting, you can see topic #22506 for possible tips. Otherwise, it would probably be easier to just approach the artist and ask them to export in .png format.

For Newgrounds, can't you change it to a png by changing the extension?

adding to wolfgang's advice: i do know that for some newgrounds posts you can download an image for gif as a png or gif respectively if you "open image in new tab", and change the file extension in the URL from .webp to .png (or .gif for animated webp's)

similar thing for images posted on youtube community posts, except you find the end of the url after the equal sign (for example: =s999-rw-nd-v1) and change it to =s0-v0 and now you have the source image by pure magic!

idk how you deal with xitter uploads besides the typical =orig trick, and i have no idea where you found your posts so this could be entirely useless for your case. in whatever case just follow wolfgang's advice and i hope that whatever i shpleaded about will help you in the future

specifically what I want to upload are the pages of the current chapter of Sinful Pie's Cupcakes comic and while the pages are available on the artist's Twitter directly, all of the images on twitter are the comparatively tiny 1448x2048 85 quality JPEG, compared to the much larger 2733x3866 WEBP hosted on the fanon.co website.
as far as I can tell there's no way to get original png files from th...

nevermind I got the png version.

Every image is automatically converted to webp, but if you change the url you can access the original which can be png or jpg or gif

However the webp format itself is starting to catch on, so some artists may export and upload as webp

Support for that here is in the works

Notably, Clip Studio Paint's recent-ish 3.0 update finally supports natively exporting as webp. Considering how many furry artists use CSP, that could eventually make a big difference.

I think it's going to take people quite a while to get over hating the file format for lack of software support though.

Misskey also uses webp, it's annoying...
Wish the uploader would support it, even ehentai support webp now.

Looks like there is no reason to restict to use webp anymore

Web browser anyway will support it.

Windows 11 latest version supports webp out of box. Even explorer.exe generates thumbnails. Not sure about latest Windows 10. Anyway you can install IrfanView+Plugins to view webp on any retro Windows PC. Works even on Windows XP.

Android starts to fully support webp from android 4.3. Don't know about apple devices.

considering it supports alpha channel, i don't think it won't hurt converting it to png
besides from that, even if i despise webp, it could be supported file format here in foreseeable future, especially its sister format webm is supported.
