I wonder how

Not working atm. Go to Youtube Community and try to save an image.

Great idea. Lossless WebP is generally a superior alternative to Png (except it cannot handle HQs beyond 16k on a side), but when you get served a webp on a web site, there is a 95% chance it is just a Jpg that has gone through another round of lossy compression, a different type, at a lower bit rate = worse quality (fewer fine details).

In an ideal world, the digital master would be encoded as both Jpg/Png and Jxl, and the browser would have an option built in to preference one format over the other. JpegXl is the best new format. Jpeg2000 was decent but I don't think any browsers support it, and it even has a lossless format.

Doesn't work.

TipTop, endlich wieder vernünftige Datei-endungen

Works as intended!

Works as intended. Thank you very much jscher2000

Good

This addon installs easily and does what it says on the tin. I recommend this addon.

Works great so far!

Fantastic! Does what it's supposed to and doesn't get in the way.

Really helpful

Extremely useful and efficient, now I can save an image in it's original jpg or png format, instead of paying 2 conversions jpg-webp then webp-jpg. Should be the default when saving a jpg or png image.

this is one of the most convenient and helpful add-on in the world, it made my life so much easier when using Reddit and is the sole reason I switched to Firefox.

After using this add-on for a long time, I'm only giving it 3 stars, because it's very unclear to me, if it's actually accomplishing anything...? There are lots of sites that keep pushing webp and avif files, even when this add-on is in use, and it feels like the number of those sites is increasing, all the time.

I am so annoyed by the webp format as someone who collects art references on the internet for private use, and no reference program supports webp. Webp is a scourge on the internet and I am glad this plugin exists.

Thank you
