- Rated 5 out of 5by Sixelona, 2 months agoAs an artist who needs to save images for references and is not a fan of converting WebP just to view them, this app is a life saver. Thank you.

- Rated 5 out of 5by Psythik, 2 months agoSo stupid that you now need an addon to do something that browsers have been able to do natively since the 90s: download an image in its original file format. Why, Mozilla, WHY!? Thankfully this exists, but it shouldn't have to.
- Rated 1 out of 5by Sporitus, 4 months agoВо-первых, эта приблуда просто не работает. А во вторых, конверция происходит не автоматически, а нужно выбирать отдельную менюшку по правой кнопке. Жутко неудобно
- Rated 1 out of 5by Commanden, 5 months agoSomewhere it doesn’t work, it downloads empty five kilobytes!
So guess where it was downloaded and where it was not downloaded. A setup!

posted 5 months agoThe image that you are trying to download is hosted on a server that uses some kind of hotlink protection. (you can only access it when you are active on certain webstites). unfortunately the nature of this addon makes it incompatible with these kinds of protection. instead of the image you got an error response that resulted in the empty file. - Rated 4 out of 5by Dill, 5 months agoThis is very useful! However, I really want this to have an option for "convert and copy to clipboard".
Often, when I copy images onto storyboards, the service will compress larger images, destroying their utility for art.
If this extension had a convert + copy button, I'd be able to easily upload the tiny WebP files instead, which aren't compressed.
I know this works because I can do so manually, with `cwebp` on a terminal window. However, that's kind of slow, and it'd be super nice in this extension!
Anyway, I love this extension. Thanks for helping my workflow 🥰Developer response
posted 5 months agoThank you for the suggestion, I have looked into the matter and unfortunately Firefox is currently not capable of programmatically copying a webp image to the clipboard. Only png and jpeg formats are supported. - Rated 5 out of 5by Firefox user 14855386, 7 months agoVery useful & productive... best converter till now
- Rated 3 out of 5by Firefox user 18390445, 7 months agoDoes not work for saving an animated webp as gif, it only saves the first frame as a still image.
- Rated 1 out of 5by Firefox user 13674814, 9 months agoUSELESS BCS IT CAUSES FIREFOX AND CHROME TO LAG! Use this command instead. I will: &format=original

posted a year agoThank you for using this addon. I have investigated the matter. As far I can verify avif images are converted including those of the site you mentioned. However this site uses a protection to avoid hot linking. To avoid that other websites show images that they are hosting. This causes an issue since it also interferes with the download mechanism of the addon. Fixing this is hard since these kind of measures are site specific. However downloading them reopening and than converting works though this approach defeats the purpose of a single step solution.- Rated 5 out of 5by Firefox user 18176943, a year ago

- Rated 2 out of 5by Bekohanfula, 2 years agoWould never want an extension to save to a less efficient format. Need the other direction, to save to AVIF OR JPEG XL.

- Rated 4 out of 5by Citizen, 2 years agoAbsolutely fantastic for .webp images, but .avif conversion is unreliable currently.

posted 2 years agoThank you for your review, detecting avif is a bit harder than other types of images since avif images can identify themself in multiple ways. Most ways are already tackled but if you found one that wasn't I am happy to hear about it such that it can be added. Do you have an example of an avif image that did not convert?
