- This 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 🥰開発者の返信
投稿日時: 10ヶ月前Thank 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. 開発者の返信
投稿日時: 1年前Thank 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.開発者の返信
投稿日時: 2年前Thank 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?開発者の返信
投稿日時: 3年前Hi thank you for your review and raising your concern. It could be that you found an avif image that is not yet supported by the Avif detection algorithm. Also in case you have installed other extensions there could be a chance that they would interfere with the conversion. Alternatively a webserver is simply serving jpg, png or another format image while wrongfully adding the .avif extension.
To be sure could you please verify you can see and convert the avif image on this page: https://libre-software.net/avif-test/ ? if not try resetting the addon and try again. If this image works and you can convert it please send the image or a link to the image you are trying to convert. Than I can analyze it and if nessecary update the algorithm.- So while this addon works and does a good job, I find that every time i view any image in a new tab, the current tab will auto scroll to the bottom (as if you pressed End key) and display some random text about the image

I can of course save the image as a jpg/png or whatever that way but I don't always want to do this and this happens whether the image is webp / avif or jpg / png or whatever.開発者の返信
投稿日時: 3年前Thank you for taking the time to write a review. However this addon does not add the random information to the image you write about. From what you wrote it seems to me that you have the add-on "Save webP as PNG or JPEG (Converter)" installed (aswell) that does have this behavior but is unrelated to this add-on - Great and easy to use no problem. I love how you can set the settings for different source file type.
It would be great with this new stupid webp format, if you either had 2 options to save as .gif or as .jpg; or if it detected automatically if it was an image or a gif.
Thnx though - I would have given 5 stars if it converted to PNGs without any quality loss.
When I convert a clean WEBP (no artifacts) to PNG, the resulting file will show artifacts, this shouldn't be happening with a lossless format.
Even if it's technically possible to create a lossy non-standard PNG with reduced file size, that shouldn't be the standard way, if that't the case I suggest an option to change this behavior.
Thank you for creating this plugin!
