Just as a side note: I found a WebP file on a website I wanted to share in Slack. I downloaded it and tried to convert it to JPEG to put in Slack (as it didn't seem to support it). It was much harder than it should have been to convert the image type. Never had such an issue with a JPEG, PNG, GIF, etc.

So how did you end up doing it? It’s indeed not super easy on macOS, I imagine you’d use a website to convert it or get ImageMagick through brew. On Windows I wonder if the photo app supports it, in which case you’d hopefully just double click the image and then save a copy, but unfortunately I cannot try that right now. I think ideally Slack should be able to convert on the fly, just like creating low quality versions for thumbnails. It’s a paid service after all! But that doesn’t change the current predicament. I personally too use PNG for graphic, and JPG for pictures even today, despite Lighthouse suggesting I add WebP extras. It’s just so much easier and more portable with so little to gain by doing it.

I would mostly agree with you, but these days I'm easily pleased when these types of services do the simple things well. They are only really incentivized to support the most popular image types anyway. > I personally too use PNG for graphic, and JPG for pictures > even today, despite Lighthouse suggesting I add WebP > extras.

To the average user, the difference between 90kB and 80kB images is not worth losing sleep over. If you were serving that image several million times a day I could imagine it's slightly more pressing. As an aside I sometimes use my Sony Mavica (floppy disk camera) and that thing outputs valid JPEGs that I can upload to anywhere. (I use it as mostly a joke, but I also love the idea of having a limited number of pictures and keeping old tech going.) [1] https://ezgif.com/webp-to-jpg https://ezgif.com/webp-to-jpg

You'll be happy to know that FFmpeg will happily convert a WebP file to a PNG and vice versa. The reason being that WebP is a single frame WebM. Silly, yes, but it works.

I don't have a Mac, but you can download it prebuilt directly from Google: https://developers.google.com/speed/webp/docs/precompiled https://developers.google.com/speed/webp/docs/precompiled And it should also be available from both Homebrew and MacPorts. To convert a .webp image, use dwebp foo.webp -o foo.png

  I don't understand why they haven't put this into a Linux package? If you want it to get widely adopted, surely you should make it easier for software to add dependencies on your image type. For example one of my projects currently depends on libjpeg and libjpeg-dev for building.

This has thrown me off too, I drag a lot of images from my browser to my desktop when browsing. WEBP files dragged from Mac chrome just fail silently and never appear on the desktop so now I have to pay extra attention every time. Although I’m sure the server owners enjoy the benefit, but if it doesn’t work Like a jpeg and I have to change my workflow for an image format then it sucks for the user.
