Have you ever considered adding .AVIF export? The results of file size vs compression and image quality are amazing - I highly recommend it (on average, I get -90% compared to PNG, and even WEBP).
Some highlights:
reduces the file size of images by around ~90%
It results in a smaller file size with excellent image quality
open to use and royalty-free
already at 70% browser support
embraces HDR and 12-bit color depth
it’s supported on most modern mobile devices (including Android and iOS)
supports transparency to replace PNG
supports animations to replace GIFs
For more information, I recommend this website - https://avif.io/
We haven’t really considered it as it’s not a format even supported by any of Apple’s platforms – you mention iOS supports it but as I understand it doesn’t, only in third party browsers as I understand. I don’t think we’ll work to add support unless there’s OS level support for it or we see more demand for it.
Hi there, it’s a really good question !
I know that iOS 16 and MacOS 13 already support .avif files (with quick look and in Safari 16).
I’ve made some tests on my side:
Slack doesn’t support it yet, you can send this kind of file but without preview (it considers it as a binary file)
I’ve tested to import it in Sketch and it seems to work (with bitmap conversion I think)
I asked my developers to test it in the assets inside Xcode and the result is: Attempting to lookup a named image ‘home’ with a type that is not a data type in the AssetCatalog
So it’s not yet supported (maybe announced in the next WWDC in June with the new release of Xcode)
Here is the list of supported formats: Asset Catalog Format Reference: Types Overview
AVIF isn’t a great image format. For example, the size limit is 6,780 by 4,320 pixels.
Problem with AVIF is that it’s basically a video format, where each image is encoded like a single frame would be encoded in the video.
I wouldn’t pay too much attention to it. Most image delivery systems can still generate AVIF images on the fly based off e.g. JPEG or PNG, where needed. Not something a graphics-authoring software should be too concerned about.
