| Description | See comments for discussion of formats.
For video, we should support metadata detection (width, height, length) for whatever container format becomes common. Old text: WebP now offers better lossless and lossy compression than PNG and JPEG. As Microsoft have switched to Chromium, the only hold-out browser without WebP support is Safari. Once Safari has added support, we can put ourselves all-in with WebP for any non-vector images. Update tut_webapp to reference the spec. |
| Steps to reproduce | |
| Additional information | Other formats are around which are not supported by browsers:
- flif (Cloudinary, comparable results to webp so not likely to get much traction https://cloudinary.com/blog/flif_the_new_lossless_image_format_that_outperforms_png_webp_and_bpg) - jpeg XR (Microsoft, dead like due to politics) - jpeg XL (still under development, promising but very early days) - pik (Google, seems to be more of a side-project strangely) - bpg (like WebP but based off a better video codec) - avif/heif (like WebP but based off a better video codec, promising) There is so much politics and opinion. At the end of the day we only support what browsers can, and are unlikely to do browser-specific transcoding within Composr like Cloudflare or Google Amp might. WebP would provide a decent byte saving. |

It's very promising. The guy who founded MPEG even has a blog post essentially saying MPEG is dead, and "The Alliance For Open Media" has won. Competing open formats such as Xiph.org have also been folded into the efforts.
I hate all the politics (looking at Netflix's blog post you can see even JPEG 2000 is very similar in performance to AVIF - as these competing post-JPEG/MPEG formats are technically similar - it's ego and market domination and patents that is the true story here), but it's very pleasing to see that finally everyone has come together and got behind a royalty free organisation.

WebP is usable as soon as we drop IE11.
AVIF looks like it might be supported, if Safari adopts, and someone has made a patch for that.
JPEG XL seems likely to receive widespread adoption, based on recent discussions. They explicitly reference building on the shoulders of some of the other formats here, and it supports both lossy and lossless encoding. They also are trying to do everything, including supporting animation.
Probably the best strategy is to leapfrom WebP and AVIF, going straight to JPEG XL once that is supported across all our supported browsers. i.e. dump PNG and APNG (and gif) in favour of JPEG XL. A few years from now.

EDIT: We also need to consider PHP supporting JPEG XL too, which may take some time.
