UserAgent: Mozilla/5.0 (iPhone; CPU iPhone OS 9_0_2 like Mac OS X) AppleWebKit/601.1.46 (KHTML, like Gecko) Version/9.0 Mobile/13A452 Safari/601.1 Steps to reproduce the problem: Chromium does not support the new FLIF-Format yet. What is the expected behavior? Support for FLIF would be nice! What went wrong? Does not apply. Did this work before? No Chrome version: Latest Channel: stable OS Version: All Flash Version: FLIF is a new Image-Format which works lossless. Else it supports very good preview of partial-downloaded images, so it is possible to limit the downloads of images to a percentage-size on mobiles, to use lossy compressions where necessary. Else FLIF has better compression ratios than PNG/JPG2000 lossless/WebP-Lessless and all other lossless-formats. It looks better than JPG progressive on same partial download-size and does have relatively good compression/decompression times. All informations can be found here: http://flif.info

To show the differences between JPG and FLIF. I loaded a PNG (4752x2418 pixel) of 6,6 MByte in FLIF, which resultes in 3,8 MByte (transcode-time: 1m43s on a i3 2nd gen). Now I cutted the first 73 KByte of the file, and decoded them. This results in the following image: https://imgur.com/vkfgL5Q Now I transcoded the original image to JPG and slided on the quality as long as 73 KByte is achieved. Here is the JPG: https://imgur.com/nMqLXLA The original image can be found here: https://imgur.com/afg0n51 Conclusion is, that on this very large image 2% of download is enouth for a SVGA-Preview.

Confirming the above issue as Feature-Request and marking it as untriaged.

The bar to get a new image format into Chromium is incredibly high. (For example, note that we still don't support APNG despite Firefox supporting it for years.) While we're not ruling out ever supporting this format, it's not really appropriate for consideration yet. The format's own homepage notes numerous major TODOs that would need to be addressed to consider this. Once FLIF is a stable format and has either implemented or intentionally WONTFIXed all TODOs, it might be possible to reconsider it. However, rather than raising this directly in Chrome's bug tracker, this should be brought up as a general discussion across all browser vendors, since if possible the vendors should try to reach agreement on whether this is compelling. At that point it would be very helpful to have evidence of strong web author desire for this. Good compression ratios are important, but so are numerous other factors.

Which TODOs would you need to see implemented or crossed off? I think supporting the format in Chrome would help drive adoption. The image format has the potential to greatly reduce page load times and reduce total bandwidth used on image heavy sites (ie, pretty much every site).
hope this get implemented soon. great image format!
"The bar to get a new image format into Chromium is incredibly high."... I really do like FLIF, but FLIF'S author is competing with Google as the main promoter of WebP - which is is fast, has ok lossy and good lossless compression. Even if it's better than XR or 2K, FLIF might need have very good reasons to merit its inclusion. Alas, some of its strengths like no generation loss and high bit depths aren't critical for Internet usage. Plus atm(!) it's slow and compression isn't that revolutionary for general photographic images vs. pre-processed near-lossless webp. That leaves us with FLIF in a browser as a PNG-ish replacement for other image types than photography ... certainly nice to have, but I'm personally using it as a offline format for image editing and adoption for gimp and ps seems more critical to me. Ymmv.
