Lossless converting the palleted PNG (at 100671 bytes ≈ 101 kB) to JPEG XL result in a file at 25178 bytes ≈ 25 kB.

Converting lossless to webp, using

cwebp -lossless -m 6 -z 9 -o e08463_353cfb9f6bf646159fdf9dc573b1080e.{webp,png}

the file is 85118 bytes ≈ 85 kB. Lossy webp (i.e. without `-lossless`) is 437632 bytes ≈ 438 kB

Managed to get portable Linux AppImage binaries to work, so I'm pushing a new release of HDRView! Same as v2.7.0, but with precompiled binaries for Linux.

Tesing _lossless_ optimizing #Mastodon's media_attachments folder from an export https://docs.joinmastodon.org/user/moving/#export i.e. from https://mastodon.social/@aslakr/media

- Original size of media_attachments: 576M

- After a simple `oxipng --alpha` on all the PNGs: 541M

- Using `oxipng --alpha --strip pHYs,eXIf --zopfli` on PNGs: 539M

- Losslessly convert to JPEG XL using `cjxl -e 10 -d 0` on all JPEGs: 500M

- Lossless convert all PNG to JPEG XL: 453M

Take your information and do what you want with it.

It took three years, but JPEG XL will be coming back to Chromium (using jxl-rs, the Rust implementation).

It is nice to see that a superior, open technology can win in the end.

The WebKit and Safari teams provided a huge boost in 2023, because if they hadn’t shipped it there would have been fewer reasons for CDNs and others to support it too. Cloudinary, a big supporter, is now serving about a billion JPEG XLs per day, presumably almost entirely to users of Safari/WebKit.

Das ist aber schön, JPEG XL erfährt nun doch breite Unterstützung. Vor drei Jahren hatte Google das Format aus Chromium entfernt und wenig später auch das Firefox-Team. Doch jetzt soll das Format im PDF-Standard dafür sorgen, dass PDF auch HDR-Grafiken unterstützt. Und schwupps  wird das demnächst wieder in Chromium eingebaut:

Collin Allen (@command_tab@hachyderm.io):
It looks like because the PDF standard is adopting JPEG XL to support HDR images, the Chromium maintainers changed course and now *are* going to implement JPEG XL in the browser, and they're going to do it by integrating jxl-rs 🎉 #^https://issues.chromium.org/issues/40168998

By the way, the fact that #Google has changed their opinion on #JPEGXL shows that they can be made to do the right thing, by simply ignoring them and doing the right thing yourself. Too bad #Mozilla isn't listening.
🎉 #Google performs its trademark magic trick—*unkilling* JPEG XL, proving that tech #resurrection is the new innovation! 🎩✨ Meanwhile, JPEG XL is still waiting for its call back to the browser party, while #AVIF smugly hogs the spotlight with Google’s not-so-invisible hand. 🙄🔍
