Google snubbed JPEG XL so in fact Apple now helps it in Safari

Apple is now supporting JPEG XL – a novel royalty-free picture codec that Google final 12 months controversially deserted – in its Safari browser.

The Safari 17 Beta Launch Notes reveal that help for JPEG XL has been added, bringing with it numerous purported benefits over different picture compression and decompression applied sciences.

Apple’s endorsement has renewed requires Google to revisit its elimination of JPEG XL help within the open supply Chromium venture – a choice that denied the codec to Chrome and to different downstream browsers like Microsoft Edge.

“Now that Apple goes to implement JPEG XL in Safari, I ask for this choice to be reversed as quickly as attainable,” wrote one particular person amongst a number of who’ve posted to the JPEG XL Chromium problem thread because the Apple announcement.

Googlers are amongst those that beforehand extolled the virtues of JPEG XL. In 2021, Jyrki Alakuijala, technical lead at Google Analysis, prompt that help for the codec be added to Chromium’s Blink rendering engine.

Alakuijala’s proposal cited numerous causes to undertake JPEG XL – together with higher picture high quality for a given file measurement than JPEG, higher loading habits, and “ecosystem curiosity in JPEG XL” at Google, Fb, and different corporations.

But when Google reversed course, one of many causes cited was: “There may be not sufficient curiosity from the complete ecosystem to proceed experimenting with JPEG XL.”

There may be not! There may be, too!

Whereas Mozilla has managed to declare its neutrality with regard to JPEG XL, there’s ample proof of ecosystem curiosity.

Jon Sneyers, senior picture researcher at Cloudinary and editor of the JPEG XL spec, pushed again towards Google’s declare in an online essay final November.

“If the enthusiastic help within the Chromium bugtracker from Fb, Adobe, Intel and VESA, Krita, The Guardian, libvips, Cloudinary, and Shopify is any indication, it appears baffling to conclude that there can be inadequate ecosystem curiosity,” he wrote.

Greg Farough, campaigns supervisor for the Free Software program Basis, additionally challenged that assertion in a weblog publish final month.

“Chromium customers got here out of the woodwork to plead with Google to not make this choice,” mentioned Farough. “It made it anyway, not bothering to answer customers’ issues. We’re undecided what metric it is utilizing to gauge the curiosity of the ‘complete ecosystem,’ but it surely appears customers have given JPEG XL a robust present of help. In flip, what customers might be given is one more side of the online that Google itself controls: the AVIF format.”

AVIF is patent-encumbered. It is managed by The Alliance for Open Media – an business consortium that counts Google as a member.

That is (arguably) not the case for JPEG XL. “In contrast to another trendy codecs, JPEG XL shouldn’t be encumbered by patents nor does it require proprietary software program,” the codec’s documentation web site explains. “The reference software program, libjxl, has a permissive open supply license and is a production-ready library that may be (and already has been) built-in into quite a lot of image-related software program.”

Redmond looms

A patent granted to Microsoft final 12 months overlaying a data-encoding approach known as rANS (vary Uneven Quantity System) may complicate the image.

Sneyers advised The Register he does not imagine the Microsoft patent is related.

However others, resembling Jarosław Duda, assistant professor at Institute of Laptop Science at Jagiellonian College in Poland and developer of ANS (from which rANS is derived), have expressed concern as a result of JPEG XL makes use of rANS to enhance picture compression.

When The Register corresponded with Duda final October, he mentioned Google’s choice to drop help for JPEG XL was pushed by engineers who favored AVIF know-how, and represents unfair competitors that must be addressed by regulators.

“These selections by Google engineers, who’ve a vested curiosity within the competing requirements of AVIF and WebP succeeding, stifle their JPEG XL competitors by eradicating help for the JPEG XL codec after which promote a Google know-how monopoly by mendacity in regards to the neighborhood curiosity in JPEG XL and the incremental advantages that JPEG XL presents,” he mentioned. “That is antitrust.”

Duda argued that Google’s dismissal of JPEG XL exhibits that the tech big ought to be compelled to show over management of the open supply Chromium venture to impartial governance.

For its half, Google seems to be hedging its bets: a separate entry within the Chromium bug tracker requires continued testing of JPEG XL libraries to make sure JPEG XL help might be revived in Chrome at any time. ®
