The truth is, #WebP is only a stopgap. The real deal is #AVIF and ultimately #JPEGXL (.jxl).
JPEG-XL is superior in almost everything. In the very few cases that it is not, that's where AVIF comes in.
We can get rid of WebP, old JPEG, GIF, later on. Maybe even PNG and APNG.

Tonight I managed to create a gainmap-style (SDR+HDR) #avif using the latest git version of libavif, converting from an UltraJPG (jpg with gainmap) using avifgainmaputil. Conclusion: No browser support! At least high bitdepth #avif is supported by all browsers except #firefox.
See blog.yuo.be/2025/05/08/p... for similar experimental results with Firefox.
I still think #AVIF is the way to go for web-friendly HDR images! FF will eventually catch up.
... It seems that #bluesky converted the attached avif to jpeg, so you won't be able to see the difference.
Source AVIF (converted with #graphicconverter 12) is at: cpbotha.net/2026/02/07/t...

All the #Chrome family browsers as well as #Safari render the attached #HDR #AVIF image correctly on my 16" M1 MacBook display. #Firefox 147 over-saturates / washes out the colours, also 16bit #PNG ver. gfx.color_management.mode=1 & restarting does not help. Source #blog cpbotha.net/2026/02/07/t...

New Halide blog post on post-processing for chroma as it is relevant to compression efficiency: halide.cx/blog/chroma-...
Seems like you can get a roughly 2% efficiency improvement with 4:2:0 decoder output just with smarter post-processing for chroma. Pretty neat!

SVT-AV1 4.0.0 is here!
Changelog: gitlab.com/AOMediaCodec...
SVT-AV1-PSY's porting efforts are fully complete, and this release also features huge AVIF improvements. Maybe the most exciting release to date by my standards – SVT-AV1 is finally a real perceptual encoder!
#av1 #avif #compression
New AVIF 1.2 standard with sample transforms for higher bitdepths + guidance on gainmaps for backwards compatible HDR: aomedia.org/blog%20posts...
(I have started experimenting with #AVIF on my personal #blog: cpbotha.net/2025/12/25/w... )
P.S. maybe I'm back on @bsky.app after 2 month break.

Sym8 version 2.84.1 is out now.
This release delivers a smoother installation, secure backend-only updates, accessibility improvements and added #BMP & #AVIF image support.
#Sym8 #SymphonyCMS #OpenSource
The JIT Image Manipulation extension has been improved!
It now supports two additional image formats: BMP and #AVIF.
Compatibility has been enhanced by adding conditional imagedestroy() and unset() logic for #PHP7 and #PHP8 environments.

Hell effin yeah! #jpegXL will most likely be back in #google #chrome! Hopefully we will be (soon-ish) free of darn #webp and #avif!

AVIF 이미지 테스트. 혹시 사진 안 보이시는 분이 있으시면 멘션 주시면 감사하겠습니다. 😊

A screenshot of "Deer Fork" showing its Images format feature for Thumbnail and Fullsize, in the example it is AVIF and WebP respectively.
In #DeerFork (a fork of deer.social) there is a cool feature related where the user can choose thumbnail and fullsize image format.
From my tests, thumbnails as #AVIF produces smaller filesize while for fullsize it is better as #WebP (smaller filesize).

avif webp jpeg 용량 비교
포맷별 용량의 차이 비교는 이 블로그에 잘 정리되어있다.

이미지 포맷별 용량
이미지 해상도나 내용의 복잡도에 따라 다르겠지만 이미지 크기는 png > jpg >>>> webp >> avif 순으로 작아진다.
png가 수 MB 라면, webp는 수백 KB, avif는 수십 KB로 비교할 수 없게 작아지지만 품질의 차이는 거의 없다.

즉, 블로그의 대표이미지는 보편적인 이미지 형식으로 해야한다.
쓰레드, bluesky 등의 SNS야! avif 지원해주면 안되겠니?

차세대 이미지 호환성
워드프레스 블로그에 avif를 쓰면 속도도 빠르고 좋은데 이를 SNS(ex: 쓰레드, X, Bluesky) 에 올리면 avif 형식의 대표이미지를 보여주지 못한다.
너무 아쉽다.
