Bon c'est quand même compliqué cette envie de compresser mes photos en avif parce que c'est pas bien géré. Les applications Flutter affichent une version grossièrement décompressée pleine d'artefact, Signal capte juste pas de quoi il s'agit et dans les applications où l'image s'affiche ça ne tient pas compte de l'orientation EXIF (et dans un cas où j'ai recadré une photo elle s'est affichée toute étirée avec le ratio d'origine…)

J'ai essayé webp mais ça fait un vieux lissage moche qui bouffe détails et grain de photo…

Hold on a minute, vous me dites que je peux convertir les JPEG qui sortent de mon appareil photo en AVIF et diviser leur poids par 10 ?

SVT-AV1 4.0.0 is here!
Changelog: https://gitlab.com/AOMediaCodec/SVT-AV1/-/releases/v4.0.0
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!

Extracting embedded images from a PDF

Surprisingly, the best way (that I’ve found) to do this is to use The Unarchiver, a free app from MacPaw (the folks behind SetApp and many other things). It seems to faithfully extract the images as-is, including ICC profiles (which might technically be separate from the image within the PDF, but nonetheless are crucial to the image being extracted correctly).

The primary reason to extract […]

🌖 Google 讓 JPEG XL「復活」：經歷波折後，該圖像格式即將成為主流
➤ 從被摒棄到重獲新生：JPEG XL 的逆襲之路
✤ https://tonisagrista.com/blog/2025/google-unkills-jpegxl/
本文回顧了 JPEG XL 圖像格式從被 Google Chromium 團隊放棄到重新獲得支援的曲折歷程。儘管曾因生態系統支持不足而被 Chromium 移除，但隨著 Safari、Firefox 瀏覽器以及 PDF Association 等組織的積極響應，Chromium 團隊最終迴心轉意，撤銷了對 JPEG XL 的棄用標籤。作者認為，JPEG XL 憑藉其無損重新壓縮 JPEG 的能力、對寬色域和 HDR 的支援、超大圖像尺寸限制以及流暢的網頁載入特性，極具潛力成為未來的圖像標準。
+ 太好了！JPEG XL 的功能確實遠超現有格式，尤其是在無損壓縮和 HDR 方面。希望這次 Chromium 的決定能帶來真正改變。
+ 雖然高興 JPEG

Naev 0.13.0-beta.2 is out!

A few issues have been fixed, but by far the most notable change in this (pre-)release is the swap to lossy assets. Naev will now use lossy AVIF and less bloated Vorbis files internally (with support for Opus audio on the way)

Already the game's download sizes have been slashed by 60-70%!!
