How Are Images Stored? A Deep Dive into GIF, PNG, and JPEG
(cefboud.com)
This post is me indulging in a rabbit hole. I somehow found myself thinking about images, probably after my recent exploration of some compression schemes. It’s common knowledge that images are either grayscale or RGB, that mixing red, green, and blue creates new colors. But there’s certainly more to storing an image than just aligning three-byte RGB values.

JPEG XL is a new-generation image file format that recently got a big boost to awareness thanks to native support in the iPhone 16 series smartphones. So what is it, why does it matter, and why should you use it? Who better to ask than one of the people who helped make it a reality?

Ask HN: Why aren't more apps using WebP format?
(ycombinator.com)
WebP has been around for a while now, offering better compression and performance over JPEG and PNG. So why haven't more apps fully adopted it yet? Are there hidden compatibility issues, performance downsides, or just inertia in the industry? Curious to hear if the switch to WebP has made a difference for anyone here, especially for mobile performance.

PNG can be Animated Wait WTF? APNG file format
(wikipedia.org)
Animated Portable Network Graphics (APNG) is a file format which extends the Portable Network Graphics (PNG) specification to permit animated images that work similarly to animated GIF files, while supporting 24 or 48-bit images and full alpha transparency not available for GIFs. It also retains backward compatibility with non-animated PNG files.
