It’s High Time to Replace JPEG With a Next-Generation Image Codec
I can be quite passionate about image codecs. A “codec battle†is brewing, and I’m not the only one to have opinions about that. Obviously, as the chair of the JPEG XL ad hoc group in the JPEG Committee, I’m firmly in the camp of the codec I’ve been working on for years.

Modern Image Formats For The Web | DebugBear
Track page speed over time and get the data you need to optimize it. Choosing the right image format is the first and most important step when it comes to image performance. We want our websites to load fast, but we also want our images to look good. Balancing these two concerns is the core of image performance. Image formats are file types for digital graphics that have evolved over time to make

Images have also been a key part of the web. They communicate ideas instantly, but they are also a lot heavier than text to load. This means that it’s essential to get loading and displaying them right, if you want to give your users a fantastic first impression. An excerpt from Addy’s new book (also, check a free PDF preview).

image2cpp
image2cpp is a simple tool to change images into byte arrays (or arrays back into an images) for use with (monochrome) displays such as OLEDs on your Arduino or Raspberry Pi. It was originally made to work with the Adafruit OLED library (for which your can find an example sketch for Arduino here) but has been expanded by the community to be useful in all kind of (embedded) projects.

Maximally optimizing image loading for the web
In this post I'll outline 8 image loading optimization techniques to minimize both the bandwidth used for loading images on the web and the CPU usage for image display. I'll present them in the form of an annotated HTML example to make it easy for folks to reproduce the results. Some of these techniques are more established, while others are somewhat novel. Ideally, your favorite mechanism for pub

AVIF has landed
Back in ancient July I released a video that dug into how lossy and lossless image compression works and how to apply that knowledge to compress a set of different images for the web. Well, that's already out of date because AVIF has arrived. Brilliant. AVIF is a new image format derived from the keyframes of AV1 video. It's a royalty-free format, and it's already supported in Chrome 85 on desktop
