Bitrot resistance of next-generation image formats

2021-11-26T12:09:00Z

I’ve compared two next-generation image formats, AVIF and JPEG XL (JXL), to see which best handles a random single corrupted bit. A meaningless exercise? Possibly. But half a picture of your beloved grandma is better than no picture at all.

The best method for embedding dark-mode friendly SVG in HTML

2021-06-11T12:06:00Z

In this article, you’ll learn about the different methods for embedding Scalable Vector Graphic (SVG) images onto webpages. I’ll discuss which methods support the various security and processing modes in SVG, which methods support dark mode using @media queries, and which are the most caching friendly. I’ll also touch on why the most backward-compatible embedding method is the worst for perceived performance and has the most accessibility bugs.

Comparing file sizes of lossless WebP vs FLIF vs PNG

2020-07-14T02:26:00Z

Last weekend, I compared two lossy image formats: AVIF and WebP. Today, I’m comparing the file size reduction of two lossless formats — FLIF and lossless WebP — compared to heavily optimized PNG images.

Comparing AVIF vs WebP file sizes at the same DSSIM

I wanted to improve the image quality on the blog while keeping the file sizes small. To this end, I wanted to improve the visual quality of my WebP images and explore the new AVIF image format. Here are my findings from comparing WebP and AVIF to JPEGs at the same visual quality.

Enable the sharp YUV option for better WebP images

Did you know there’s a setting for the reference WebP image encoding library (libwebp) that noticeably improves image quality without increasing the file size? It’s safe for batch conversions and its only downside is that it consumes additional processor time during encoding.
