- 3Hacker News·8/12/2026researchWhy Tiny JPEGs Render Differently in Chrome
The article explains that Chrome can use a JPEG decoding optimization when images are displayed at very small sizes, which can make tiny images look slightly different from Firefox. Rather than fully decompressing and then downscaling the whole image, Chrome can skip some high-frequency data and render an image that better matches the final size.
- 4Hacker News·7/18/2026researchUsing Progressive JPEG Scans to Create Image Switching Effects
The article explores how progressive JPEG encoding can be arranged so that later scans overwrite earlier rendered image data, creating an effect similar to switching between images during slow loading. It also shows the practical limits of decoder scan counts and how a minimal DC-only progressive JPEG can be used to fit more frames before browsers stop decoding.
