Covers why data reduction matters globally, the current state of browser support (none yet, but emulatable), and concrete implementation strategies: conditionally loading web fonts, serving smaller or no background images, using the `` element for responsive images, preventing video autoplay/preload, and replacing infinite scroll with a load-more button. Also covers the existing `Save-Data` header and the Network Information API as current alternatives, plus how to test using Polypane or Chromium flags. ## Full article daily.dev links to this article rather than hosting it.
