Readers download less when they open your blog
Your blog now needs fewer files and less code before it can show the first screen, and images and GIFs are delivered at a size and format that fit the page.
When readers open a post or a list page on your blog, they now download fewer files and less code before the first screen appears. These changes remove things that delayed the first screen on slower connections, such as mobile networks, and apply to every blog without any setup.
- Fewer style files up front: On a blog home that uses the default fonts, the style files needed before the page appears went from four to one. Math styles load only on posts that contain math.
- Styles that aren't downloaded again: Once a reader has your blog's styles, their browser keeps them, so moving to another post on the same blog doesn't request them again.
- Features and images load when needed: The subscribe window and the lead form at the end of a post load when a reader clicks or scrolls to them. On list pages, the first visible card image loads first, and desktop card images are sized to how large they actually appear.
- Lighter GIFs: Animated GIFs in posts are delivered as smaller WebP files when possible, keeping the animation and looping. If a GIF can't be converted or the result would be larger, the original GIF is shown.
Your blog's design and any scripts you added stay the same. GIFs that readers have already loaded switch to WebP when the stored copy is refreshed.
