Technical-Writing

For precise technical diagrams, prompt an LLM to output SVG or Mermaid.js syntax instead of pixel-based images. This creates lightweight, resolution-independent graphics that search engines can read. Vector formats offer performance and clarity that raster images simply can’t match.

Why SVG? The Case Against Raster Images for Technical Diagrams

Most bloggers use screenshots or PNG exports for diagrams. This habit seems easy but carries hidden costs. A PNG flowchart often weighs 100 KB to 400 KB. In contrast, the same SVG diagram usually stays between 5 KB and 20 KB. This huge difference improves Core Web Vitals metrics like Largest Contentful Paint. Better performance helps your search rankings.
