web-to-markdown

Clean, dense, LLM-ready Markdown — from any page or raw HTML.

web-to-markdown strips navigation, ads, cookie banners and scripts, and turns what's left into Markdown sized for an LLM's context window. It runs as a CLI, a TypeScript/JS library, or an authenticated API on Cloudflare Workers — same conversion core behind all three.

Handles static HTML and framework-hydrated pages (Next.js, Nuxt, JSON-LD) without a headless browser — when a client-rendered page arrives empty, it reads the data the framework already serialized into the response. It never executes JavaScript, so for pages whose content only exists after their own code runs, with nothing embedded to fall back on, this isn't the right tool.
