FAQ

Q: Is the conversion faithful to GitHub-Flavored Markdown? A: It uses the marked parser with sensible defaults (tables, strikethrough and task lists are handled). Edge-case extensions from one specific site may differ — test before large migrations.

Q: Does HTML → Markdown keep tables? A: The Turndown library converts common HTML (headings, lists, code, links, images) to Markdown. Highly custom HTML with inline styles converts less cleanly.

Q: Where does the conversion happen? A: Locally, on demand. Marked and Turndown are small libraries fetched only when you click convert, keeping the page fast.
