A converter that follows nested pages
Most “Notion to markdown online” tools take one public URL and give you one file. That is fine for a single note. It is a bad fit for a published wiki, a course, or a handbook — the pages inside never show up in the download.
This converter reads the public page you pasted, then follows nested pages, sub-pages, and database rows on the same Notion site. Each page becomes its own markdown file. You download a zip. There is no Notion login and no API token.
Official Notion export still needs you to be signed in as a member of the workspace. That cannot save someone else’s published site. If the link opens without asking you to log in, this page can turn it into markdown.
Free keeps image URLs from Notion, which expire. Plus downloads those images into the zip. The free run is capped at 100 pages so you can try the conversion before paying.
