How the crawl works
The crawler starts at the page you give it, follows the site's internal links breadth-first, runs the same readability + Markdown conversion as our single-page tool on each page it reaches, and stops at the number of pages you asked for. The crawl runs in the background while the page shows its progress; when it finishes, download everything as a single Markdown file or as a ZIP with one file per page.
Single page or whole site?
If you have one URL in hand, use Webpage to Markdown — simpler workflow. Use Website to Markdown when you want to crawl across many pages: a docs site, a blog archive, a help center, a public knowledge base. Both produce identical per-page Markdown output; this tool just orchestrates the crawl, the deduplication, and the packaging.
Crawl politeness
Crawls stay on the site you started from. Run them on your own properties, or on sites whose terms allow it. Don't use this to scrape sites whose terms of service forbid it; we don't bypass anything technical, but the social contract still applies.
