Frequently asked questions
What can I extract from a markdown file?
The tool extracts the full heading outline, all links (external, internal, and anchor), images with their alt text, code block languages, and YAML frontmatter fields.
What is YAML frontmatter in markdown?
Frontmatter is a block of YAML at the very top of a markdown file, delimited by ---. It is used by tools like Hugo, Jekyll, Astro, and Obsidian to store metadata such as title, date, and tags.
Can I extract all links from a markdown document?
Yes. The extractor lists every link in the document — external URLs, relative paths, and anchor links — along with the link text for each.
Does the tool upload my markdown file?
No. All extraction runs locally in your browser. Your file is never sent to a server.
Use alongside the Linter to catch quality issues, or the Diff tool to compare document structure across versions.
