Frequently asked questions
Do these Markdown tools upload my content?
No. All Markdown processing happens locally in your browser. The single documented exception is the Link Checker, which fetches the URLs you ask it to check.
What's the difference between the editor and the HTML converter?
The editor is a live, editor-first workspace for writing Markdown. The converter is a paste-in, convert-and-done tool for HTML source.
Does the anchor generator match GitHub exactly?
Yes — it uses GitHub's slugification algorithm, including -1/-2 suffixes for duplicate headings, so anchors always match what GitHub renders.
