Que fait Markdown Preview ?
Markdown Preview permet de formater et valider des données dans le navigateur et présente clairement le résultat et ses limites. Fonctions vérifiées : Live Markdown rendering, Raw HTML disabled, Link detection, Code fences.
Safe preview does not mean every link is trusted
Disabling raw HTML prevents embedded tags and scripts from executing in this preview. Still inspect destinations before opening links, and sanitize generated HTML again if it will be published elsewhere.
Comment l’utiliser ?
- Enter CommonMark-style Markdown in Markdown source or load the sample.
- Inspect the Safe preview as headings, lists, links, emphasis, and code fences render immediately.
- Copy the preview’s visible plain text when needed; this page does not export or execute raw HTML.
