Markdown is parsed locally and raw HTML is shown as text.
How to preview Markdown
Write Markdown and see a formatted preview for README files, documentation, notes, and drafts.
Supported Markdown
The preview supports common writing syntax: headings, paragraphs, ordered and unordered lists, blockquotes, code blocks, inline code, emphasis, strong text, and HTTP or HTTPS links.
Safe preview behavior
Raw HTML is displayed as text instead of being executed or inserted into the page. Links are only rendered when they use http or https.
How to use it
- Type or paste Markdown into the editor.
- Review the live preview on the right.
- Adjust headings, lists, and code until the document reads clearly.
Local preview
Markdown is parsed in your browser and is not uploaded to ProntoUso.
