Frequently asked questions
- What Markdown syntax is supported?
- Headings (# through ######), paragraphs, bold (**text** or __text__), italic (*text* or _text_), bold-italic (***text***), strikethrough (~~text~~), inline code (`code`), fenced code blocks (```), links ([label](url)), images (), unordered lists (-, *, or +), ordered lists (1. 2. 3.), blockquotes (>), and horizontal rules (--- or ***).
- Is my text sent to a server?
- No. The conversion runs entirely in your browser using JavaScript. Your Markdown is never uploaded, stored, or shared with anyone.
- Can I use the output HTML directly on a webpage?
- Yes. The generated HTML uses standard tags (<p>, <h1>–<h6>, <ul>, <ol>, <pre>, <code>, etc.) and is safe to paste into any HTML document or CMS editor.
- Are JavaScript and CSS injected into the output?
- No. The converter only outputs content-level HTML tags. It does not add any <script>, <style>, or <link> elements. HTML tags in the Markdown input are escaped, so raw HTML in your Markdown will appear as literal text.
- What happens to raw HTML in Markdown?
- HTML tags typed in the Markdown input are escaped — <br> becomes <br> in the output. This prevents accidental XSS and makes the output safe to embed in any context.
