About Markdown Preview Editor
This is a live Markdown editor and previewer. You type Markdown on the left and the rendered result appears instantly on the right, along with word, character, line, and reading-time counts. When you are happy with it, you can copy the generated HTML, copy the Markdown back out, or download either as a .html or .md file.
It supports the common Markdown you actually use: ATX headings, bold, italic, strikethrough, inline code and fenced code blocks (with an optional language label), links, images, blockquotes, ordered and unordered lists, GitHub-style task lists, tables with column alignment, and horizontal rules. The parser is built into the page, so there is no library download or API call.
Everything runs privately in your browser — your text is never uploaded or stored on a server. For safety the preview escapes any raw HTML you paste and blocks unsafe link schemes like javascript:, so what you see is a faithful, sandboxed render rather than a full CommonMark or GitHub-flavored implementation. Deeply nested lists and some rarer edge cases are simplified.
Frequently asked questions
- How do I use the Markdown preview editor?
- Type or paste Markdown into the box on the left. The formatted preview updates instantly on the right as you type. Use the buttons to copy the HTML, copy the Markdown, or download either file.
- Which Markdown syntax is supported?
- Headings (# to ######), bold, italic, and strikethrough, inline code and fenced code blocks, links and images, blockquotes, ordered and unordered lists, task lists with checkboxes, tables with alignment, and horizontal rules.
- Is my text private?
- Yes. The tool runs entirely in your browser using JavaScript. Nothing you type is uploaded, logged, or saved on a server, and there is no sign-up.
- Can I get the HTML out to use elsewhere?
- Yes. Click Copy HTML to put the rendered HTML on your clipboard, or Download .html to save a file. You can also copy or download the original Markdown.
- Is this a full CommonMark or GitHub-flavored Markdown renderer?
- It covers the most common syntax but is intentionally lightweight. To keep the preview safe it escapes raw HTML and blocks unsafe link schemes, and it simplifies some rarer cases like deeply nested lists, so it is not a 100% CommonMark-compliant parser.
- Why is my raw HTML showing as text instead of rendering?
- The preview deliberately escapes any embedded HTML so pasted content cannot run scripts or break the page. Use Markdown syntax for formatting; literal HTML tags are shown as plain text.
