ToolFox

Markdown Previewer

Live side-by-side Markdown editor and preview — headings, lists, links, code and tables.

Hello ToolFox

Type markdown on the left, see the preview on the right.

How it works

The left pane is plain Markdown; as you type it is converted to HTML with a CommonMark-compatible parser and sanitized so that scripts, event handlers and other dangerous HTML can never execute — then rendered in the right pane exactly as a README or blog engine would show it.

Example

Type # Release Notes, a bullet list and a [link](https://example.com) — the preview shows the rendered heading, list and clickable link instantly. Paste a GitHub README to proof it before committing.

Frequently asked questions

Which Markdown flavour is supported?

CommonMark plus common extensions like tables and fenced code blocks — close to GitHub-Flavored Markdown for everyday documents.

Can I get the HTML out?

Yes — the preview is real HTML; copy it from the page, or use your site generator for production conversion.

Is embedded HTML allowed?

Safe tags pass through; scripts, iframes and event handlers are stripped by the sanitizer.

Is my text uploaded?

No — conversion happens locally as you type.
