About this tool

Markdown Viewer is a static, client-side tool with no backend. Markdown Viewer renders Markdown to HTML in your browser, sanitising the output so pasted content is safe to preview.

The renderer strips dangerous markup so a preview cannot run injected scripts. It behaves the same on desktop and mobile, with nothing stored remotely.
