FAQ
Does this run locally?
Yes. Parsing and rendering happen entirely in your browser; content is not uploaded.
What Markdown features are supported?
CommonMark features including headings, lists, emphasis, links, images, blockquotes, and fenced code blocks. Some GitHub-flavored extensions may render depending on input.
Is the output sanitized?
This preview is intended for trusted content. If you paste untrusted Markdown, sanitize the HTML before publishing (e.g., DOMPurify) to prevent XSS.
Can I share a prefilled example?
Yes. Use the Share button—your Markdown is embedded in the URL (?q=...).
Are images proxied or uploaded?
No. Image URLs you include are referenced directly by the browser.
