Simple by design
Markdown to HTML in three steps
FileGizmo converts CommonMark Markdown into HTML entirely in your browser. Paste headings, lists, links, quotes, emphasis, and fenced code, then choose an HTML fragment or a standalone document. The standalone option adds a UTF-8 declaration, responsive viewport metadata, a title, and restrained readable styles without external assets.
Safety is intentional. Embedded raw HTML is not enabled, and dangerous URL protocols are blocked by the Markdown parser defaults. This prevents pasted <script> elements or javascript: links from becoming active output. The preview is isolated in a sandboxed frame and the source HTML remains available as text for inspection. These defaults prioritize safe notes and documentation over raw-HTML passthrough.
Conversion runs in a worker and produces an HTML blob with the correct filename and MIME type. Copy the generated markup or download it for a static page, documentation system, or further editing. Review links and complex Markdown extensions before publishing: the converter targets portable CommonMark rather than every platform-specific extension, plugin, or custom component syntax.
