Why Use Our Markdown Converter

How It Works

Frequently Asked Questions

What markdown flavors are supported? +

The converter supports common Markdown including headings, emphasis, links, images, blockquotes, fenced code, ordered and unordered lists, and basic tables. Specialised extensions such as footnotes and mathematical notation are not supported.

Can I process multiple files at once? +

Yes. You can select multiple .md, .markdown or .txt files, convert them locally, and download each converted HTML file. Folder structures are not preserved.

Are my files stored on your servers? +

The conversion and file handling run in your browser. The tool does not intentionally upload your entered content or selected files to ToolCookie servers. The page may still load normal website resources, such as fonts, according to the site privacy policy.

What export formats are available? +

Download Markdown-to-HTML results as a styled HTML file or HTML-to-Markdown results as a Markdown file. You can also copy the converted source directly to your clipboard.
