  4. Click "Copy HTML" to copy the output, or "Download .html" to save it as a file.

Frequently asked questions

Does anything get uploaded?
No. The conversion runs entirely in your browser using the marked library — your text never leaves your device.
Which Markdown features are supported?
All CommonMark features: headings, bold, italic, links, images, code blocks, blockquotes, ordered and unordered lists, horizontal rules, and tables (GFM).
Can I use the downloaded HTML file directly?
The download contains the converted HTML fragment. You can paste it into an existing page or wrap it in a full HTML document with a <head> and <body> to use it standalone.
Is there a size limit?
There is no enforced limit — conversion happens locally, so performance depends only on your device.
