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.
