Frequently Asked Questions
What is the difference between this and the Markdown Editor?
The Markdown Editor is a live writing tool for working with Markdown. This converter is focused on output — pasting Markdown and exporting a complete, standalone HTML file with optional styling that you can publish directly or send to someone.
What is included in the exported HTML file?
The exported .html file includes the full HTML structure (<!DOCTYPE html>, <head>, <body>), your converted content, and optionally embedded GitHub-style CSS. It is a self-contained file you can open in any browser without additional files.
What Markdown features are supported?
All standard Markdown is supported: headings, bold, italic, code blocks (with language syntax hints), tables, blockquotes, lists, links, images, strikethrough, and horizontal rules. The parser follows the CommonMark specification.
Can I include custom CSS in the export?
Yes — the GitHub CSS toggle embeds a clean, readable stylesheet. For custom styling, you can also paste your own CSS in the settings panel before exporting.
Is my Markdown sent to a server?
No. The entire conversion runs in your browser using a JavaScript Markdown parser. Your content never leaves your device.
