Frequently Asked Questions
- Which Markdown syntax is supported?
- Standard CommonMark plus common GitHub-Flavored extensions: headings, bold/italic, links, images, ordered and unordered lists, code blocks and inline code, blockquotes, tables, and horizontal rules.
- Does HTML → Markdown preserve everything perfectly?
- Structural HTML (headings, lists, links, code blocks) converts cleanly. Complex nested layouts, inline CSS styling, and non-semantic divs don't have a clean Markdown equivalent and get simplified or dropped — Markdown is a plain-text format, not a full HTML replacement.
- Is this the same renderer GitHub or GitLab use?
- Not identical, but built on the same CommonMark-compatible parsing rules most Markdown tools share. GitHub Flavored Markdown adds a few extras (task list checkboxes, some autolinking behavior) that may render slightly differently here.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
