Markdown Preview — FAQ
Got questions? Files, formatting and privacy, in short.
How do I view a .md file online without installing anything?
Click Upload in the toolbar or drag and drop your .md or .markdown file into the editor. The file is read entirely in your browser — nothing is uploaded to a server. The rendered preview opens instantly in the Preview tab.
How do I convert Markdown to formatted, readable text?
Paste or upload your Markdown into the Markdown tab. The Preview tab renders it as formatted HTML in real time. Click Copy Formatted to copy the rich-text output and paste it into Google Docs, Notion, email clients, or any rich-text editor.
What is GitHub Flavored Markdown (GFM)?
GFM is GitHub's extended Markdown specification. It adds tables, task lists (- [ ] item), strikethrough (~~text~~), and fenced code blocks with language specifiers. This tool renders the full GFM spec, matching how GitHub renders READMEs and pull request descriptions.
Does this support syntax highlighting in code blocks?
Yes. Fenced code blocks with a language hint (e.g. ```js, ```python, ```bash) are automatically syntax-highlighted using highlight.js, covering 190+ programming languages.
Is my content processed securely?
Fully. All Markdown rendering happens in your browser using JavaScript. No text, file content, or metadata is ever sent to any server.
Can I preview Markdown from a GitHub README or documentation file?
Yes. Copy the raw Markdown source from any GitHub README, wiki page, or documentation file and paste it into the Markdown tab. The tool renders it with the same GFM rules GitHub uses — tables, task lists, and syntax-highlighted code included.
