How to use markdown live preview
Start writing in the Markdown editor or open an existing .md file from your device.
Review headings, lists, links, emphasis, code blocks, and safe data images in the live preview.
Copy the Markdown source or download it as a .md file when your document is ready.
Clear the page or close the tab; the source remains local and is never uploaded.
What this tool does
- Split editor and live preview that updates as you type
- Headings, paragraphs, lists, blockquotes, code fences, emphasis, links, and inline code
- Safe data-URI images while remote images and raw HTML remain blocked
- Open, copy, and download Markdown files locally
- No account, server upload, or external Markdown runtime
How the result is verified
The preview is built from React elements rather than injected HTML. Link protocols are allow-listed, remote images are blocked, and the downloaded output is the exact Markdown source currently shown in the editor.
Frequently asked questions
Is this Markdown editor free?
Yes. The editor and preview run locally in your browser with no account or upload requirement.
Can I open and download an existing Markdown file?
Yes. Open an .md, .markdown, or .txt file, edit it in the left panel, then download the current source as a Markdown file.
Does it render raw HTML or remote images?
No. Raw HTML, scripts, remote images, and executable content are blocked to keep the preview safe. Data-URI images can be displayed.
Is my file uploaded to a server?
No. The file is opened with your browser's File API and processed by code running in your tab. You can confirm this yourself: open your browser's developer tools, watch the Network panel, and process a file — no request carries your file's bytes. See our How it works page for a step-by-step verification guide.
