Frequently asked questions
Is my text saved?
Yes. The editor autosaves to this browser's local storage, so your draft is still here when you come back. Clearing site data removes it.
Which Markdown flavor is supported?
GitHub Flavored Markdown: tables, task lists, strikethrough, fenced code blocks and autolinks.
Is my text uploaded?
No. Editing, preview and export all happen in your browser. The preview is sanitized, so scripts in pasted HTML do not run.
Are my files uploaded anywhere?
No. Markdown Editor runs entirely in your browser. Your files are processed on your device and are never sent to a server.
Is there a file size limit?
No fixed limit. The only limit is your device's memory. Very large files work best in a desktop browser.
Is Markdown Editor really free?
Yes. There's no account and no watermark. A short optional ad, or a 20-second wait, unlocks each download. That's how we keep it free.
