How it's rendered
marked. Renders Markdown to HTML locally, then displays it inside a sandboxed frame (the same safety treatment as any other untrusted HTML on this site).
Nothing about this file is ever sent to a server — open your browser's DevTools Network tab while using this viewer and you'll see no request carrying your file's contents.
100% Private
Files never leave your device. There is no server that ever receives your file's contents.
No Uploads
Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.
No Storage
Nothing is written to a server or database. Memory clears the moment you close or reload the tab.
GDPR-friendly by design
There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.
Markdown viewer — FAQ
Does it support GitHub-flavored Markdown?
Yes, including tables, fenced code blocks, and task lists.
Can I see the raw Markdown source?
Yes, switch to the Source view for syntax-highlighted raw text.
Is my file uploaded anywhere?
No, it's parsed and rendered entirely client-side.
Does embedded HTML in the Markdown render?
Yes, but it renders inside a sandboxed frame for safety, the same way this site handles any other untrusted HTML content.
Can I edit the Markdown here?
This is a viewer, not an editor. For editing, use your usual Markdown editor.
