Open a Markdown file and read it the way it is meant to look, with headings, lists, tables and code blocks rendered properly. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.
How to do it
- Drop in a
.mdfile, or paste Markdown into the box. - Read the rendered version.
- Switch back to the source at any time to see what produced it.
Questions
Which flavour of Markdown does it understand?
CommonMark, plus the GitHub extensions people actually use: tables, task lists, strikethrough and fenced code blocks with a language tag.
Is HTML inside the Markdown rendered?
It is sanitised first. Markdown allows raw HTML, and a document from somewhere else could carry a script; anything of that kind is removed before the result is shown. What you see is the document’s content, not its ability to run code.
Can I open a large file?
Yes. Rendering happens in your browser, so the limit is your device’s memory rather than an upload cap. Very long documents take a moment to lay out.
Is the file uploaded to render it?
No. Nothing leaves the page.
