What this MD file viewer supports

An md file viewer renders Markdown — the format of README files, release notes, and AI-generated documents — as formatted text instead of raw syntax. Every feature below runs entirely in your browser:

GitHub-Flavored Markdown: tables, task lists, strikethrough, footnotes-style links
Syntax-highlighted code blocks
Math formulas via LaTeX/KaTeX (inline $...$ and block $$...$$)
Mermaid diagrams: flowcharts, sequence diagrams, class diagrams
Automatic table of contents from your headings
Export to PDF, standalone HTML, or PNG image

How to use

Open a local file — drag it onto the box above, or click to browse. Works offline once the page is loaded.
Paste Markdown — copy any Markdown source and paste it into the text box above (or anywhere on this page).

Privacy: your files never leave this device

This page is static. Parsing and rendering happen in your browser with JavaScript — there is no server to receive your file, no account, and no tracking of document contents. You can verify this yourself: open your browser's network tab, drop in a file, and watch that nothing is transmitted.

FAQ

Is this markdown viewer free?

Yes — free, no sign-up, no limits.

What's the file size limit?

Whatever your browser can handle — there is no server-side cap because nothing is uploaded. Documents of several megabytes render fine on modern devices.

How is this different from a markdown editor?

A viewer is for reading: open the file, see the rendered result, export or copy it. There is nothing to install and no account to create — unlike desktop editors.

Does it work on mobile?

Yes. On a phone you can pick a .md file from your Files app via the browse button, or paste Markdown directly.

Which file extensions are accepted?

.md, .markdown and .txt — the same files a markdown preview or md reader tool would open.
