Notes:1. Rendering happens locally in your browser and covers the common Markdown syntax — headings, paragraphs, lists, tables, links, blockquotes, code blocks and so on.
2. This is a read-only reader; it offers no editing or export. To convert to Word / PDF, use
Markdown to Word / PDF.
3. If the Markdown references local images, the browser cannot read image files sitting in the same folder — link to images by URL instead.
About .md files and how to open them
What kind of format is .md, exactly?
.md is the extension for Markdown files, sometimes spelled .markdown. It is not a binary format — underneath it is an ordinary plain-text file that follows a very light set of formatting conventions: a hash marks a heading, asterisks mark bold text or list items, backticks mark code. Because it is plain text, a .md file is tiny, Git can diff it line by line, and it never hits the "won't open" or "wrong version" problems that .doc files do. GitHub project READMEs, most technical documentation, and notes from Obsidian or Typora are almost all stored as .md.
Why is it full of # and * when I open it?
Because the file is being shown as raw text, with no rendering step. Those symbols are markup meant for a renderer: once rendered, a hash becomes a large heading and asterisks become bold text and bullet points, while the symbols themselves disappear. Double-clicking into Notepad shows you the markup itself. The file is not corrupted — the rendering step is simply missing.
Which way of opening it should you pick?
If you write and keep notes long term, installing Typora, Obsidian or VS Code is the right call — they give you editing, backlinks and plugins. If someone just sent you a .md file and you only want to see what is in it, installing software for that is a poor trade: drop the file onto this page instead, and it renders inside your own browser with no sign-up and no upload. If you then need to hand it to a colleague who doesn't read Markdown, exporting a copy with Markdown to Word / PDF is the easier route.
Can you open .md on a phone?
Phones ship with no app associated with Markdown, so tapping a .md file usually gives you a "cannot open" message, or shows the raw symbols as text. This page works in a mobile browser too: save the .md file from your chat app or cloud drive to the phone, pick it here, and you get the rendered layout.
