How do I open a .md file online?
A .md file is plain text in Markdown format. Drop it on this page (or any text editor opens it raw) — this online MD viewer renders it formatted: headings, tables, code, and math, the way it's meant to be read. No install, no signup.
Is this MD viewer free?
Yes. It is a free online MD viewer and reader: no account, no install, and no limit on how many files you open. It runs in your browser, so it works the same on Windows, Mac, Linux, and Chromebooks.
Is my file uploaded to a server?
No. The viewer runs entirely in your browser — the file is read locally and rendered locally. It never leaves your device unless you explicitly export to DOCX (which briefly uses our converter and stores nothing).
What Markdown features does the viewer render?
GitHub Flavored Markdown: tables, task lists, strikethrough, fenced code blocks with syntax highlighting for major languages, plus inline $…$ and block $$…$$ LaTeX math rendered as real equations.
Can I edit the Markdown too?
Yes — switch the workspace to Split or Editor view and the same document is editable with a live preview, a formatting toolbar (bold, italic, code, links, headings, lists, tables), and ⌘/Ctrl+B/I/K shortcuts. The viewer, editor, and converter are one tool.
Can I turn the .md file into a Word document or PDF?
One click. DOCX arrives with native Word tables and editable Office Math equations — the part most viewers and converters skip. PDF and HTML render right in your browser, or use the Print button.
How do I open a .md file on Windows or Mac without installing anything?
Use this page — it works in any modern browser on Windows, macOS, Linux, and mobile. Bookmark it and drop files in whenever a README or AI-exported .md lands on your desk.
Can I use this as a README viewer?
Yes — README.md is just a Markdown file. Drop it here and it renders the way GitHub would show it: headings, tables, task lists, badges-as-images, and fenced code with syntax highlighting. Handy for reading a project's README from a ZIP download without opening an editor.
