How do I open a .md file?

Download Markdific, then double-click any .md file or drag it into the window. Markdific opens markdown files instantly and displays headings, tables, code, and images the way they were meant to look.

A .md file is a markdown file: a plain text document that uses simple symbols for formatting. AI tools like ChatGPT, Claude, and Gemini export their answers as markdown, which is why you see more .md files than ever.

Is Markdific a free md file viewer?

Yes. You can open and read any markdown file for free. Every premium feature is free for 14 days, then editing, saving, and export to PDF, Word, and HTML move behind a one-time $12.99 purchase. No subscription.

Does Markdific work on Mac, Windows and Linux?

Yes. Markdific runs on macOS 11 or later (Apple silicon and Intel), Windows 11 and Windows 10 version 1809 or later, and Linux (.deb, .rpm and AppImage, x64 and ARM). iOS and Android versions are coming soon.

Can I edit markdown files, or only view them?

Both. Markdific is a full markdown reader and editor. View a file, make quick edits, and save without breaking your formatting.
