Why Markdown Lens?
Most markdown tools try to do everything—edit, sync, organize, collaborate.
They're bloated, expensive, or abandoned.
Markdown Lens does one thing exceptionally well:
Preview your Markdown Files Beautifully.
Actually Free
Not "free with limits." Not "free trial." Every feature works, forever. An optional tip jar supports development.
No Ads. Ever.
No banners. No popups. No "upgrade to remove ads." Just your markdown, beautifully rendered.
PDF Export That Works
Clean exports with proper page breaks and sensible margins. No more wrestling with print settings.
Microsoft Word Export
Generate native .docx files with tables, images, code blocks, math, and diagrams. Share with anyone.
Native macOS Citizen
Launches instantly. Respects Dark Mode. Opens from Finder. Built specifically for your Mac.
Works With Your Editor
Keep using VS Code, Vim, BBEdit, or whatever you love. Markdown Lens refreshes automatically.
Modern Markdown
Math equations, Mermaid diagrams, syntax highlighting for 190+ languages. All built-in.
Private & Actively Maintained
No accounts, no analytics, no cloud—your files never leave your Mac. Regular updates and improvements, not abandonware.
