PrettyMD

Read local Markdown files with tables, highlighted code, math, diagrams and relative images, offline.

Read, edit and export local Markdown files directly in Chrome. PrettyMD turns plain Markdown into a formatted document with clear headings, tables, highlighted code, mathematical equations and diagrams. Open a .md or .markdown file in Chrome to start reading. Features: • Light, Dark and System themes. • A collapsible table of contents with heading navigation. • Syntax highlighting and Copy buttons for code blocks. • KaTeX mathematical equations and Mermaid diagrams. • Relative links and images. • Raw and formatted views. • An editor with live preview. • Save edits to a chosen local file or download a copy. • Export formatted documents through Chrome’s Save as PDF option. Local Markdown rendering, code highlighting, maths and diagrams work offline. Images hosted online require an internet connection. Your original file is not overwritten automatically. Saving first asks you to choose a destination; later saves reuse that chosen file during the session. First-time setup: 1. Open chrome://extensions. 2. Find PrettyMD and click Details. 3. Enable “Allow access to file URLs”. 4. Open a Markdown file using Open With → Google Chrome, drag it into Chrome, or use Chrome’s file picker.
