What Is a Markdown File?
Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple plain-text formatting syntax — # headings, **bold**, *italic*, [links](url), and `code` — that converts to HTML. Files typically use the .md or .markdown extension.
Markdown is the standard for README files on GitHub, technical documentation, blog posts, and personal notes. Our free Markdown Viewer renders your .md files with beautiful typography, styled code blocks, formatted tables, and proper list indentation — all without uploading your data anywhere.
Use the viewer to preview README files before pushing to GitHub, review documentation from colleagues, check blog post formatting, or simply read Markdown files with full rendering. Switch to source view to inspect the raw syntax with line numbers.

Fenced code blocks are displayed with a dark theme, monospace font, and horizontal scroll for wide content.

GFM tables render with borders and header styling. Ordered and unordered lists display with proper indentation.
