What is the Markdown Previewer?
The Markdown Previewer is a fast, browser-based editor and live renderer for GitHub Flavored Markdown (GFM).
Markdown is the standard lightweight markup language used for GitHub `README.md` files, documentation, blog posts, and technical writing. This tool renders your raw Markdown side-by-side in real time with support for headings, tables, task lists, code blocks, blockquotes, and links.
Key Features
- Real-Time Split View: See rendered HTML side-by-side with your raw Markdown input as you type.
- GFM Compliant: Full support for tables, task checkboxes (`[x]`), strikethrough (`~~text~~`), blockquotes, and fenced code blocks.
- Export Options: Copy generated HTML output, download as `.html`, or download as `.md` file.
- Word & Character Counters: Displays paragraph count, word count, character count, and reading time estimate.
- Sample Document Loader: Load a rich Markdown template to test all formatting elements.
How Does the Markdown Previewer Work?
1. Type or Paste Markdown into the left editor pane.
2. Observe Live Preview: The right pane updates instantly with formatted HTML styling.
3. Copy or Export: Click Copy HTML or Download .html / .md file.
