## What it is
kramdown is a fast, pure-Ruby library for parsing and converting a superset of Markdown (including GFM and PHP Markdown Extra extensions) to HTML, LaTeX, PDF, or back to kramdown. It builds an internal AST that enables multiple input and output formats and also ships a command-line converter.

## Use cases
- convert markdown to html in a ruby app
- render markdown to pdf via latex
- parse github flavored markdown
- use markdown in a static site generator like jekyll
- convert html back to markdown
- strip html tags from markdown documents

## When to choose
- you need a fast, dependency-free pure-Ruby Markdown converter
- you need output formats beyond HTML such as LaTeX or PDF
- you need Markdown Extra/GFM extensions and a strict syntax definition
- you want an AST-based converter you can extend with custom parsers or converters

## When to avoid
- you need CommonMark-spec-exact parsing behavior
- you are not working in Ruby and want a native implementation
- you need streaming or incremental parsing of very large documents

## Facets
- artifact type: library
- maturity: stable
- function: parser, markdown, templating, pdf
- domain: web-development, documentation, files, pdf
- platform: ruby, jvm, cross-platform, cli
- tags: markdown-converter, gfm, latex-output, pure-ruby, jekyll
