## The universal markup converter

Pandoc is a [Haskell](http://haskell.org) library for converting from
one markup format to another, and a command-line tool that uses this
library. It can convert *from*

  - `commonmark` ([CommonMark](http://commonmark.org) Markdown)
  - `creole` ([Creole 1.0](http://www.wikicreole.org/wiki/Creole1.0))

    e-book)
  - `gfm` ([GitHub-Flavored
    Markdown](https://help.github.com/articles/github-flavored-markdown/)),
    or the deprecated and less accurate `markdown_github`; use
    [`markdown_github`](#markdown-variants) only if you need extensions
    not supported in [`gfm`](#markdown-variants).

Pandoc can also produce PDF output via LaTeX, Groff ms, or HTML.

Pandoc’s enhanced version of Markdown includes syntax for tables,
definition lists, metadata blocks, footnotes, citations, math, and much
more. See the User’s Manual below under [Pandoc’s
Markdown](https://pandoc.org/MANUAL.html#pandocs-markdown).

Pandoc has a modular design: it consists of a set of readers, which
parse text in a given format and produce a native representation of the
document (an *abstract syntax tree* or AST), and a set of writers, which
convert this native representation into a target format. Thus, adding an
input or output format requires only adding a reader or writer. Users
can also run custom pandoc filters to modify the intermediate AST (see
the documentation for [filters](https://pandoc.org/filters.html) and
[lua filters](https://pandoc.org/lua-filters.html)).

Because pandoc’s intermediate representation of a document is less
expressive than many of the formats it converts between, one should not
expect perfect conversions between every format and every other. Pandoc
attempts to preserve the structural elements of a document, but not
formatting details such as margin size. And some document elements, such
as complex tables, may not fit into pandoc’s simple document model.
While conversions from pandoc’s Markdown to all formats aspire to be
perfect, conversions from formats more expressive than pandoc’s Markdown
can be expected to be lossy.
