What is it?
Markdown is a lightweight markup language created by John Gruber in 2004, with input from Aaron Swartz, designed to be easy to read and write as plain text. Its goal is to let people format text using simple, unobtrusive punctuation that can be converted to structurally valid HTML.
A Markdown document is just plain text with conventions: hash marks for headings, asterisks or underscores for emphasis, hyphens for lists, and brackets for links. A processor converts these cues into HTML (or other formats). The IETF registered the text/markdown media type in RFC 7763 (2016), and the CommonMark project provides a precise, widely adopted specification.
Technical Specifications
Pros & Cons
Advantages
Markdown source is easy to read and write even before conversion, unlike HTML or XML markup.
Files are plain text, so they work in any editor and play well with version control systems like Git.
Markdown can be rendered to HTML and, via tools like Pandoc, to PDF, DOCX, and more.
It is the default for READMEs, documentation, and many writing and note-taking platforms.
Disadvantages
Many flavors (CommonMark, GitHub Flavored Markdown, and others) differ in features, causing inconsistencies.
Core Markdown lacks tables, footnotes, and complex layout, which require extensions or raw HTML.
Markdown describes structure, not precise visual layout, so it is unsuitable for pixel-level design.
When to Use It
Markdown is used wherever lightweight, readable text formatting is valuable.
软件文档
READMEs, wikis, and docs on platforms like GitHub and GitLab are typically written in Markdown.
笔记和写作
Note-taking and writing apps use Markdown so authors can format text quickly with plain keystrokes.
静态网站内容
Static site generators convert Markdown source files into HTML pages for blogs and websites.
How to open a MARKDOWN file
Markdown editing tools can be categorized into professional applications, free and open-source software, browser-based editors, and built-in options within other software. Professional applications like Typora and Obsidian cater to users who require advanced features and a polished interface, while free and open-source options like Visual Studio Code and Joplin appeal to budget-conscious users or developers. Browser-based editors provide convenience and accessibility, making them suitable for quick edits or collaborative work. Built-in Markdown support in applications like Notion or Word offers basic functionality for users who need Markdown occasionally without dedicated software.
When choosing a Markdown tool, users should consider factors such as feature fidelity, the distinction between editing and viewing modes, cost models, and platform compatibility. Some applications excel in real-time preview capabilities, while others focus on extensive editing features. Export needs are also critical; users may require outputs in formats like HTML or PDF, which can influence the choice of software. In some cases, converting Markdown to other formats may be necessary, so understanding the conversion capabilities of each tool is essential.
