Frequently asked questions
What is Markdown?
Markdown is a lightweight markup language that lets you format text using plain characters — # for headings, **bold**, *italic*, - for lists, and so on. It converts to HTML and is used in GitHub READMEs, documentation, blog posts, and many writing apps.
What Markdown syntax does this support?
This previewer supports the CommonMark spec: headings (# to ######), bold, italic, strikethrough, inline code, fenced code blocks, blockquotes, ordered and unordered lists, horizontal rules, links, and images.
Does this support GitHub Flavored Markdown (GFM)?
Partially. GFM extensions like task lists (- [ ] item) and tables are rendered. Syntax highlighting inside code fences is not applied — code is displayed in monospace but not coloured.
Can I use this to write README files?
Yes — paste your README here to preview exactly how it will look on GitHub. The rendered output matches GitHub's standard Markdown rendering closely.
Does my text get sent to a server?
No. All Markdown parsing and rendering happens entirely in your browser using a JavaScript library. Your text never leaves your device.
