Frequently Asked Questions
What is Markdown?
Markdown is a lightweight markup language using plain-text symbols (like # for headings and ** for bold) that converts to formatted HTML.
How to preview Markdown formatting in real time?
Type or paste your Markdown into the left panel and the rendered HTML preview updates instantly on the right.
What Markdown syntax is supported in the previewer?
The previewer supports GFM (GitHub Flavored Markdown) — headings, lists, tables, code blocks, blockquotes, links, images, and strikethrough.
What is the difference between Markdown and HTML?
Markdown is a simpler shorthand that compiles to HTML — it's easier to write but less expressive than raw HTML.
How to add a table in Markdown?
Use pipe characters to separate columns and a line of dashes for the header separator, e.g. | Col1 | Col2 | on one line and |---|---| below it.
Where does Markdown rendering happen — in the browser or on a server?
In the browser — the marked.js library runs client-side, so your Markdown is never sent to a server.
