How do I make text bold or italic in Markdown?

Wrap text in single asterisks or underscores for italic (*italic* or _italic_), double for bold (**bold**), and triple for both (***bold italic***). Strikethrough uses double tildes (~~text~~) in GitHub Flavored Markdown.

How do I write a table in Markdown?

Use pipes to separate columns, for example | a | b |, then add a separator row of dashes (| --- | --- |) below the header row. Each following row is a data row. Tables are a GitHub Flavored Markdown feature.

Is any data sent anywhere?

No — this is a static reference that runs entirely in your browser. Nothing is uploaded.

How do I add a link or an image in Markdown?

A link is [text](url), and a link with a hover title is [text](url "title"). An image is the same with a leading exclamation mark — ![alt text](url). A bare URL in angle brackets, , becomes a clickable autolink.

How do I write a code block in Markdown?

Wrap a single span in backticks for inline code (`code`). For a block, put three backticks on their own line before and after the code. Add a language after the opening fence (```js) so renderers apply syntax highlighting. Indenting four spaces also makes a code block.

What is GitHub Flavored Markdown?

GitHub Flavored Markdown (GFM) is a superset of standard Markdown that adds tables, task lists ( - [ ] and - [x] ), strikethrough (~~text~~) and autolinking. This reference flags GFM-only items so you know which features may not render in stricter Markdown engines.

How do I create a task list checkbox?

Use a list item with a bracketed space for unchecked ( - [ ] task ) and a bracketed x for checked ( - [x] task ). These render as interactive checkboxes on GitHub and other GFM-aware platforms.

What is the Markdown Syntax Reference?

A searchable Markdown syntax reference — headings, emphasis, lists, links, images, code blocks, tables and more — with plain-English meanings. Runs entirely in your browser. It runs free in your browser on Gera Tools, with nothing uploaded.

Markdown is the lightweight plain-text formatting language behind GitHub READMEs, Reddit comments, Notion, Discord and countless docs tools. This searchable cheat sheet lists the syntax for headings, emphasis, lists, links, images, code, blockquotes and tables, each with a plain-English explanation, plus the common GitHub Flavored Markdown (GFM) extras. It’s a reference, not a converter — use it to look up the exact characters when you can’t remember them.

How it works

The entries are grouped into sections — Headings, Emphasis, Lists, Links & images, Code and more — and each row pairs the literal Markdown syntax with what it produces. Type a keyword or symbol in the search box (for example bold, table, link, ~~ or code) and the list filters live to matching entries. There is no parsing or rendering of your own text; it is a static lookup table.

Example

Searching bold surfaces the emphasis entries. The reference shows:

You type	You get
`italic`	italic text
`bold`	bold text
`*bold italic*`	bold and italic
`~~strikethrough~~`	struck-through text (GFM)
`[text](url)`	an inline link
`# Heading 1`	a top-level heading

GFM-only items such as tables, task lists and strikethrough are labelled so you know they may not render in stricter Markdown engines. Everything runs in your browser and nothing is uploaded.
