Headings (# to ######), bold, italic, strikethrough, inline code, fenced code blocks, links and images, blockquotes, ordered and unordered lists, and horizontal rules. It covers the everyday writing you do in README files, issues, and notes.

About the Markdown Previewer
This tool is a live Markdown editor: you write Markdown on the left and see the rendered HTML on the right, updating with every keystroke. It includes a formatting toolbar, a live word count, and one-click export, so it works as a quick scratchpad for READMEs, documentation, posts, and notes.
What Markdown is and why it helps
Markdown is a lightweight way to write formatted text using plain characters: a hash for a heading, asterisks for emphasis, hyphens for a list. It became the default for developer documentation, GitHub READMEs, issues, chat apps, and static-site content because it is fast to write, readable even as raw text, and converts cleanly to HTML. The catch is that it is easy to make a small syntax mistake — a missing blank line, an unclosed asterisk — that only shows up once it is rendered somewhere else. A live previewer removes that guesswork by showing the result as you type.
What this previewer supports
The converter handles the syntax you reach for daily: headings from level one to six, bold, italic, and strikethrough, inline code and fenced code blocks, links and images, blockquotes, ordered and unordered lists, and horizontal rules. The toolbar inserts the correct syntax around your selection so you do not have to memorise it — select a phrase and click bold, or place the cursor on a line and click heading, quote, or list. A live counter tracks words and characters, useful when a post or description has a length target. Importantly, the preview escapes raw HTML, so pasting a script tag displays it as text rather than running it; you get an accurate preview without the tool becoming a place where pasted content can execute.
Exporting your work
When you are done you have three ways out: copy the rendered HTML to paste into a CMS or email, download your Markdown source as a .md file to keep or commit, or download a complete standalone .html document of the rendered output. Everything runs locally in your browser, so your draft never leaves your device.
