About This Tool
Markdown Live Preview is a split-pane editor that renders your Markdown content in real time as you type. The left pane is a plain-text editing area with monospace font and comfortable line spacing, while the right pane shows a fully styled HTML preview that updates on every keystroke. There is no lag and no button to click — the preview is always in sync with your input, making it easy to spot formatting errors the moment they happen.
A compact toolbar above the editor gives you one-click insertion of the most common Markdown formatting: bold, italic, heading levels H2 and H3, hyperlinks, unordered lists, inline code, and fenced code blocks. The toolbar operations are selection-aware — if you have text highlighted in the editor, it wraps the selected text in the chosen formatting syntax rather than replacing it with placeholder text. This makes the toolbar genuinely useful rather than just decorative.
The preview renderer supports headings, bold and italic emphasis, strikethrough, inline code, fenced code blocks with dark-theme styling, blockquotes, ordered and unordered lists, horizontal rules, hyperlinks, images, and GitHub Flavored Markdown pipe tables with column alignment. Everything runs client-side with no external dependencies. The tool is ideal for writing README files, documentation, blog drafts, or any long-form content that will ultimately be published through a Markdown pipeline.
