List markers, heading spacing, emphasis style, code fences and line wrapping — the same output Prettier gives in editors.

Whether long paragraphs are re-wrapped to your line width, left as-is, or kept on single lines.

No. Prettier loads into your browser and formats locally.

About this tool: Markdown Formatter

Clean Markdown with a live preview

The Markdown Formatter formats Markdown source and renders it side by side: beautify mode normalises heading spacing, list markers and emphasis syntax into consistent style, while the live preview shows exactly how your document will read on GitHub, documentation sites and chat platforms.

Markdown's tolerance is its trap — the same document can use asterisks or underscores, tight or loose lists, and still render, but inconsistently across renderers and unreadably in source. Normalising syntax keeps a documentation codebase maintainable, and the preview catches broken links and tables before publication.

Everything renders locally in your browser. Draft READMEs, changelogs, documentation pages and rich chat messages with instant visual feedback, then copy either the clean source or publish-ready text.

Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
