SnapToolsMarkdown Formatter
Runs in your browserFormat Markdown with consistent heading, list, and emphasis syntax, and cleaned-up spacing — useful for READMEs edited by more than one person.
About this tool
Markdown looks simple but drifts fast across a document with multiple contributors: some use * for bullets, others -, some use __bold__ and others **bold**. This tool runs the same Markdown printer Prettier ships, normalising heading, list, and emphasis syntax to one consistent style without changing the rendered output.
How to use
- Paste your Markdown.
- Run the formatter.
- Copy the normalised result.
When to use this tool
- Normalising a README edited by multiple contributors with inconsistent styles.
- Cleaning up spacing and list markers before committing documentation.
- Standardising heading and emphasis syntax across a document.
Tips
- Formatting doesn't change how the Markdown renders — only its underlying syntax and spacing.
- Run this before a diff review — a consistent style keeps future diffs to actual content changes.
FAQ
- Will this change how my document looks when rendered?
- No. It normalises the underlying syntax (list markers, emphasis characters, spacing) without changing the rendered output.
- Is my document sent anywhere?
- No. Formatting runs entirely in your browser using Prettier.
