Markdown Formatter is a browser-based Markdown Formatter that uses Prettier to format Markdown text. It normalizes lists, code blocks, and prose wrapping so documents and snippets are easier to read and review. Paste or drop in Markdown, choose the available options, and use the formatted result in your project.
The formatter provides configurable print width and prose wrap, along with indentation options. These settings affect how Markdown is arranged in the output. The tool formats Markdown rather than converting it into a different markup language, helping keep source files consistent across documentation, reports, and code reviews.
Markdown is a plain-text format that uses lightweight syntax for elements such as lists and code blocks, and it can be rendered as a formatted document. Its source is useful for editing and version control, but inconsistent spacing and wrapping can make changes harder to review. Formatting the source gives developers a more uniform starting point and can reduce whitespace differences in diffs.
Markdown Formatter runs entirely in your browser. The input is processed on your device and is not uploaded, stored, or sent to a server; once the page has loaded, the tool works offline. It is free to use, and no signup is needed to format Markdown.
Developers and DevOps engineers can use the formatter when preparing project documentation, cleaning up generated Markdown, reviewing unfamiliar files, or sharing snippets with teammates. It is useful for both quick formatting tasks and keeping Markdown content consistent as part of everyday development work.
Step 1: Paste or drop your Markdown into the tool. The formatter accepts Markdown content as input.
Step 2: Choose the formatting options you need. You can configure print width and prose wrap, and select indentation options.
Step 3: Run the formatter to normalize the Markdown. Lists, code blocks, and prose wrapping are formatted with Prettier.
Step 4: Review the result and check for any parsing issues. If the input does not parse cleanly, use the reported line to locate the problem.
Step 5: Copy the formatted output into your document, repository, bug report, or code review.

Use case: Bring a Markdown document you did not write in line with your team's formatting conventions. A consistent layout makes it easier to compare the content with the style you follow.
Use case: Reduce whitespace noise in diffs by producing consistently formatted Markdown. This helps reviewers focus on meaningful content changes.
Use case: Clean up a Markdown snippet before adding it to a bug report or code review. Formatting makes the snippet easier for other developers to scan.
Use case: Check whether Markdown input parses cleanly and locate the line associated with a parsing problem. This can help you find issues before sharing or committing the document.
Use case: Set prose wrapping to suit the way you want Markdown text arranged. This is useful when preparing documentation for editing or review.
Use case: Normalize lists and code blocks in project documentation. Consistent formatting can make long Markdown files easier to maintain.
