Paste the Markdown draft
Start with the Markdown that already exists but still needs cleanup.
Free • Fast • No Registration Required
Format Markdown so the document reads cleanly again.
This route focuses on structural cleanup: spacing, list consistency, blank lines, and mixed-language readability. It is for polishing Markdown, not converting another source format.
Optimizer
Clean up Markdown before you publish it.
What it fixes
- Blank line normalization
- LaTeX delimiter cleanup
- List bullet unification
- CJK and Latin spacing
Why Use This Tool?
The content is already Markdown, but the document still feels messy. Blank lines are inconsistent, lists switch bullet styles, math delimiters are awkward, and mixed CJK/English text looks cramped.
That kind of cleanup is too small for a full rewriting workflow and too annoying to do manually every time. This page gives that polishing step its own focused tool.

Frequently Asked Questions
What does this Markdown formatter normalize?+
It cleans blank-line rhythm, normalizes LaTeX delimiters, unifies list bullet characters, trims trailing whitespace, and can add CJK/English spacing for mixed-language writing.
Does it rewrite the meaning of the document?+
No. The formatter is focused on structural cleanup and readability. It does not summarize or paraphrase the content.
Why is CJK spacing optional?+
Some teams want pan-Asian spacing rules between Chinese, Japanese, Korean text and Latin words or numbers, while others prefer to keep the original style. The toggle lets you decide.
