Markdown Formatter & Previewer
Format Markdown with consistent style and preview the rendered HTML. Great for README files, docs, and content drafting.
Formatted Markdown preview will appear here.
How does the Markdown Formatter & Previewer work?
Paste your Markdown into the input and click “Format Markdown” to clean up spacing, headings, lists, and code blocks using standardized rules. The preview panel renders your Markdown to HTML so you can see how it will look in documentation or on websites.
Formatting uses opinionated defaults for readability—like adding spaces after headings (#), normalizing lists, and wrapping prose where appropriate—so your Markdown is consistent and clean.
Can I customize formatting options?
Yes. You can toggle indentation settings, tab width, and prose wrapping behavior. Choose whether to use tabs or spaces, set print width for line wrapping, and enable or disable comment and whitespace normalization effects.
Is the preview safe from malicious content?
The preview sanitizes rendered HTML to prevent script execution and unsafe attributes. This helps reduce security risks when rendering Markdown from untrusted sources.
What kinds of Markdown are supported?
Common Markdown elements like headings, bold/italic text, lists, code blocks, inline code, links, images, tables, and blockquotes are supported. The preview aims to match typical GitHub-flavored Markdown rendering.
