HTML Beautifier
Format messy HTML with clean, consistent indentation.
Beautify and Indent HTML
Minified or machine-generated HTML is almost impossible to read. This beautifier re-indents your markup so nested elements line up cleanly, making structure obvious and debugging easy.
What it does
- Puts each tag on its own line
- Indents children under their parent
- Recognises void elements like <img> and <br>
- Preserves <pre>, <script>, and <style> content
Great for debugging
When you copy HTML from a built bundle or a browser's view-source, beautifying it first lets you read the DOM hierarchy and spot unclosed or misnested tags.
Readable code, fewer bugs
Consistent indentation is not just cosmetic â it makes missing closing tags and incorrect nesting jump out visually. Beautified HTML is also far easier to review in pull requests and to hand off between team members.
