About this HTML attribute sorter and cleaner

This tool helps clean HTML snippets by sorting attributes into a predictable order, normalizing class attributes, and removing empty utility attributes.

It is useful when reviewing copied markup, cleaning component templates, or making generated HTML easier to scan in code review.

How to use it

  1. Paste an HTML fragment, component, or small template into the input field.
  2. Choose which cleanup options should run.
  3. Click Clean HTML and copy the cleaned output.

Tips

  • Sorting attributes makes repeated components easier to compare.
  • Class normalization removes extra whitespace and can remove duplicate class names.
  • Empty boolean attributes such as disabled or checked are preserved.
  • The markup is parsed locally in your browser and scripts are not executed.

HTML attribute sorter FAQ

Does this change how my HTML renders?
The tool is designed for safe cleanup, but always review the result when working with framework-specific syntax.
Which empty attributes are removed?
It removes empty class, id, style, title, data-* and aria-* attributes. Boolean attributes are preserved.
Does it support Vue, Alpine, or Angular attributes?
Standard HTML attributes are handled best. Framework-specific shorthand syntax may be normalized by the browser parser.

No. The cleanup runs locally in your browser.
