Why Format Your HTML?
Minified HTML is great for production, but unreadable during development. Formatting adds consistent indentation and line breaks so you can quickly understand the document structure.
What formatted HTML means for you
- Clear structure: Properly indented tags make parent-child relationships obvious.
- Consistent style: Enforce the same formatting across your entire team.
- Better diffs: Formatted HTML produces cleaner version-control diffs.
- Faster onboarding: New team members can understand the codebase faster.
Safe formatting
Toolza never changes the meaning of your HTML — only whitespace is adjusted. Attributes, inline styles, and embedded scripts remain untouched.
