Frequently Asked Questions

Does this tool validate HTML?

The tool focuses on formatting and indentation. While it handles most HTML correctly, it is not a full HTML validator — use the W3C validator for compliance checking.

Can I format XML with this tool?

Yes. The formatter handles both HTML and XML markup using the same indentation and nesting logic.

Is my HTML sent to a server?

No. All formatting happens entirely in your browser. Your markup never leaves your device.

Does it preserve inline JavaScript and CSS?

Yes. Script and style block contents are preserved as-is while the surrounding HTML structure is reformatted.
