FAQ

Does this tool fix broken HTML tags?

The formatter focuses on indentation and readability rather than error correction. It will format the HTML as-is, and all processing happens entirely in your browser.

Can I format HTML that contains embedded CSS or JavaScript?

Yes. The tool recognizes style and script blocks and formats them appropriately within the HTML structure. All formatting stays in the browser, keeping your code private.

Is there a maximum file size for formatting?

There is no strict limit since formatting runs client-side in your browser. Performance depends on your device, but typical HTML documents are handled instantly and your data stays local.
