Frequently Asked Questions
How does the HTML formatter work?
The formatter adds line breaks after block-level tags (div, p, h1-h6, ul, ol, li, table, section, etc.) and indents child content. Inline tags (span, a, strong, etc.) are preserved on the same line. You can choose tab or space indentation.
What tags are considered block-level?
Block-level tags include: html, head, body, div, p, h1-h6, ul, ol, li, table, tr, td, section, header, footer, nav, main, article, aside, form, and more. Content in pre tags is preserved as-is.
Does it detect HTML errors?
The formatter performs basic structure formatting. It does not validate HTML — it simply organizes the markup with proper indentation. Use an HTML validator for error checking.
Is my HTML sent to a server?
No. All formatting happens entirely in your browser. Your code never leaves your device.
How does the Smart Indentation feature work?
The Smart Indentation feature auto-indents nested html tags with configurable tab or space indentation. It is designed to be intuitive and responsive, giving you immediate feedback as you interact with the tool. All processing happens locally in your browser.
What is the benefit of tag cleanup?
Tag Cleanup removes unnecessary whitespace between tags while preserving content. This capability sets HTML Formatter apart from basic alternatives by providing more comprehensive functionality while maintaining the privacy and speed of local processing.
Is HTML Formatter really free to use?
Yes, HTML Formatter is completely free with no hidden charges, no sign-up requirements, and no usage limits. You can use it as often as you need, for any purpose — personal projects, commercial work, or educational use. There are no premium tiers or paid features.
Does HTML Formatter work on mobile devices?
Yes, it works on any device with a modern web browser — desktop, tablet, or phone. The interface is responsive and adapts to your screen size. Since all processing is done locally, you get the same performance regardless of your device.
