Frequently Asked Questions
What is an HTML formatter?
An HTML formatter is a tool that automatically formats HTML code with proper indentation and line breaks. It transforms messy, minified, or poorly formatted HTML into clean, readable markup that's easier to understand and maintain.
Does this preserve script and style content?
Yes, the formatter preserves the content inside <script> and <style> tags. It doesn't modify the JavaScript or CSS code within these tags to avoid breaking your functionality. Only the HTML structure outside these tags is reformatted.
What's the difference between beautify and minify?
Beautify expands HTML with proper indentation and line breaks, making it readable for developers. Minify removes all unnecessary whitespace, comments, and line breaks to create the smallest possible file size, which is ideal for production websites.
Can this validate HTML?
Yes, the tool includes basic HTML validation that checks for common issues like unclosed tags, mismatched tag names, and invalid nesting. However, for comprehensive W3C validation, we recommend using the official W3C Markup Validation Service.
Is my HTML data secure?
Yes, completely. All formatting happens 100% in your browser using JavaScript. Your HTML never leaves your device and is not sent to any server. This makes it safe to format any HTML, including pages with sensitive information.
