Beautify Mode
Beautify lays out attributes on indented lines for readability. Text and whitespace between elements stay unchanged. Preserves content inside pre, code, script, and style tags.
Minify Mode
Minify compacts spacing inside tags while preserving all text and whitespace between elements and optionally strips HTML comments to reduce file size.
HTML Formatting Best Practices
Why Format HTML?
Well-formatted HTML improves readability and makes it easier to spot errors. Indented attributes make complex tags easier to read without changing document text.
Why Minify HTML?
Conservative minification compacts attribute spacing and optionally removes comments. Savings depend on the input; text whitespace is retained to preserve rendering.
Preserved Content
Content inside <pre>,
<code>,
<script>, and
<style> tags is preserved
as-is during formatting to maintain functionality.
Important Note
This tool provides basic formatting. Be careful with inline elements like
<span> and
<a> where whitespace may affect rendering.
Block vs Inline Elements
| Type | Examples | Formatting Behavior |
|---|---|---|
| Block | div, p, section, article, header | Text and spacing preserved |
| Inline | span, a, strong, em, img | Text and spacing preserved |
| Void | br, hr, img, input, meta | Self-closing, no end tag |
| Preformatted | pre, code, script, style | Content preserved exactly |
Common Use Cases

Beautify HTML email templates for editing, then minify before sending to reduce email size and improve deliverability.
CMS Content
Clean up HTML from WYSIWYG editors that often produce messy, poorly formatted markup with excessive whitespace.
Code Review
Format minified HTML from production sites to understand the structure and review the markup for issues.
