How to use HTML Beautifier
- Paste the HTML snippet or upload a page source file that needs formatting.
- Run the beautifier and check the indentation around nested sections, tables, forms, and inline blocks.
- Copy the formatted result into your editor or download the cleaned HTML file.
Why use HTML Beautifier
A readable HTML file makes template debugging much faster. When markup has been copied from a minified page, a CMS block, an email builder, or a legacy theme, formatting reveals the real structure so closing tags and repeated wrappers are easier to spot.
The beautifier is especially helpful before comparing two page versions or extracting a section into a reusable component. It does not rewrite your document into a new framework; it simply gives the existing markup breathing room so you can make better edits.
Best for HTML Beautifier
- Unminifying page source copied from a browser.
- Reviewing CMS templates, email snippets, and embedded widgets.
- Preparing HTML for a cleaner code review or diff.
Practical notes
- Validate important pages after formatting if the source was already broken.
- Keep scripts and preformatted content in mind when reviewing the output.
- Use the result as a readable working copy before making structural changes.
