About the Online HTML Formatter
The Online HTML Formatter helps you turn messy or compact HTML code into a cleaner, easier-to-read format. Paste your HTML, choose the indent size, and format it with clear line breaks and consistent spacing.
• Features
HTML Formatting: Adds readable indentation and line breaks to make HTML structure easier to follow.
Adjustable Indentation: Choose the number of spaces used for indentation to match your preferred coding style.
Readable Output: Makes nested tags, attributes, and text content easier to review, copy, and edit.
Simple Scope: This tool formats HTML for readability. It is not a validator, sanitizer, or automatic HTML repair tool, so review the code separately when correctness or security matters.
