Why Format HTML?
Well-formatted HTML is easier to read, debug, and maintain. Consistent indentation reveals the document structure at a glance, making it faster to spot nesting errors and understand layout relationships.
When working with server-rendered templates or minified production builds, an HTML formatter restores readability in seconds. The Code Formatter handles multiple languages, but this dedicated HTML tool adds tag validation and one-click minification.
