What is an HTML Formatter?
An HTML Formatter is a tool that transforms unformatted or hard-to-read HTML (HyperText Markup Language) into a clear, indented representation. Especially with large HTML files or complex page structures, a formatter helps you recognize the nesting and hierarchy of elements at a glance. This tool uses Prettier, the widely adopted code formatter, to deliver consistent and professional results. Attributes and nested tags are also cleanly indented, making your markup easy to read and maintain.
How do I use the HTML Formatter?
Paste your HTML into the input field and click "Format" for a nicely indented display, or "Minify" to remove all unnecessary whitespace and line breaks. You can copy the result to your clipboard with a single click. Additionally, you can open the live preview to see the rendered HTML directly in your browser. The preview runs in a secure sandbox environment, so no scripts are executed.
Why format HTML online?
Well-formatted HTML is easier to read, debug, and maintain. Especially when combining HTML from different sources or editing generated code, a formatter saves a lot of time. Minification is useful when you want to compress HTML for emails or embedded templates. Since the tool runs entirely in your browser, no data is sent to any server. Your code remains private and secure on your device, making this ideal for working with sensitive markup.
