HTML Formatter Online is a free browser-based tool for cleaning, formatting, and organizing HTML code. Paste messy or minified markup into the editor and turn it into structured HTML that is easier to read, review, and edit.
Use the HTML beautifier to add consistent indentation to nested tags and attributes. The HTML pretty print option makes complex markup easier to understand, especially when working with long HTML documents or code copied from another source.
If you need to quickly format HTML online, you can paste your code, choose 2 spaces, 4 spaces, or Tab indentation, and generate the formatted result. You can also use the HTML formatter in Minify mode when you want a more compact version of your markup.
All pasted HTML is processed in your browser. For public webpages, the Fetch URL option can retrieve the page for formatting.
