Tool Overview
HTML has a habit of becoming a jungle of tags, especially after a few rounds of editing or when code comes from different sources. This HTML tool helps bring some order back to your markup. Clean up the structure, check for common syntax issues, or make the final HTML more compact when you're ready to use it in a project.
What can you do?
- 1. Format HTML
Turn cramped or poorly structured markup into a clean, readable layout with consistent indentation. Nested elements become easier to spot, making the document simpler to work with and maintain. - 2. Validate HTML
Check your markup for common structural and syntax problems, including unclosed tags, incorrectly nested elements, and other issues that can cause unexpected results in the browser. - 3. Minify HTML
Remove unnecessary whitespace, line breaks, and comments to produce a more compact HTML document. This is useful when you want to trim down markup before putting it into a production environment. - 4. Copy the result
Finished cleaning up your markup? Copy the processed HTML and paste it directly into your project, template, or wherever you need it.
Why use this HTML tool?
HTML is usually easy to write, but large documents can become surprisingly difficult to navigate once elements start nesting several levels deep. Formatting gives you a clearer picture of that structure, while validation helps uncover markup mistakes that might otherwise turn into strange browser behavior. When readability takes a back seat to file size, minification can remove the extra characters you don't need. Clean it up, check it, shrink it, and get on with building the page.
