About these tools
The HTML, CSS and JavaScript formatters re-indent minified or messy code so you can read and debug it. They change whitespace and layout only; they do not alter what the code does.
The generators produce the files and tags that help a website get discovered and shared: title and description meta tags, Open Graph and Twitter card tags for link previews, robots.txt crawl rules and XML sitemaps.
Generated tags and files are a starting point. Check them against your site's real URLs and content before publishing.
Frequently asked questions
Will formatting change how my code behaves?
Formatting only changes whitespace and line breaks. It is designed not to change behaviour, but whitespace can matter inside elements such as <pre> or in inline elements, so review the result.
Do meta tags improve search rankings?
The title and meta description help search engines understand a page and can influence how it appears in results, which affects clicks. They do not replace useful content.
