Frequently Asked Questions
Why minify HTML?
Minifying HTML reduces the file size of web pages by removing whitespace, comments, and other unnecessary characters that have no effect on rendering. Smaller HTML files transfer faster over the network, reducing page load time and improving Core Web Vitals scores. For high-traffic sites, even small reductions in HTML size can have a significant cumulative impact.
What does "collapse whitespace" do?
Collapsing whitespace removes all whitespace between HTML tags (the spaces, tabs, and newlines used for indentation) and replaces multiple consecutive spaces in text with a single space. This is safe for the vast majority of HTML, but should be used carefully with pre-formatted elements like <pre> and <code> that rely on exact whitespace.
HTML Minifier vs HTML Formatter — when to use each?
Use the HTML Formatter during development to make markup readable and easy to debug. Use the HTML Minifier for production output when you want to reduce file size. A typical workflow: develop with formatted HTML, minify as part of your build process before deploying to production.
