Frequently Asked Questions

Does formatting change how HTML renders?+
In most cases, no. Browsers ignore extra whitespace in HTML. The only exception is within <pre> tags and elements with white-space: pre CSS, where spacing is preserved. This tool handles <pre> blocks specially.
Should I minify HTML for production?+
Minifying HTML can save 10–30% of file size, but the impact is small compared to minifying CSS and JavaScript, and even smaller with gzip compression enabled. It's a nice optimization but not critical for most sites.
