What does minifying HTML do?

Minifying HTML reduces file size by removing unnecessary characters like comments and extra whitespace. Smaller HTML can improve load times and reduce bandwidth usage.

Can minifying HTML change how a page looks?

Safe minification typically preserves rendering. Aggressive whitespace removal between tags can change rendering for inline elements when spaces are meaningful.
