What the HTML Minifier does
The HTML minifier reduces the size of your HTML by removing comments, unnecessary whitespace and redundant characters, which helps pages load faster.
How it works
The tool parses your HTML and removes comments, collapses whitespace between tags, and trims other non-essential characters without changing how the page renders.
Smaller HTML means less data to download and parse, which contributes to better Core Web Vitals and a faster experience for users.
