FAQ
HTML minification removes comments, extra whitespace, newlines, and redundant attributes like type="text/javascript". The result is a smaller HTML file that loads faster without any change to how the page renders.
For standard HTML, minification is safe. The one edge case is whitespace between inline elements — for example, a space between two <span> tags may be removed. Most layouts are unaffected, but check your output if you rely on inline element spacing.
Typical savings are 10–30% for hand-authored HTML. Pages with many comments, verbose attribute values, or heavy indentation can shrink by 40% or more. The savings counter shows the exact reduction for your file.
Use Beautify when you receive minified HTML (from a CMS, build tool, or third-party template) and need to read or debug it. It adds consistent indentation and line breaks to make the markup human-readable again.
