HTML Minifier: questions

How much does minification save?
Typically 5–25% depending on how much whitespace and how many comments your markup contains. The workbench shows actual byte savings for your pasted HTML.
What does the QA pack include?
It summarizes byte savings, preserved raw-text blocks, removed comments, launch-risk findings, and a starter deploy guard without copying your raw page source.
Does it change scripts or styles?
Script, style, pre, and textarea blocks are protected before whitespace is collapsed so whitespace-sensitive content is preserved for safer production review.
