Mathematical Formula & Explanation

HTML Minification Algorithm: 1. Comment Removal: Regex match and strip  excluding conditional execution tags. 2. Whitespace Normalization: Collapse multiple spaces, newlines, and carriage returns: [ \t\r\n]+ -> ' '. 3. Tag Boundary Trimming: Remove spaces adjacent to opening and closing HTML angle brackets: '> <' -> '><'. 4. Block Element Protection: Retain literal whitespace within <pre>, <code>, and <textarea> containers. Payload Savings (%) = ((Original Size - Minified Size) / Original Size) × 100.
