HTML Minifier
Compresses HTML by stripping comments, collapsing whitespace, and removing gaps between adjacent tags — while preserving <pre>, <textarea>, <script>, and <style> contents — with a live before-and-after byte size comparison and a one-click copy, useful for shrinking static pages, email templates, and embedded markup without changing how they render.
