HTML Minifier

Runs entirely in your browser — your code is never uploaded to a server. Performs safe, conservative minification: strips comments and collapses whitespace to single spaces, but deliberately does not remove all whitespace between tags — inter-element whitespace can be visually significant for inline elements (e.g. a space between two <span>s), so this preserves it rather than risk merging visible text together. Content inside <script>, <style>, <pre>, and <textarea> is preserved exactly, untouched.
