도구 소개

Shrink HTML to its smallest safe form: comments stripped, whitespace collapsed, and blank lines removed — without touching the content of <pre>, <textarea>, <script>, or <style>.

도구 개요

A minifier reduces the bytes a browser has to download by removing characters that do not affect rendering. Comments, runs of whitespace, and newlines between tags are all safe to strip in most documents. This tool walks your HTML, sets aside the contents of preserved tags (<pre>, <textarea>, <script>, <style>) so they survive intact, then collapses whitespace in the rest. Toggle each option to match your stack — keep IE conditional comments, preserve line breaks for readable diffs, or drop empty class="" attributes. Everything runs locally in your browser; nothing is uploaded.

자주 묻는 질문

Will it break <pre> or <script> contents?+

No. The minifier sets those blocks aside before collapsing whitespace, then restores them verbatim, so indentation, code, and styles stay intact.

Does it remove IE conditional comments?+

No. Comments that start with <!--[if are kept so legacy IE conditional logic continues to work.

Is the output safe to deploy to production?+

For most templates, yes — the rules used are conservative. Always run a smoke test of the rendered page after a major minification change.

Is my HTML uploaded?+

No. Minification runs entirely in your browser; nothing leaves your device.
