This minifier removes JavaScript comments and collapses whitespace. It's safe for most scripts — for complex production builds consider using build tools like terser/uglifyjs.

How to use

1. Paste JS into the left editor.
2. Click Minify.
3. Use Copy or Download .js.
4. On Blogger: New post → Switch to HTML view and paste the minified script inside <script>...</script> or upload as an external file.
