What is JS Compressor?

JS Compressor is a free, browser-based JavaScript minifier that reduces the size of your JS files instantly. Smaller files mean faster page loads and better SEO scores.

Remove comments — strips single-line // and block /* */ comments while preserving licence blocks (/*!).
Strip whitespace — collapses spaces, tabs and newlines without breaking your code.
Remove console.log — deletes all debug logging calls before shipping.
Remove debugger — cleans up forgotten debugger statements.
Drop optional semicolons — removes redundant semicolons before closing braces.
Beautify / Format — pretty-prints minified code back into readable form.

All processing happens entirely in your browser. Your code is never sent to any server.
