Frequently Asked Questions
What is code minification?
Code minification removes unnecessary characters — whitespace, comments, line breaks — from source code without changing its functionality. This reduces file size and improves page load times.
Is my code stored or sent to a server?
No. All processing happens locally in your browser using JavaScript. Your code never leaves your device, ensuring complete privacy and security.
What languages are supported?
Code Minifier currently supports JavaScript (.js), CSS (.css), and HTML (.html) minification and beautification. More languages may be added in the future.
