Common questions about code minification.
Minification removes unnecessary characters from source code without changing functionality. This includes whitespace, comments, and sometimes shortening variable names. The result is smaller file sizes that load faster.
Yes. Minification only removes unnecessary characters like whitespace and comments. The logic, functionality, and behavior of your code remain exactly the same.
No. All minification happens entirely in your browser using JavaScript. Your source code never leaves your device, making it safe to minify proprietary or sensitive code.
Typical savings range from 10-60% depending on the code. Well-commented code with generous whitespace will see larger reductions. Already-compact code may see smaller improvements.
Currently, the tool processes one file at a time per language tab. You can switch between HTML, CSS, and JavaScript tabs to minify each type separately.
