Frequently Asked Questions
Is this code minifier free?
Yes, completely free with no signup, no ads, and no file limits.
Is my code sent to a server?
No. All minification runs entirely in your browser using JavaScript. Your code never leaves your device.
What languages are supported?
JavaScript (using Terser), CSS, and HTML. Each language uses optimized minification that preserves functionality while removing whitespace, comments, and unnecessary characters.
Can I minify multiple files at once?
Yes. Drag and drop multiple .js, .css, or .html files onto the upload zone to batch-minify them all at once with per-file size savings.
