Online JS Compressor
Maximize your website speed with our online JS compressor. Strip unnecessary bytes from your JavaScript files.
High-Performance JS Compression
Modern web applications rely heavily on JavaScript. As codebases grow, so do bundle sizes. Our Online JS Compressor helps keep your footprint small.
How It Works
The tool parses your code and removes all tokens that are not essential for execution. This includes:
- Developer comments (documentation, TODOs).
- Formatting whitespace (tabs, newlines).
- Redundant semi-colons.
SEO Impact
Google uses page speed as a ranking factor. Large JS files block rendering and increase load time. By compressing your assets, you improve Core Web Vitals, specifically LCP (Largest Contentful Paint) and FID (First Input Delay).
Tips
Always verify the output. While safe, regex-based compression can sometimes be aggressive. Use proper build tools like Webpack or Terser for complex enterprise applications.
