Minifying code is a must for anyone serious about improving web performance and ToolCompanion makes it easy.

Frequently Asked Questions
Q: How do I minify CSS online for free?
Paste your CSS into the Original Code box on ToolCompanion and click Minify now, Copy minified output instantly for free.
Q: Does minifying code break the website or change how it works?
No. Minification removes only whitespace, comments and extra characters. Minification does not alter in any way the logic and functionality of the code.
Q: What is the difference between minification and compression?
Minification is about cleaning up the code itself, getting rid of extra characters. Compression such as Gzip or Brotli is performed at the server level and lessens the size of the file being transferred. Both can be combined for maximum performance.
Q: How much does minifying JS and CSS actually improve page speed?
File size reductions of 20 to 50 percent are common, depending on the amount of whitespace and comments in the original code. Smaller files load faster, and they improve Google PageSpeed and Core Web Vitals scores directly.
Q: Can I minify HTML the same way as CSS and JavaScript?
Yes. Click the HTML tab Paste your markup and click Minify Now. The tool removes inline comments, extra whitespace and unnecessary characters from HTML as it does for CSS and JS.
