ℹ Info

What it does

JS minification reduces file size by stripping comments and whitespace the browser does not need to execute the script.

Smaller JS files parse faster and reduce bandwidth costs significantly.

Optimizations

✓ Strip // line comments
✓ Strip /* block comments */
✓ Collapse multi-space runs
✓ Remove blank lines
✓ Spaces around operators
✓ Preserves string literals

Note

This is a whitespace/comment minifier. For full variable renaming and dead-code elimination, use a build tool like Terser or esbuild in your pipeline.
