JavaScript Minifier Tips

Powered by Terser - the same engine behind webpack, Vite and Rollup production builds.
Mangling renames local variables to short names; disable it if you need readable stack traces.
Dead code like unused functions is dropped automatically by the compressor.
Minified ES modules still need a bundler for import/export resolution - minify bundles, not modules.

Terser Engine

The same battle-tested minifier that powers production builds of webpack and Vite.

Dead Code Removal

Unused variables, unreachable branches and redundant logic disappear automatically.

Mangle Control

Toggle variable mangling with one checkbox - readable when you need it, tiny when you ship it.

Size Report

Bytes before and after, plus the exact percentage saved, on every run.

Private by Design

Your source code stays in the browser tab. Nothing is uploaded, ever.

Sıkça Sorulan Sorular

Js Minifier biçimlendirme hakkında yaygın soruların cevapları

Yes, completely free with no registration. All minification happens locally in your browser.

Terser - the industry-standard minifier used by webpack, Vite, Rollup and many other bundlers for their production builds.

Mangling renames local variables and functions to 1-2 character names for extra savings. Enable it for production; disable it when you need readable stack traces or debug the output.

It can compress the syntax, but module specifiers are left as-is. Bundle your code first (e.g. with a bundler), then minify the bundle for the best result.

Typical well-commented, readable source shrinks 40-60% with mangling enabled; already-compact code shrinks less. The size report shows the exact savings.
