^{minification benchmarks}

What's the best JavaScript minifier?

This project benchmarks the following minifiers:

babel-minify _v0.5.2
bun _v1.1.34
esbuild _v0.24.0
google-closure-compiler _{v20240317.0.0}
tedivm/jshrink _v1.7.0
@swc/core _v1.9.2
@tdewolff/minify _v2.21.1
terser _v5.36.0
uglify-js _v3.19.3

Benchmarks last updated on Nov 11, 2024.

🙋‍♂️ Why?

To help you pick a minifier that fits your needs
To promote JS minifiers and document their performances
To encourage healthy competition and improvement amongst minifiers

👟 Methodology

Each minifier is executed in its own process with a 10s timeout
Artifact integrity is verified by a test before and after minification
Minifier upgrade PRs are automated via WhiteSource Renovate
Benchmarks are updated on every PR via GitHub Actions

⏱ Metrics

Minifiers are ranked by smallest minzipped size.

Minified size

Size of the minified output.

Minzipped size

Size of the minified output with Gzip compression.

For minifiers, this measures how compressable the output is.

For users, this measures network transfer size, which is usually the metric that matters most.

Time

How long minification took (average of 5 runs). Each time is annotated with a multiplier relative to the fastest minifier.
