What's the best JavaScript minifier?
This project benchmarks the following minifiers:
- babel-minify v0.5.2
- bun v1.1.30
- esbuild v0.24.0
- google-closure-compiler v20240317.0.0
- tedivm/jshrink v1.7.0
- @swc/core v1.7.35
- @tdewolff/minify v2.20.37
- terser v5.34.1
- uglify-js v3.19.3
Benchmarks last updated on Oct 10, 2024.
- 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
- 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
Minifiers are ranked by smallest minzipped size.
Size of the minified output.
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.
How long minification took (average of 5 runs). Each time is annotated with a multiplier relative to the fastest minifier.
