This repo is routinely maintained to compare the quality and speed across the latest versions of the following JavaScript minifiers:
This is fork of the original project which shows the benchmark results with more recent versions of the minifiers.
Benchmarks last updated on Apr 23, 2023.

- 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 20 second timeout
- Artifact integrity is verified by a test before and after minification
- Minifier upgrade PRs are automated via WhiteSource Renovate
- Benchmarks are gathered on every PR via GitHub Actions (verifiable minified artifacts are uploaded on each run)
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.
