Benchmarks last updated on Jul 31, 2025.

🙋‍♂️ 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
Each minifier is minimally configured (sourcemaps & comments disabled), comparing out-of-the-box experience
Minifier upgrade PRs are automated via WhiteSource Renovate
Benchmarks are updated on every PR via GitHub Actions
The raw benchmark data is available in /packages/data/data/data.json

⏱ 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.

⚔️ Minifier showdown

Note

🤖 This analysis is AI generated

The JavaScript minification showdown is over, and what a race it's been! With file sizes slashed and speeds pushed to the limit, there's a clear sense of who the champions are. Let’s break it all down!

Best Minifier

@swc/core takes the crown as the top overall minifier! It combines consistently small gzip sizes with blazing speed, making it the best option for most developers. Across twelve rounds, @swc/core delivered stellar compression with a performance edge that feels designed for real-world usages. It excelled in reducing weights for heavyweight packages like antd and typescript while managing to stay lightning fast. Balancing efficiency and speed has never looked this smooth!

Honorable Mentions

1. oxc-minify
The dark horse of the competition! It doesn't always have the smallest sizes but is jaw-droppingly fast, often reaching sub-50ms on mid-sized and even large libraries. If speed is your top concern and you're okay sacrificing a couple of bytes, oxc-minify is stellar.

2. uglify-js
The veteran still proves its dominance with minimum file sizes, most notably a jaw-dropping 26% reduction on lodash. It’s perfect for surgical minification where every byte counts, though its slower speeds often left it lagging behind.

3. @tdewolff/minify
The fastest minifier over the first half of the rounds! It regularly clocked in at 3-13ms for smaller files. However, its compression gains dropped off on larger libraries, making it better for smaller or time-critical tasks.

4. terser
While not the fastest or smallest, terser did admirably in maintaining a consistent balance of compression and speed, making it a solid middle-of-the-road contender if you're juggling mixed sizes.

Eliminated

1. babel-minify
We wanted to love babel-minify, but it tripped and fell out of the race early. Failing round 6 (d3) due to a mysterious property access issue, it couldn't recover.

2. tedivm/jshrink
This minifier crashed spectacularly during the regex-heavy d3 minification, reminding us why regex parsers need extra love. Proceed with caution.

3. bun
Oh, Bun... So much promise, but a validation mismatch ruined its bid during round 12 (typescript). It just needs some rounding off to be ready for prime time.

Conclusion

What an impressive performance by all our participants! Special congrats to @swc/core, the reigning champion for balancing lightning-fast speeds with industry-leading compression. If you crave speed alone, @tdewolff/minify and oxc-minify are worth reaching for. For byte-perfect precision, uglify-js is still the sharpest tool in the shed.

Stay tuned for the next competition—there’s always room for improvement in the quest to shrink!
