google-closure-compiler	20240317.0.0	2024-03-19
babel-minify	0.5.2	2022-05-06
tedivm/jshrink	1.7.0

Benchmarks last updated on Apr 9, 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 battle of the minifiers was nothing short of exhilarating! From blazing-fast speeds to compression wizardry, our contenders delivered impressive performances (most of them, anyway). Now, let's crown a winner, give credit where it's due, and call out some that didn’t cross the finish line.

Best minifier

@swc/core takes the crown! This powerhouse balanced lightning-fast speeds with top-tier compression consistently across packages large and small. Whether you're optimizing the compactness of libraries like react or stripping down huge monsters like typescript, @swc/core impressed with tiny Gzip sizes like 30.87 kB for jquery and 452.48 kB for antd—all while maintaining jaw-droppingly low processing times (as fast as 16 ms!).

If you're looking for a minifier that can shrink your JavaScript without breaking a sweat, @swc/core is your go-to. In short: it’s hard-working and incredibly fast!

Honorable mentions

oxc-minify dazzled us with blazing speeds (as low as 3 ms!) and respectable compression rates. It ruled when speed mattered most, making it ideal for time-sensitive workflows.
uglify-js remains the gold standard for compression, producing the smallest sizes consistently, such as 8.18 kB from react (awesome 42%). However, its sloth-like speed (up to 6,579 ms!) means it’s better for non-real-time use cases.
@tdewolff/minify deserves credit for being the fastest tool in many rounds, like minifying large files (antd in 141 ms!). While its compression wasn’t always stellar, it brought reliable speed at near-zero latency.

Eliminated

Alas, not everyone can rise to the occasion. Here’s who stumbled and why you should think twice before picking them:

babel-minify: Didn’t see the finish line; collapsed mid-race due to runtime errors on large files like d3.
tedivm/jshrink: Fumbled with regex patterns, leading to repeated failures. Ouch!
bun: Promised much but failed validation for differences in line endings (\n vs. \r\n). While speedy, no runner likes to hear "disqualified on a technicality."

Wrapping up

Bravo to all the contenders, especially those who pushed the boundaries! If you're an average user, pick @swc/core for stellar size-speed balance. For size-above-all enthusiasts, uglify-js will shrink until nothing’s left. And, if time is your bottleneck, oxc-minify or @tdewolff/minify has your back. What a race!
