google-closure-compiler	20250520.0.0	2025-05-22
bun	1.2.14	2025-05-21
@swc/core	1.11.29	2025-05-21
@tdewolff/minify	2.23.8	2025-05-21
oxc-minify	0.71.0	2025-05-20
terser	5.39.2	2025-05-15
esbuild	0.25.4	2025-05-06
uglify-js	3.19.3	2024-08-29
babel-minify	0.5.2	2022-05-06
tedivm/jshrink	1.7.0

Benchmarks last updated on May 22, 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

Ladies and gentlemen, hold on to your hats because the battle of JavaScript minifiers has come to a dramatic conclusion! We've seen jaw-dropping compression ratios, blistering performance, and a few stumbles along the way. Let’s dive into the glittering results and crown the ultimate champion!

Best minifier

🏆 Top Recommendation: @swc/core
This bad boy stole the show with its stellar balance of compression and blazing speed. It consistently delivered the tiniest Gzip sizes—often competing neck-and-neck with veterans like UglifyJS—while leaving its competitors in the dust with lightning-fast processing. In the gargantuan "antd" test, @swc/core shrank a whopping 825.18 kB down to just 452.48 kB (55%) in just 858 ms. And in the massive "typescript" showdown, it obliterated the competition, finishing in 1,745 ms with an incredible size reduction. It's the go-to minifier for users who need exceptional results without wasting precious time.

Honorable mentions

oxc-minify
Talk about a rising star! This newcomer was cutting-edge fast, often finishing within 12–35 ms for smaller packages. It maintained respectable gzip sizes, especially in the "terser" test with its chart-topping 122.35 kB (63%). If speed is your game and you're willing to sacrifice a fraction of compression, oxc-minify is an amazing choice.
@tdewolff/minify
This speed demon minifies files faster than you can blink. It’s the reigning champion of raw speed, wrapping up tasks like "lodash" in a blistering 12 ms and "antd" in just 141 ms! The tradeoff? Compression is often 1–3% worse compared to @swc/core or UglifyJS. Still, for time-crunched users, it’s a spectacular contender.
UglifyJS
A classic that’s aging like fine wine. While lagging behind with its processing times, UglifyJS consistently achieved some of the smallest gzip sizes. Take "d3," where it smashed the input size of 130.69 kB down to just 87.02 kB (67%). It’s slower but reliable, making it a favorite for those prioritizing compression over speed.
Terser
This modern favorite performs solidly in compression (e.g., "antd" at 457.79 kB) and is significantly faster than UglifyJS. However, its processing times, especially on giant packages like "echarts" and "antd," could leave you drumming your fingers. A balanced option if time isn't your main concern.

Eliminated

Babel-Minify
Babel-Minify tapped out early with an error that left "d3" dead in the water. Its shrinking prowess showed promise before this mishap, but its reliability leaves much to be desired.
tedivm/jshrink
The regex pattern woes were its undoing, failing the same "d3" package as Babel-Minify. Unfortunately, the tools of its trade need some fine-tuning before re-entering the race.
Bun
What started strong ended with heartbreak as Bun stumbled on the "typescript" package due to validation mismatches. Consistency issues make it unsuitable for production pipelines as of now.

The Final Word

What a showdown! Every minifier brought something special to the table, but @swc/core clinched the title as the ultimate all-rounder. For those in a rush, @tdewolff/minify and oxc-minify will turbocharge your workflow, while UglifyJS and Terser remain solid picks for size-first enthusiasts.

Kudos to all the contenders—you pulled off some truly impressive results under the pressure!
