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 27, 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 JavaScript minifiers has been intense! We've seen jaw-dropping speed, mind-boggling compression ratios, and a few casualties along the way. Let’s recap the highlights and crown the winners of this electrifying showdown!

Best minifier

Drumroll, please... @swc/core storms ahead to claim the crown! Across a variety of scenarios, it consistently delivered stellar compression ratios while maintaining lightning-fast speeds. It dazzled us with a blistering 14 ms on React, aced the massive ECharts and Antd benchmarks with robust compression, and emerged unscathed from the heavyweight TypeScript match at just 859.20 kB. While not always the fastest, @swc/core strikes a winning balance between size and speed. For the average user who values a high-performance, no-fuss solution, this is the one to beat!

Honorable mentions

Uglify-js: The precision and sheer compression power of Uglify-js were stunning, with top-notch results in almost every round—including being the reigning champion on Moment.js and lodash! However, its performance dropped off drastically as file size grew, with timeout issues in extreme benchmarks.
Terser: Packing a punch with robust compression and high effectiveness, Terser came in near the top on many rounds. While it offers powerful capabilities, it struggled with processing speed as sizes grew, timing out on larger files.
@tdewolff/minify: The speed demon of this competition! For users who prioritize blindingly fast minification speeds and can live with slightly less aggressive compression, this is an excellent choice. It breezed through every round with sub-200ms times, proving its worth for continuous build systems.
OXC-minify: A dark horse in the race that prioritized rapidity while rarely sacrificing too much compression. It even topped the massive “terser” package, making a strong case for itself.

Eliminated

Babel-minify: Stumbled on the “d3” package with fatal errors. A promising contender, but its inability to handle certain ES patterns makes it unreliable for production-grade builds.
Tedivm/jshrink: Couldn’t finish the race due to Regex challenges during “d3,” showing its limitations with complex libraries.
Bun: While speedy, it failed in post-validation (TypeScript), outputting incorrect results. A cautionary tale: correctness matters as much as speed and compression.

Quick outro

What a thrilling face-off! Every contender showed their strengths, and @swc/core emerged as a well-rounded champion with outstanding results. Uglify-js and Terser proved their compression prowess in tougher terrains, while @tdewolff/minify stole the show with its breakneck speeds. Hats off to these tools for pushing boundaries—now go build something awesome with your newfound minification champion!
