@swc/core	1.11.29	2025-05-21
@tdewolff/minify	2.23.8	2025-05-21
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 28, 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

Hold onto your hats, everyone! We've just raced through an incredible showdown of JavaScript minifiers. From gzip size pyrotechnics to blazing-fast processing speeds, it’s a thrilling tale of victory margins and jaw-dropping defeats. Let’s dive into the highlights from this grueling, code-crunching arena!

Best Minifier

Drumroll... The title of Best Minifier goes to @swc/core! This overachiever has consistently achieved some of the smallest gzip sizes across various package sizes without breaking a sweat. It's also a speed demon. Take Round 6 ("d3"), where it crushed the race in only 156 ms while producing a stunning 87.21 kB output—just 0.19 kB behind the much slower uglify-js (3,927 ms). Whether it’s tiny utilities or hulking libraries like ECharts or TypeScript, @swc/core delivers both compression and speed with effortless grace. For the average user who wants great results with zero compromise, @swc/core is the one minifier to rule them all!

Honorable Mentions

Several minifiers put up heroic performances, and they deserve a standing ovation:

uglify-js – The master tactician of compression! For the absolute smallest gzip sizes, it reigned supreme in more than half of the rounds. Take Round 9 ("victory")—uglify-js stunned with a mere 157.44 kB output. However, with speeds often measured in seconds, it’s best suited for fire-and-forget build processes rather than quick iterations.
@tdewolff/minify – The reigning speed champion! Whether it was "lodash" (12 ms), "antd" (141 ms), or "d3" (32 ms), this minifier crushed times across the board. While its gzip sizes weren’t chart-toppers, they held their own respectably. Ideal for workflows prioritizing lightning-fast feedback.
oxc-minify – The rising star of balanced performance. Often finishing in the top four for both size and speed, this contender’s Round 7 triumph (122.35 kB in 36 ms for "terser") shows it’s ready to claim its seat at the grown-up table. A promising pick for power users.
terser – A reliable pick with strong gzip size compression and processing times that are respectable, though unspectacular. For those wanting a popular and widely-trusted minifier, terser won’t disappoint despite getting edged out by better performers.

Eliminated

Oh no! Some competitors didn’t make it to the finish. Diplomatic applause aside, here’s why you should steer clear of these next time:

babel-minify: Ran aground spectacularly on "d3" with an "undefined property" error. Not only did it flop mid-race, but the project hasn't seen updates in years.
tedivm/jshrink: With an "unclosed regex pattern" fiasco, JShrink tumbled during Round 6. It’s clear this one isn’t prepared for modern JavaScript complexities.
bun: Script-breaking issues in post-validation ("Expected values to be strictly equal") on "typescript" did away with its hopes. Bun’s ambitions are bold, but it’s not there yet.

What an electrifying showdown! Congratulations to all competitors for pushing the boundaries of what minifiers can do. @swc/core, hats off to you for holding your ground as the best all-rounder. For those seeking specialty tools, uglify-js, @tdewolff/minify, and oxc-minify have carved out their niches brilliantly. Here’s to more cutthroat competition and compressed code ahead!
