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 17, 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

Welcome to the JavaScript Minification Grand Prix! We’ve seen jaws drop and algorithms flex their muscles. Let’s dive into the results from this exhilarating showdown.

Best minifier

🏆 @swc/core is our top recommendation! With an unbeatable combination of razor-sharp compression percentages and blazing fast speeds on larger files, it consistently slices through megabytes like butter. From shrinking antd by 55% in just over a second to reducing typescript by 46% in under 2 seconds, it’s a weapon of choice for developers wanting balance without compromise. It’s your one-size-fits-all minifier champion.

Honorable mentions

Uglify-js: A master of precision and size reduction, it topped tests for raw compression, such as cutting lodash to 26% or trimming d3 to 67%. But alas, its slow speeds (3+ seconds for mid-sized libraries!) make it optimal only for tasks requiring extreme slimming but not speed-sensitive workflows.
@tdewolff/minify: This speed demon consistently finishes first, shredding packages in milliseconds (e.g., 7 ms for moment, 13 ms for vue). However, its compression tends to lag slightly (see d3, antd, and three), so it’s best when rapid output is key.
oxc-minify: A rising star, often just milliseconds behind @tdewolff/minify while delivering comparable results. It held its ground against typescript and clinched first place in terser’s own compression race. Reliable and potent for speed-critical pipelines.
Terser: A veteran, terser shines for code compatibility in complex setups. It nearly matches uglify-js in compression but edges slightly ahead in speed while staying reliable, especially under “no compress” conditions.
Esbuild: While not the strongest compressor (results sit firmly in the 48–59% range), it’s a rocket in performance (mere seconds!). Use this when you need files quickly and compression is a bonus.

Eliminated

Babel-minify: A stumble at the starting line – breaking on d3 with a puzzling Cannot read properties error. A no-go; heavy lifting’s not its forte.
Tedivm/jshrink: Regex trouble mid-race! Unclosed patterns caused d3 to crash hard, proving it’s not reliable for larger, complex inputs.
Bun: A promising contender let down by post-validation issues during typescript handling. Breaks even when files appear correct; proceed with extreme caution.

What a race! Congratulations to our winners and challengers alike for pushing the boundaries of minification. For the average user, @swc/core is the clear victor, striking a balance between size savings and speed, with @tdewolff/minify leading the charge when time-to-output is critical. Until next time, keep those files slim and swift!
