Minifier	Version	Release date ↓
bun	1.2.7	2025-03-27
@tdewolff/minify	2.22.4	2025-03-25
@swc/core	1.11.13	2025-03-24
oxc-minify	0.61.2	2025-03-23
esbuild	0.25.1	2025-03-10
terser	5.39.0	2025-02-13
uglify-js	3.19.3	2024-08-29
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 Mar 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

Ah, what a nail-biting contest this has been! The JavaScript minifiers lined up at the starting line, eagerly flexing their compression algorithms, and, boy, did they deliver some impressive performances! Let's break down the results and crown the ultimate champion of minification glory.

Best Minifier

@swc/core takes the grand prize with a breathtaking combination of compression efficacy and blazing speed. Across all the rounds, it consistently ranked among the top in terms of Gzip size with remarkable processing times. For instance, it utterly dominated in the "echarts" round by slicing the initial 684.61 kB file down to an outstanding 321.23 kB in just 793 ms—unreal performance! It's an all-around champ, reliable for both regular projects and heavier-duty applications like large libraries.

Honorable Mentions

uglify-js: A legendary name in the minification game! It delivered the absolute smallest Gzip sizes across many rounds. For example, in the "lodash" round, it achieved a staggering compression to 24.69 kB (26%), winning that round outright. However, the processing time can be unbearably slow—up to 6,579 ms in the "victory" challenge.
@tdewolff/minify: The Usain Bolt of minifiers! Frequently the fastest in many rounds (e.g., 2 ms in "react"), it's perfect when you need reasonable compression in record time. You're trading off a few extra Gzip bytes to save seconds, which might be exactly what you need in a fast build pipeline.
oxc-minify: Another sprinter in the minification race. It claimed several "fastest minifier" titles (e.g., "lodash" in 12 ms), and its Gzip sizes were impressively close to the leaders, such as @swc/core and uglify-js. Perfect for middle-ground use cases demanding both speed and solid Gzip savings.

Eliminated

babel-minify: Oh no! This one spectacularly crashed out of the "d3" round due to an internal error about "reading 'add.'" Not a safe choice for your production pipeline—it may just blow up mid-race.
tedivm/jshrink: Yikes! Regex handling issues caused it to stumble—got tripped up by an "unclosed regex pattern." If regexes are too complex, how will it handle your real-world JS code? Best avoid it.
bun: A promising newcomer, but alas, it got its logic tied up in post-validation problems while minifying "typescript." Code integrity is key; if the results are mismatched, it’s simply not reliable for now.

Closing Thoughts

Bravo to all the competitors! The race may have been tight, but @swc/core stood firm as our champion, offering a rare balance of tiny Gzip size and mind-blowing speed.

Yet, if you're looking for specific attributes, uglify-js is still king in raw compression, @tdewolff/minify outpaces everyone in pure speed, and oxc-minify is a solid all-rounder worth serious consideration.

So go ahead, pick the one that best fits your workflow, and let the minified bytes fly—happy coding!
