## 🙋♂️ Why?
1. To help you pick a minifier that fits your needs
2. To promote JS minifiers and document their performances
3. 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](https://www.whitesourcesoftware.com/free-developer-tools/renovate/)
- Benchmarks are updated on every PR via [GitHub Actions](https://github.com/privatenumber/minification-benchmarks/actions/workflows/benchmark.yml)
- The raw benchmark data is available in [`/packages/data/data/data.json`](/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](https://en.wikipedia.org/wiki/Gzip).
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.

> [!NOTE]
> 🤖 This analysis is AI generatedWoah, what a race! It’s been an electric showdown between the heavy hitters in the realm of JavaScript minifiers. With compression rates and processing speeds on the line, it's time to crown the victor and analyze the knockouts. Without further ado, let’s dive into the results.
### Best minifier
💥 **@swc/core** takes the crown for the average user! Balancing impeccable compression ratios and breathtaking speed, SWC repeatedly came out near the top. While it didn’t win every round, its performance was dazzling, especially for larger files like `antd` and `typescript`. For instance, it flattened the enormous 1.88 MB `typescript` package to 859.20 kB (46%) in just 2,177 ms, a brilliant feat. This suggests SWC consistently delivers fantastic results with both small and massive files. It’s the minifier to bet on for those looking for reliable compression and swift execution.### Honorable mentions
- **Ugly-yet-effective Production Workhorse: uglify-js**
Despite its cranky processing times that bordered on a timeout in some rounds (hello, `antd`!), uglify-js was an absolute champion at squeezing the smallest possible size for multiple files. Take the `lodash` package: 24.69 kB (26%) in 1,689 ms—a clear finish over the competition. For those willing to trade time for size dedication, uglify-js is your faithful servant.- **Young and Speedy: oxc-minify**
Coming in hot, oxc-minify performed blisteringly fast in nearly every round while keeping size reductions respectable. It sped through `lodash` in 12 ms and `terser` in 38 ms but without quite achieving the size reductions of uglify or SWC. Nonetheless, it's the sprinter of this competition, excelling at zipping through your code with fantastic efficiency.- **Tactical Leader: @tdewolff/minify**
If raw speed is your only metric, @tdewolff/minify will dazzle you! For example, it demolished `three` in just 51 ms (though it was a bit chunkier at 164.61 kB compared to SWC’s 158.76 kB). Super-slick for real-time pipelines where execution time takes precedence over file size.- **esbuild**
A solid performer among the compact-size group, esbuild offers speedy reductions but doesn’t punch the same weight as top-notch minifiers above. However, with its simple API and competitive processing of smaller packages, it's worth considering for light workloads.### Eliminated
- **babel-minify**: Unfortunately, this minifier tripped on `d3` due to a runtime error, thus crashing out of our competition. Proceed with caution—its development seems stagnant compared to its competitors. Not for the faint of heart!- **tedivm/jshrink**: Ouch! An unclosed regex pattern on `d3` made this minifier wave the white flag. While not necessarily a lightweight entrant, reliability issues keep it from competing seriously.
- **bun**: This up-and-comer couldn’t hold up to the rigors of JS minification, failing the post-validation stage on `typescript`. Definitely unstable for production use right now.
### Quick outro
Wow, what an exhilarating display of compression power and speed finesse! While @swc/core emerges as the undeniable superstar of this tournament with its consistent all-around performance, our honorable mentions prove that there's more than one path to minification glory. Huge respect to all participants for putting up an impressive fight—their efforts will leave JavaScript developers spoiled for choice. Stay tuned for the next championship!## Sponsors
