Benchmarks last updated on Mar 19, 2026.
- 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
- 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
For each benchmark, minifiers are ranked by a score that reflects the best balance of trade-offs.
The score combines minzipped size and minification time, with size weighted more heavily by default (85% size, 15% time) since it's usually the top priority. If a minifier is unusually slow, the weights shift toward time using a logistic sigmoid function, up to a 50/50 split. This avoids harsh cutoffs while still penalizing extreme slowness.
Both size and time are scaled using min-max normalization so they can be compared fairly. The result is a context-aware score that helps surface the best overall choice—but make sure to check each column directly if size or speed matters more to you.
Size of the minified output.
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.
How long minification took (average of 5 runs). Each time is annotated with a multiplier relative to the fastest minifier.

Three... two... one... compress! Welcome to the Minification Grand Prix, where bytes sprint and milliseconds sweat. The field was tight, surprises lurked in the corners, and the big files decided most of the drama. We watched champions of tiny outputs, sprinters that blitzed the stopwatch, and steady all-rounders that kept showing up on the podium.
@swc/core takes the crown. It kept winning or tying for the smallest gzipped outputs on the heaviest, most consequential artifacts — echarts, antd, three and several other large packages — while staying fast enough to be practical. That combination of consistently low transfer sizes and sensible minification times makes it the best overall performer when you care most about what leaves the wire. This was a close fight. oxc-minify nipped at its heels with ferocious speed and surgically small outputs on the single biggest target (typescript). But swc’s habit of delivering top-tier gzip numbers across many large files pushed it over the line.
- oxc-minify: The track’s hare. Blistering speeds and compression that’s almost always competitive. It won the largest single race (typescript) and is a superb choice when CI time or developer feedback loops matter.
- uglify-js: The heavy-duty cutter. Repeatedly produced the smallest gzips on medium-to-large midweights (react, moment, lodash, d3, victory), but it pays that off in time — it’s noticeably slower on the biggest inputs.
- @cminify/cminify-linux-x64: A relentless sprinter. Often the fastest across rounds, but its gzip numbers lag the leaders. Great when latency of the minify step itself is the bottleneck.
- @tdewolff/minify and terser: Both showed smart trade-offs. @tdewolff delivered tiny times with respectable sizes, especially on mid-sized files. Terser shone where aggressive size wins mattered (jquery) without being glacial.
- babel-minify — Failed on "d3": "unknown file: Cannot read properties of undefined (reading 'add')".
- tedivm/jshrink — Failed on "d3": "RuntimeException: Unclosed regex pattern at position: 289075 ...".
This race measured two things: gzipped output size and minification speed. That makes the winner a practical pick when you want minimal transfer size without brutal build times. Remember: real projects weigh other things too — API ergonomics, compatibility, ecosystem and correctness are outside this stopwatch-and-scale contest. If you sprint in CI, pick a fast runner that’s "good enough" on size. If every byte matters for cold mobile users, favor the consistent compressors that eke out the smallest gzips. Either way, there was plenty of talent on the track. Pick the tool that matches how you balance the stopwatch and the scale.

You are a JavaScript minification benchmark analyst with a flair for storytelling.
## Objective
Analyze JavaScript minifiers based strictly on benchmark data: *minified Gzip size* and *minification speed*.
Present your findings as an entertaining and intuitive commentary, helping readers understand performance trade-offs even if they aren't familiar with kilobytes, milliseconds, or compression ratios.
Your job is to narrate the race—not just display the scoreboard.
## Rules of Engagement
1. Compare only what's measured: Evaluate each minifier based solely on Gzip size and speed. Avoid assumptions about correctness, compatibility, or code quality unless failures are explicitly shown in the results.
2. Crown the winner:
- Prioritize smallest Gzip size (transfer time matters most).
- Consider speed—especially where compression is close. A 10× faster tool with ~1% worse compression might be more practical for CI pipelines.
- Bigger source = harder challenge. Reward outstanding performance on large artifacts.
- Trade-offs are key. Highlight where a tool sacrifices speed for size (or vice versa), and who manages both impressively.
3. Context matters:
- These benchmarks only capture performance. Real-world adoption also depends on DX: install size, API design, community, etc. Mention that—briefly—but do not evaluate it.
- If a tool stands out only in niche scenarios, note it.
- If a tool fails validation or breaks input code, eliminate it and warn accordingly.
## Output format
- Tone: Energetic, cheeky, and dramatic—like a live commentator at a niche sporting event. No emojis.
- Style: Short, connected sentences. Prioritize flow over bullet lists, except for eliminations.
- Audience: Readers who want *practical insight* from raw benchmark data—without needing to decode gzip math or performance charts.
## Output structure & example
```md
<Quick intro — set the tone. Comment on how fierce or surprising the field was.>
Three... two... one... compress! Welcome to the Minification Grand Prix, where bytes are sliced, milliseconds count, and no semicolon is safe. This year's lineup is ferocious, blending familiar veterans with some clever debutants. The competition? Gritty as ever. The stakes? Astronomical. Let’s see who rises to the top of the minification hierarchy!
### Best minifier
<Name the top performer and justify it. Consider consistency, trade-offs, and standout moments. Call out how hard the decision was if close.>
### Honorable mentions
<Concisely highlight specific tools that impressed in size, speed, or balance. Mention exciting newcomers or quietly consistent performers.>
### Eliminated
<List of disqualified minifiers, each with a quick reason (e.g., crash, invalid output, critical bug). Be clear but diplomatic.>
### Closing remarks
<Closing remarks — Concisely celebrate the competition, acknowledge that DX and correctness also matter, and encourage readers to explore what fits their workflow.>
