Benchmarks last updated on Sep 15, 2025.
- 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 are the prize and milliseconds are the applause. The field was a mix of old pros and hungry newcomers. Some sliced greedily for every last byte. Others sprinted like sprinters afraid of CI timeouts. The outcomes were dramatic, and the trade-offs were delicious.
Uglify‑JS takes the crown. It grabbed the smallest gzipped outputs most often, winning five rounds including React, Moment, Lodash, D3, and Victory. When absolute transfer size mattered, uglify‑js was the one shaving deepest. The caveat is speed: uglify‑js can be noticeably slower on bigger artifacts (seconds where others finish in tens or hundreds of milliseconds), so it’s the heavyweight champion—brutal on bytes, patient on clocks.
@swc/core was the most consistent all‑rounder. It produced near‑best gzips in many rounds, and did so far faster than uglify‑js on medium and large bundles. If you want tiny transfers without paying the full time penalty, swc is the pragmatic choice.
oxc‑minify shone on the very largest artifacts. It edged out others on TypeScript and the terser package and kept times sensible—excellent when the file sizes climb and you still care about both metrics.
@tdewolff/minify was the speed demon of the small and medium races. It often finished in single‑digit milliseconds with compression only a hair behind the winners—great for CI or rapid iteration where time matters more than a percent of gzip.
@cminify/cminify-linux-x64 deserves a shout for raw velocity on the big files. It was the fastest on several large inputs but traded away significant compression—perfect for fast feedback loops, not for shaving final payloads.
Terser earned a trophy for best on jQuery—still a specialist that can win when the shape of the code fits its strengths.
- babel‑minify — failed on "d3": "Cannot read properties of undefined (reading 'add')".
- tedivm/jshrink — failed on "d3": "Unclosed regex pattern..." runtime exception.
If your priority is smallest transfer size, pick uglify‑js and be ready to budget CPU time. If you want the best practical balance—good gzip and much faster runs—@swc/core is the safest bet. If you minify huge bundles and want both speed and very small payloads, oxc‑minify is a rising star. If your pipeline needs near‑instant minification, @tdewolff/minify or cminify will buy you time at the cost of a few kilobytes. Remember: these results measure only gzip size and speed. Developer experience, compatibility, and correctness are also real factors you’ll want to test in your own stack. Choose the tool that matches whether you’re fighting bytes on the wire or fighting build minutes in CI.

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

<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.>
