Benchmarks last updated on Nov 27, 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 every kilobyte is a trophy and every millisecond is a bragging right. The field was ruthless, the upsets delightful, and the final lap came down to who could shave bytes without turning the clock into a traffic jam.
@swc/core takes the crown. It wasn’t always the absolute tiniest on every single package, but it won the hard rounds: multiple best-compression finishes on large, real-world bundles (vue, three, echarts, antd) and showed steady, sensible speed. That combination of top-tier compression on hefty artifacts and consistently respectable runtimes makes @swc/core the practical champion for teams who care most about transfer size but still need builds that don’t stall CI.
Why not uglify-js? Uglify is the raw compression bruiser — five rounds with the smallest gzips, and it squeezes mid-sized libraries to impressive lows. But those savings often came at a cost in time. When the input grew, uglify’s runtimes ballooned (thousands of ms on the largest bundles), which makes it a bruising pick for CI-heavy workflows. It’s an excellent option if you absolutely must minimize bytes and can tolerate slower minification.
oxc-minify is the clever silver lining. It grabbed the biggest single prize — the mammoth TypeScript bundle — and showed top-tier balance on large files with much friendlier runtimes than the slowest competitors. If you want near-best size plus much better iteration speed than traditional heavyweights, oxc earns a hard nod.
- @cminify/cminify-linux-x64 — the speed demon. Repeatedly near-instant (tens of ms) but with clearly weaker compression on larger assets. Perfect for rapid local workflows or where minifier latency must be negligible.
- @tdewolff/minify — blink-and-it’s-done for small-to-medium files. Slightly bigger outputs than the champions, but absurdly fast. Great for dev servers and tiny CI steps.
- terser — the best on jquery and a solid performer overall. A reliable tool when you want a modern successor to uglify’s style.
- uglify-js — the “bring-a-sledgehammer” compressor. Best compression count, but costly time on big targets.
- babel-minify — crashed on d3 with "Cannot read properties of undefined (reading 'add')". Removed from contention.
- tedivm/jshrink — failed on d3 with "Unclosed regex pattern" runtime exception. Removed from contention.
This race only judged gzip sizes and minification speed. Real-world choices also hinge on correctness, compatibility, developer experience, install footprint, and integration pain — none of which were measured here. If your pipeline values absolute smallest transfer size and you can afford longer minification, uglify-js is tempting. If you want the best practical mix of tiny payloads and reasonable CI times across the biggest bundles, @swc/core is the pick. If you need near-instant results and can trade a chunk of compression for speed, @cminify or @tdewolff/minify are compelling.
It was a tight, entertaining Grand Prix. Pick the tool that matches your pit crew’s priorities, and may your bytes be few and your builds be swift.

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.>
