Benchmarks last updated on Feb 23, 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 every kilobyte is a trophy and every millisecond is a slipstream. The field mixed old-school grinders and sprinters built for CI. Some tools went for glory and shaved every byte they could. Others sprinted so fast you barely saw the output. The story is all about trade-offs, and the lead swapped lanes more than once.
@swc/core takes the crown. It was the most convincing all-rounder — consistently at or very near the smallest gzip sizes, while staying orders of magnitude faster than the absolute byte-chasers. On small toys like react it matched the best size (8.19 KB vs uglify’s 8.18 KB) but finished in 12 ms versus 511 ms. On heavyweights it often owned the podium: echarts (321.08 KB, 594 ms) and antd (452.46 KB, 728 ms) were won by swc outright, and three/three-ish targets saw swc deliver the best balance of tiny bytes and practical speed. In plain terms: swc gives you near-best transfer sizes without crippling build times, which is exactly the kind of balance that matters in real builds.
- uglify-js — The razor. Most smallest-gzip victories across the series (react, moment, lodash, d3, victory). If raw bytes are your single-minded KPI and you can tolerate long runs (times often in the seconds), uglify will earn you the last 1–3% of compression. It pays a big time penalty for that thrift.
- oxc-minify — The sprinter with endurance. Extremely fast in almost every run and it pulled the biggest upset by winning the largest test (typescript, 853.12 KB in 607 ms). It’s a superb choice when you want very small output on huge artifacts without waiting forever.
- @cminify/cminify-linux-x64 — The blink-and-it’s-done specialist. Repeatedly the fastest, especially on big files, but it trades off compression depth. Great for fast CI where milliseconds matter more than shaving a few KB.
- @tdewolff/minify — A steady fast finisher. Frequently among the fastest and consistently close on size for medium-to-large bundles. Good compromise when you need speed and decent compression.
- terser — Reliable and competitive in several mid-sized cases (notably jquery). Slower than the new generation, but still produces good sizes.
- babel-minify — Crashed on d3 during minification: "Cannot read properties of undefined (reading 'add')". Removed from contention for stability reasons.
- tedivm/jshrink — Crashed on d3 with a runtime exception parsing a regex. Removed for failing to complete the benchmark.
This race measured two things only: gzipped bytes and how long the minifier took to get them. Real-world choices also care about correctness, compatibility, developer experience, install size, APIs and ecosystem. If you want the absolute smallest delivery and can afford slow runs, uglify-js still delivers. If you want tiny bytes and a tool that behaves at CI speed, @swc/core is the pragmatic champion. If you need blistering throughput and are willing to accept larger output, reach for @cminify or @tdewolff. And if you have monster bundles (hello, TypeScript), oxc-minify proved it can both shrink and sprint.
Pick the tool that wins for your workflow: the fanciest trophy isn’t always the one you can carry home every day.

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.

<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.>
