Benchmarks last updated on Mar 2, 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 are pitted against milliseconds and every saved kilobyte gets a cheer. The field mixed old reliables with hungry upstarts. The races were tight on tiny libraries and ruthless on the huge bundles. Now for the podium.
@swc/core takes the crown. It found the sweet spot between razor‑thin gzipped output and real speed. It claimed best compression on several big, brutal targets (three, echarts, antd) while staying fast enough to be practical. When uglify or oxc skimmed off a hair more of the final byte, @swc/core was usually within a percent and an order of magnitude quicker. That combination—top‑tier compression on large artifacts plus snappy runtimes—wins the overall race by delivering the transfer savings that matter without killing your pipeline.
uglify-js — The old size king. It squeezed the smallest gzips in many rounds (react, moment, lodash, d3, victory). The catch: those tiny gains often came with much higher minify times. If absolute smallest transfer size is your single metric and you can afford the wait, uglify still scores. oxc-minify — The speed demon and big‑file performer. Lightning fast on many inputs and outright best on the largest test (typescript). It frequently hit near‑best sizes while running in a sliver of the time the slow compressors used. @cminify/cminify-linux-x64 — Consistently the quickest on the largest bundles, but it pays for that speed with noticeably worse final gzips. Great when latency matters more than last bytes. @tdewolff/minify & terser — Quietly useful. @tdewolff/minify turned in competitive times and respectable sizes on big files. Terser still shines on some mid‑sized inputs (jquery) with a good balance of size and speed.
- babel-minify — Crashed on "d3": Cannot read properties of undefined (reading 'add').
- tedivm/jshrink — Crashed on "d3": Unclosed regex pattern runtime error.
This leaderboard speaks only in gzips and milliseconds. Choose by trade‑offs: pick uglify-js when the last byte dominates your cost model, pick @swc/core when you want excellent compression without grinding your CI, or pick oxc‑minify/@cminify when speed is the practical priority. Real‑world decisions also factor in API, compatibility, and correctness—things these benchmarks didn’t measure—so try the top candidates in your own stack before locking them in. The race was fierce, and the tiny margins changed everything.

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.>
