Benchmarks last updated on Nov 8, 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 fall like confetti and milliseconds matter. The field was stacked: old-school grinders, nimble newcomers, and a couple of exotic entries. The scoreboard told a story of raw size, lightning speed, and clever middle-grounders. Let’s call the race.
Champion: @swc/core. It didn’t always have the single smallest number, but it won where it counts—big files and practical trade-offs. @swc/core grabbed top gzip spots on several large artifacts (vue, three, echarts, antd) and kept times in the hundreds of milliseconds when rivals crawled into seconds. When uglify-js shaved a hair more off compression, it often cost many seconds on the clock. Example: on d3 uglify produced 87.02 KB but took ~4s; @swc delivered 87.22 KB in 145 ms. On victory uglify’s tiniest edge (157.44 KB) came at 6.6s versus @swc’s near-identical 157.75 KB in 287 ms. For real-world workflows where transfer size matters but CI and developer feedback loops also do, @swc/core strikes the best balance across the board.
- uglify-js — The size champion for many rounds. It produced the smallest gzips most often, especially on small-to-mid libs. Expect excellent compression at the cost of noticeably slower runs on large bundles.
- oxc-minify — The surprise powerhouse. Wins on the largest single artifact (typescript) and the terser package, with very competitive sizes and a consistently snappy middle-ground speed.
- @tdewolff/minify — Blindingly fast. When milliseconds matter (dev servers, CI hot paths), it often finishes first with compression only a percent or two behind the best.
- @cminify/cminify-linux-x64 — The turbo sprinter. It repeatedly finished fastest on very large inputs, trading off some compression for raw throughput. Great when speed beats every byte.
- terser — Reliable on mid-size code. Took the best spot on jquery and stayed competitive otherwise.
A quiet note: several tools in the lineup (bun, esbuild, google-closure-compiler, @swc/core’s peers) showed solid runs but didn’t dominate the metrics shown here. They may still be attractive for other reasons not measured in this race.
- babel-minify — Failed on "d3" during minification: "unknown file: Cannot read properties of undefined (reading 'add')"
- tedivm/jshrink — Failed on "d3" during minification: "RuntimeException: Unclosed regex pattern at position: 289075 in /packages/minifiers/vendor/tedivm/jshrink/src/JShrink/Minifier.php:660"
This championship was strictly about two things: gzipped size and minification speed. Real-world choices also hinge on developer experience, ecosystem, compatibility, and feature needs—none of which we scored here. If you ship to users and care most about bytes on the wire, pick the tool that wins your target-artifact class. If you iterate fast and run minification in hot CI, favor the blindingly fast options that keep the pipeline humming. And if you want a pragmatic all-rounder for big apps, @swc/core proved it can win the marquee rounds without making you wait.

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.>
