Benchmarks last updated on Sep 24, 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 drop like flies and milliseconds scream. This field was tight, weird, and deliciously tactical. Some tools came to grind out the smallest possible download. Some came to sprint. A few tried to do both and actually pulled it off.
@swc/core — the all-round bruiser takes the crown. It didn’t always win the headline sprint, but it won the heavy fights that matter most. It delivered top-tier gzip sizes on several of the largest artifacts (echarts, antd, three) while keeping times in the hundreds of milliseconds rather than seconds. That combination of near-best compression on big bundles and sensible speed makes it the most practical champion for real-world transfer-cost wins. This wasn’t a runaway; it was a hard-fought decision driven by dominance on the heavyweights where bytes saved are worth more.
- uglify-js — the Compression King. Most wins by count and brutal at shaving bytes on many packages, especially small-to-mid ones. The trade-off is time: it’s often orders of magnitude slower on big bundles. Pick it if absolute smallest gzip is the single non-negotiable metric.
- oxc-minify — the Giant-Slayer. Took the biggest prize (TypeScript, the largest artifact) and produced excellent balanced results on other large bundles. Fast and compact where it counts.
- @cminify/cminify-linux-x64 — the Speed Demon. Repeatedly the fastest, especially on very large files, but at a clear cost in gzip size. Ideal for rapid CI loops or dev-time fast paths where build time beats the last percent of compression.
- @tdewolff/minify — the Micro-Sprinter. Insanely fast on small packages and offering solid compression there. A great pick for tiny assets or ultra-low-latency toolchains.
- terser — showed up with a notable victory (jquery) and remains a strong, focused performer when it nails a target.
- @swc/core deserves a second nod for consistency: frequently the "most balanced" choice across rounds.
- babel-minify — failed while processing "d3": "unknown file: Cannot read properties of undefined (reading 'add')"
- tedivm/jshrink — failed while processing "d3": "RuntimeException: Unclosed regex pattern at position: 289075 in /packages/minifiers/vendor/tedivm/jshrink/src/JShrink/Minifier.php:660"
This race was won by balance, not bravado. If your priority is raw smallest transfer size and you can tolerate slow minification, uglify-js is merciless. If you want strong compression on the big bundles without waiting an age, @swc/core is the practical champion. If build-time is your enemy, reach for @cminify or @tdewolff. Remember: these results measure only gzipped size and speed. Real-world choices also hinge on developer experience, ecosystem fit, and correctness guarantees—things this scoreboard didn’t measure. Pick the tool that matches your pipeline’s real constraint: transfer cost, CI latency, or pure byte-surgery.

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.>
