SVG Minifiers Compared — SVGO, svgcleaner & Online Tools
Minifying SVG reduces file size for faster web delivery. Compare SVGO, svgcleaner, and online minifiers on compression quality and ease of use.
SVGO vs svgcleaner
SVGO is Node.js-based and the most widely adopted tool in the JavaScript ecosystem. svgcleaner is a Rust-based alternative focused on safe optimization — it avoids changes that could alter visual appearance. svgcleaner is more conservative but less likely to break complex SVGs.
- SVGO: most aggressive optimization, 20+ plugins, JS ecosystem
- svgcleaner: Rust-based, safer defaults, desktop GUI available
- SVGO + --multipass typically achieves better compression than svgcleaner
Online SVG Minifiers
svgomg.net is the best browser-based SVG minifier — it's a GUI for SVGO with plugin toggles and live preview. SVGminify.com and other online tools use SVGO or similar engines. For one-off minification: use svgomg.net. For build pipelines: integrate SVGO via npm.
- svgomg.net: best online GUI for SVGO, free, no signup
- SVGminify.com: simple paste-and-minify interface
- Build pipeline: vite-plugin-svgo, rollup-plugin-svgo, imagemin-svgo
Frequently Asked Questions
What is the maximum SVG compression I can achieve?
With SVGO --multipass followed by gzip or Brotli HTTP compression, you can achieve 85–95% total size reduction on complex SVGs. The SVG file itself typically reduces 30–60% with SVGO; HTTP compression adds another 50–70% on the wire.
Can SVG minification break my SVG?
Aggressive SVGO plugins can occasionally alter visual appearance — particularly path precision reduction and viewBox cleanup. Always test minified SVG visually before deploying. Use SVGO's preset-safe-or-similar presets for production pipelines.
