SVGO vs picosvg
SVGO optimizes SVG while preserving its structure, whereas picosvg flattens SVG into a deliberately restricted simple subset.
Optimization vs Structural Flattening
SVGO reduces file size while keeping an SVG's groups, transforms, and structure intact and editable, whereas picosvg deliberately destroys that structure, resolving every transform and group into flat absolute paths for tools that can't handle the full SVG specification.
- SVGO reduces size while keeping groups, transforms, and structure intact
- picosvg resolves every transform and group into flat absolute paths
- picosvg deliberately destroys structure that SVGO carefully preserves
When Flattening Is Actually Required
Flattening becomes necessary when feeding SVG into font compilers or icon toolchains that only support a restricted subset without transforms or nesting, situations where SVGO's structure-preserving optimization alone wouldn't make the file acceptable to those tools.
- Font compilers and icon toolchains often support only a restricted subset
- Those tools reject transforms and nested groups that SVGO preserves
- picosvg makes such files acceptable where SVGO alone would not
Frequently Asked Questions
Should I run picosvg on regular web SVGs?
Usually not — flattening removes structure without web benefit, so SVGO alone is the right choice unless a downstream tool specifically requires a flattened subset.
Can I run both SVGO and picosvg on the same file?
Yes, a common sequence flattens with picosvg to satisfy a downstream tool's constraints, then optimizes the flattened result with SVGO for size.
