SVG Optimization Tools Compared — SVGO, Nano SVG & More
Compare every major SVG optimizer in 2024 — SVGO, Nano SVG, ImageOptim, Squoosh, and online tools — for compression quality, automation, and ease of use.
SVGO — The Industry Standard
SVGO is the most widely used SVG optimizer with the most plugin options. Used in build pipelines (webpack, Vite, Rollup), Squoosh, and most SVG tooling. The `--multipass` flag runs multiple optimization rounds for maximum size reduction.
- npx svgo --multipass file.svg
- 20+ configurable optimization plugins
- Integrated into Vite, webpack, Next.js image pipeline
Alternatives and When to Use Them
ImageOptim (Mac app) optimizes SVG via SVGO internally — good for non-technical users who want a GUI. Squoosh (web app) supports SVG preview but focuses on raster optimization. Nano SVG is a lightweight SVG parser, not an optimizer. For automation: SVGO is the only option; for GUI: ImageOptim or online tools like svgomg.net.
- ImageOptim (Mac): GUI-based, uses SVGO internally, drag-and-drop
- svgomg.net: browser-based SVGO GUI, good for one-off optimization
- Nano SVG: a parser library, not a standalone optimizer
Frequently Asked Questions
How much can SVGO reduce SVG file size?
Typically 20–60% for editor-generated SVG (from Illustrator or Inkscape), which contains metadata bloat. Simple hand-coded SVG has less to optimize. Use --multipass and --pretty for the best output.
Is there a GUI for SVGO that doesn't require a terminal?
Yes — svgomg.net is a browser-based GUI for SVGO with sliders for each plugin. ImageOptim on Mac also runs SVGO internally with a drag-and-drop interface. For Windows, use the svgomg web app.
