Optimize SVG Online — SVGO Presets in Your Browser
Deep-optimize SVG with SVGO safe, default or aggressive presets. Goes beyond quick minify — all processing stays local.
Developer notes
• SVGO loads on demand (~780 KB) only when you optimize — not on minify-svg pages. • Safe keeps paths and IDs intact; aggressive may merge paths for smaller output. • Input is capped at 512 KB to keep the tab responsive. • For quick whitespace removal without SVGO, use minify-svg instead.
Options
When teams pick this route
• Shrink Figma or Illustrator exports before shipping icons. • Compare safe vs aggressive output on marketing illustrations. • Prep sprite candidates while keeping title/desc for accessibility. • Batch-check one asset at a time without CLI setup.

SVGO presets in the browser
When to use minify-svg vs optimize-svg?
Use minify-svg for instant regex whitespace removal. Use optimize-svg when you need SVGO path cleanup and preset-controlled depth.
Which preset should I choose?
Safe for icons with IDs, default for most production assets, aggressive when byte size matters more than path fidelity.
Is my SVG uploaded?
Never — SVGO runs locally after the library loads.
Large files?
Inputs above 512 KB are rejected with a clear message to protect browser memory.
