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.

SVG optimizer — SVGO playbook
Deep-optimize SVG with SVGO presets beyond quick regex minify. Choose safe, balanced or aggressive reduction — everything stays in your browser.

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

SVGO preset
Choose Safe (minimal risk), Default (balanced SVGO), or Aggressive (max size reduction — may alter visuals). Default starts on Default.

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.

SVG optimizer FAQ

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.
