SVG Optimizer

Run SVGO 4 in the browser with Safe, Balanced, Aggressive or a fully custom per-plugin configuration, then take the result further: export a React, Vue or Svelte component with props spread and camelCased attributes, a UTF-8 or base64 data URI, a CSS background-image rule, a <symbol> sprite sheet, or PNGs at any sizes including a favicon set. Convert fills to currentColor, prefix IDs, inject an accessible title and role, compare before/after markup and gzip sizes, and process many files in batch.

Frequently asked questions

Safe and Balanced keep rendering identical; Aggressive can alter output (it removes dimensions, off-canvas paths and titles). Plugins marked "risky" in the checklist are the ones that can affect appearance or CSS/JS hooks.
