SVG Optimizer & Minifier

Quick mode never reshapes path geometry, and <title> is preserved in both modes. Deep mode rewrites path data and converts shapes to paths (numerically equivalent, but source changes), and its safe sanitize removes <script> elements — script-driven interactivity will stop working (you can turn it off). Whitespace collapses and number/color values shorten (numerically equal), so give the result a quick check before shipping.

It removes <script> elements. It does not sanitize foreignObject, inline event-handler attributes or javascript: URIs, and fonts are not embedded — review untrusted SVGs separately.

Yes — both modes run in your browser; the SVGO engine loads on demand as a lazy chunk.

Yes — optimization uses the free daily allowance and needs no sign-in. The SVG is processed in your browser and is never uploaded.

Quick is a regex-based appearance-level subset: instant, and it never reshapes path geometry or the viewBox, so it is safe to run on anything. Deep runs the full SVGO v4 plugin set (path rewriting, ID cleanup, transform folding, shapes to paths) and saves more, but rewrites the source — review the before/after render before shipping.

No. Optimization strips redundant markup — comments, editor metadata, empty groups, whitespace, over-precise numbers — but it never reduces the node or point count in a path. To actually simplify geometry (fewer nodes), use a vector editor such as Inkscape's 'Simplify path' or Illustrator's simplify command, then run this tool to minify the result.

It depends on how much editor cruft the file carries: freshly exported SVGs from Illustrator/Inkscape/Figma typically shrink the most, while already-optimized files report a 0% savings note. The gzip column tells you what actually ships over the wire for web use — check it, since gzip erases most of the whitespace savings.

No — it works one file at a time (open, drop, or paste). There is no batch mode and no upload step; for bulk raster images use the batch image compressor instead.
