What is Svg optimizer?
SVG Optimizer — Optimize SVG code online with the SVGO engine — minify and clean vector files to cut bytes while keeping the same look. Free SVG optimizer, no signup.
Optimization is done by SVGO v4.1.0 (MIT), the standard open-source SVG optimizer — its plugin pipeline removes editor metadata, comments, hidden elements, and redundant attributes, and collapses paths and transforms. Honest limits: SVGO only rewrites markup; it cannot improve a drawing that is inefficient by design, and multipass adds extra passes at the cost of slightly slower runs. Nothing here is hand-written: every saved byte comes from the SVGO engine.

How to use SVG Optimizer
- 1Paste your SVG markup into the "SVG code" box.
- 2Tick "Extra optimization passes" (multipass) for a deeper clean on stubborn files.
- 3Run the tool — SVGO optimizes the markup in your browser, nothing is uploaded.
- 4Preview the optimized SVG and compare the original vs. optimized byte counts.
- 5Download the optimized SVG and drop it into your site or design tool.

Good to know
- SVGO only rewrites markup — it cannot improve a drawing that is inefficient by design (excessive anchor points, embedded rasters, heavy filters).
- Input must be raw SVG markup starting with <svg; the tool does not fetch SVGs from URLs.
- Multipass runs extra optimization passes for deeper cleaning; it is slightly slower and marginally more likely to touch hairline details — preview the result.
- Byte counts are UTF-8 bytes of the pasted code, which is what browsers download.
How it works
Optimization is done by SVGO v4.1.0 (MIT), the standard open-source SVG optimizer — its plugin pipeline removes editor metadata, comments, hidden elements, and redundant attributes, and collapses paths and transforms. Honest limits: SVGO only rewrites markup; it cannot improve a drawing that is inefficient by design, and multipass adds extra passes at the cost of slightly slower runs.

Examples
Status: ok — comments and redundant attributes are stripped, the icon looks identical.
Status: ok — multipass collapses the no-op group and transform for extra bytes saved.
