SVG Optimizer
Last updated:
Clean pasted SVG markup by removing selected metadata, comments, editor-specific data, and empty groups, with optional numeric rounding and root width/height removal. Preview and compare the result before use.
Runs in your browser. Your artwork is never uploaded.

How the SVG Optimizer Works
- Paste your SVG, straight from Illustrator, Figma, Sketch, or any export.
- It parses the XML, building a real SVG document in the browser.
- It cleans and rounds, removing metadata and trimming long decimals.
- Copy or download, grab the smaller file and see how much you saved.
Why Optimizing SVG Matters
- Faster pages, smaller SVGs reduce bytes on critical icons and logos.
- Cleaner code, inline SVG is easier to read and style without editor cruft.
- Responsive icons, removing fixed dimensions lets SVGs scale with CSS.
- Better Core Web Vitals, lighter assets help LCP and overall load time.
Trimming SVGs is one small win in a much bigger picture, and squeezing every asset for speed is exactly what our website speed and performance optimization work is built around.
What SVG Optimization Removes
Design tools export SVGs with extra data that browsers do not need to draw the image. Removing it produces a smaller, cleaner file that renders identically. This is the same asset-by-asset care behind our website speed and performance optimization service.
| Option | What this tool does | Note |
|---|---|---|
| Selected metadata and editor data | Removes metadata elements, data-name attributes, and recognized Inkscape, Sodipodi, RDF, DC, and CC elements or namespaces. | It does not recognize every editor's private data. |
| XML comments | Removes XML comment nodes when “Remove metadata and comments” is enabled. | Comments are preserved when that option is disabled. |
| Empty groups and defs | Removes g and defs elements that have no child nodes. | Hidden or non-empty elements are not removed. |
| Excess decimal precision | Rounds decimal numbers throughout the serialized SVG to the selected precision. | This is not limited to path coordinates; inspect detailed, animated, or scripted SVGs carefully. |
| Unused definitions, IDs, and classes | Not removed. The tool does not trace references in CSS, scripts, gradients, masks, symbols, or sprites. | Use a reference-aware optimizer plus visual regression tests for that cleanup. |
Savings are qualitative and depend on the source. Exports straight from design tools shrink the most, while hand-written or already-cleaned SVGs gain less. Always verify animated or scripted SVGs after optimizing.
