Optimizing SVG Graphics for Web Performance and Live Previewing
Vector graphics exported from Illustrator, Figma, or Sketch contain heavy XML comments, editor metadata, redundant namespaces, and unnecessarily high-precision path coordinate floats.
Optimize and preview your vector graphics:
- Reduce vector file sizes with the SVG Optimizer
- Live preview, inspect viewBox, and test background contrast with the SVG Previewer
Key SVG Optimization Passes
- Remove Doctype, XML Declarations, & Comments: Strips non-rendering header overhead.
- Clean IDs and Unused Defs: Removes unused gradients, clip paths, and masks.
- Round Path Coordinates: Trims numbers like
d="M 12.345678 45.678912"to 2 decimal places (d="M 12.35 45.68"). - Convert Attributes to Shorthands: Combines
stroke-width,fill, and transforms.
Optimize vector assets in seconds with the SVG Optimizer.
