Unoptimized SVGs exported from vector editors contain excessive decimal precision, redundant metadata, and nested groups that cause browser layout thrashing.
1. SVG Optimization Checklist
- Decimal Precision Clamping: Reducing coordinate decimals from 6 places to 1 or 2 reduces vector file weight by 55% with zero perceptible visual degradation.
- Path Consolidation: Merging overlapping paths into unified Bezier commands (
M,C,Z) eliminates redundant drawing operations. - SVG Symbols & External Sprites: Using
<svg><use href="#icon-id" /></svg>prevents embedding identical XML definitions across multiple DOM nodes.
