SVG Optimization Techniques Every Developer Should Know in 2026

SVG files are incredibly powerful for web graphics—they're scalable, styleable with CSS, and typically smaller than raster alternatives. But poorly optimized SVGs can be larger than PNGs and slow down your site.

Here's how to optimize them properly.

Why SVG Optimization Matters

An unoptimized SVG exported from Illustrator or generated by an AI tool can contain:

A 50KB SVG can often become 8KB after optimization—an 84% reduction.

Technique 1: Remove Metadata

Most design tools embed metadata:

Safe to remove:

Technique 2: Simplify Paths

Paths with excessive precision waste bytes:

For most web use, 1-2 decimal places is sufficient.

Technique 3: Use Path Shorthand

SVG path commands have shorthand versions:

| Long | Short | Meaning | |------|-------|--------| | L 10 20 | l 10 20 | Relative lineto | | H 10 | h 10 | Horizontal line | | V 20 | v 20 | Vertical line | | Z | z | Close path |

Technique 4: Consolidate Styles

Inline styles repeat across elements:

Technique 5: GZIP Compression

SVG is text-based and compresses extremely well:

| File | Raw | Gzipped | Savings | |------|-----|---------|--------| | Logo.svg | 15KB | 3KB | 80% | | Icons.svg | 45KB | 8KB | 82% |

Ensure your server sends Content-Encoding: gzip for SVG files.

Technique 6: Use SVGO

SVGO is the standard tool for SVG optimization:

npm install -g svgo
svgo input.svg -o output.svg

Technique 7: SVG Sprites for Icons

Instead of loading 20 separate icon files, create a sprite:

Use with :

Real-World Example

| Stage | Size | Reduction | |-------|------|----------| | Original (Illustrator) | 48KB | — | | After SVGO | 12KB | 75% | | After manual cleanup | 8KB | 83% | | Gzipped | 2KB | 96% |
