SVG Optimizer

Why Optimize SVG Files?

SVG files exported from Illustrator, Figma, or Inkscape contain massive amounts of unnecessary data — comments, editor metadata, redundant attributes, overly precise decimal numbers, and empty containers. These inflate file sizes by 30–70% with no visual benefit. Optimized SVGs load faster, consume less bandwidth, and can be inlined more cleanly in HTML.

Safe Optimization

All optimizations preserve the visual appearance of your SVG — only metadata and noise is removed

How to Optimize SVG in 3 Steps

1

Paste SVG Code

Copy the SVG source code from your design tool or file and paste it into the input area

2

Select Optimizations

Check the optimization options you want to apply — or use the defaults for maximum reduction

3

Copy & Deploy

Copy the optimized SVG and replace your original file, or inline it directly into HTML

SVG Optimization Use Cases

🎨

Icon Libraries

Optimize icon sets exported from Figma or Illustrator before bundling into an icon library

🏢

Logo Assets

Clean up exported logo SVGs for use in website headers, favicons, and brand assets

✨

Animated SVGs

Reduce the base file size of animated SVGs, which are already larger due to animation data

📱

PWA & Mobile

Smaller SVGs reduce data usage for mobile users and improve Lighthouse performance scores

SVG Optimization Best Practices

✓ Be Careful Removing IDs for CSS Animations

If your SVG uses CSS or JavaScript animations targeting element IDs, keep the 'Remove IDs' option unchecked to avoid breaking animations.

✓ Keep the viewBox, Remove width/height

Removing width/height attributes and keeping viewBox makes SVGs scale responsively via CSS — the best approach for responsive design.

✓ Round Numbers to 2 Decimal Places

Path coordinates with 5+ decimal places are invisible imperceptible. Rounding to 2 decimal places significantly reduces file size with zero visual difference.

✓ Automate with SVGO in CI/CD

For large projects, integrate SVGO into your build pipeline to automatically optimize all SVGs on commit. Use this tool for quick manual checks.

❓ Frequently Asked Questions

How much can SVG optimization reduce file size?

Typically 30–70% reduction depending on the source. SVGs from Illustrator often have the most savings. Figma exports are already relatively clean. The biggest gains come from removing editor metadata, comments, and rounding decimal precision.

Will optimization change how my SVG looks?

No — all optimizations in this tool only remove invisible data (comments, metadata, redundant attributes) or round numbers to imperceptible precision. The visual output is identical to the original.

Why should I remove width and height attributes?

Hardcoded width/height prevent SVGs from scaling responsively via CSS. By removing them and keeping only viewBox, you can control SVG dimensions entirely through CSS width/height properties.

What is the difference between this and SVGO?

SVGO is a Node.js command-line tool and the industry standard for SVG optimization. This tool provides a convenient browser-based interface for the most common optimizations without requiring Node.js installation.
