SVG Optimizer: Compress and Clean SVG Files

SVG files are great for web graphics — they scale to any size without getting blurry. But SVGs exported from design tools like Figma, Illustrator, or Sketch often contain a ton of unnecessary junk. Editor metadata, hidden layers, redundant attributes, comments nobody will ever read. The SVG optimizer strips all of that out.

What Gets Removed

The SVG optimizer cleans up your files by removing several categories of bloat:

• Editor metadata — Illustrator, Sketch, and Figma all embed their own data in SVGs
• Comments — XML comments that serve no purpose in production
• Hidden elements — layers with display:none that are invisible anyway
• Redundant attributes — default values that don't need to be specified
• Empty groups — container elements with nothing in them
• Unnecessary precision — coordinates with 15 decimal places trimmed to 2

The visual output stays identical. You're only removing things the browser ignores anyway.

Why SVG Optimization Matters

Every SVG on your page is HTML that the browser has to parse. Bigger SVGs take longer to load and longer to render. If you have icons, logos, or illustrations as SVGs (and you should), optimizing them makes your site faster.

I've seen SVG icons go from 15KB to 2KB after optimization. When you've got 20 icons on a page, that's a noticeable difference in load time.

How to Use the SVG Optimizer

Paste your SVG code or upload the file. The tool processes it and shows you the optimized version alongside the original. You can see exactly how much smaller the file is — both in bytes and as a percentage.

Preview the optimized SVG to make sure it still looks right. In rare cases, aggressive optimization can affect certain gradients or filters, so it's always worth a quick visual check.

When to Optimize

Optimize every SVG before adding it to your website. Make it part of your workflow: export from your design tool, run through the optimizer, then add to your project. Some build tools can automate this, but for one-off optimizations, the online tool is faster than configuring a whole pipeline.

Also useful if you're receiving SVGs from a designer and they're larger than expected. Run them through the optimizer before asking for re-exports — the problem is usually just metadata bloat.
