SVG Optimizer

Free online SVG optimizer — remove editor metadata, comments, and reduce path precision from Figma and Illustrator exports. 100% in-browser, no signup.

Optimization Level

Cleaning Options

Prettify Code

Readable indented output

Path Precision

2 dp

Lower precision results in smaller files but may distort complex shapes.

PRO TIP

Always use 'Balanced' for logos. 'Aggressive' can sometimes merge layers that need separate animation IDs.

Your SVG files are never uploaded. All optimization runs entirely in your browser.

30–70% Smaller

Removes editor metadata, comments, and redundant elements without changing the visual output.

Configurable Presets

Choose Safe, Balanced, or Aggressive optimization — or tune individual options manually.

100% Private

No upload to any server. Your SVG files never leave your device.

SVG Optimizer Online — Minify, Clean & Compress SVG Free

Every SVG you export from Figma, Adobe Illustrator, or Sketch carries hidden baggage: editor metadata, software-specific namespace declarations, verbose decimal coordinates, and layer IDs that mean nothing to a browser. This free SVG optimizer strips all of it, reducing file size by 30–70% without changing a single pixel of the visual output.

Paste your SVG code directly or drag-and-drop a file. Choose your optimization level — Safe, Balanced, or Aggressive — and see the before/after stats instantly. No server upload, no signup, no file size limits. Everything runs in your browser using the Web APIs.

How to Use the SVG Optimizer

  1. Paste or upload your SVG — drag and drop a .svg file onto the upload zone, or paste the raw SVG code directly into the text area below it.
  2. Choose an optimization level — Safe keeps all IDs and skips path rounding, Balanced (recommended) removes unused IDs and rounds coordinates to 2 decimal places, Aggressive applies all optimizations for maximum reduction.
  3. Toggle individual options — fine-tune by enabling or disabling Remove Comments, Remove Metadata, Remove Unused IDs, and Minify Paths independently.
  4. Preview the result — switch to the Optimized View tab and click Preview to render the optimized SVG and verify nothing changed visually.
  5. Export or copy — click "Optimize & Copy" to copy to clipboard, or "Export .svg" to download the optimized file.

Why SVG Files Are So Large After Exporting from Design Tools

Design tools are built for editing, not delivery. When Figma exports an SVG, it embeds:

  • Editor namespace declarations — xmlns:figma="http://www.figma.com/figma/1.0" and similar attributes that browsers completely ignore
  • <metadata> blocks — file identifiers, version strings, and artboard information baked in by the exporter
  • Verbose decimal coordinates — path data like d="M15.123456 32.678901" when d="M15.12 32.68" renders identically
  • Empty wrapper groups — <g> elements with no attributes left over from layer grouping logic
  • Unused <defs> entries — clip paths and gradients defined but never referenced in the final output
  • Layer IDs — id="Figma_Layer_234891" strings that served the editor but have no purpose on the web

A typical icon exported from Figma is 2–5× larger than it needs to be. The optimizer removes all of this overhead while leaving the geometry, colors, and structure untouched.

Safe vs. Balanced vs. Aggressive Optimization

Safe preset — removes comments, metadata blocks, and editor namespace attributes. Keeps all IDs intact (important if you reference them from CSS or JavaScript). Rounds coordinates to 3 decimal places. Average reduction: 20–40%.

Balanced preset (recommended for most SVGs) — everything in Safe, plus removes unused IDs and rounds coordinates to 2 decimal places. Safe for icons, logos, and illustrations that don't have external CSS dependencies. Average reduction: 40–60%.

Aggressive preset — everything in Balanced, plus rounds coordinates to 1 decimal place for maximum file size reduction. Best for simple icons. Avoid for complex illustrations with tight coordinate precision or CSS animations that target element IDs. Average reduction: 50–70%.

Common Use Cases

  • Web performance optimization: Every kilobyte saved from SVG icons and logos reduces page weight and improves Core Web Vitals scores, especially LCP.
  • Figma and Illustrator export cleanup: Remove the proprietary metadata layers that design tools add automatically, making your SVG portable and framework-agnostic.
  • React and Vue component preparation: Optimized, ID-cleaned SVG code is easier to paste as a JSX/TSX component — shorter, cleaner, without namespace conflicts.
  • Icon library maintenance: Process entire sets of icons to consistent quality without needing a local SVGO setup.
  • Email and CMS embedding: Smaller inline SVGs stay within size budgets for email HTML and content management systems that impose payload limits.

Frequently Asked Questions

What is an SVG optimizer and what does it actually do?

An SVG optimizer removes unnecessary data from SVG files without changing how they render. This includes editor metadata, software comments, redundant XML namespace declarations, excessive decimal precision in path coordinates, and unused <defs> entries. The output is a smaller, cleaner file that loads faster on the web — with the same visual result.

Why are SVG files exported from Figma or Illustrator so large?

Design tools add significant data overhead to SVG exports to support round-tripping the file back into the editor. This includes layer metadata, namespace declarations, editing history hints, and verbose attribute values. None of this is needed by browsers to render the image. A typical Figma icon export is 2–5× larger than the minimum needed for display.

Is SVG optimization lossless?

The Safe and Balanced presets are lossless — the SVG renders identically before and after optimization. The Aggressive preset includes path coordinate rounding which is visually imperceptible for most shapes but may introduce sub-pixel differences in complex curves. Always verify with the visual Preview tab before shipping.

Should I remove the viewBox attribute during optimization?

No. The viewBox attribute is essential for SVG scalability — it defines the internal coordinate system and allows the SVG to scale responsively with CSS. Removing viewBox forces the SVG to render at fixed pixel dimensions, breaking responsive layouts. This optimizer never removes viewBox regardless of the settings chosen.

How do I reduce SVG file size without quality loss?

Use the Balanced preset: it removes editor metadata, comments, and unused IDs, and rounds path coordinates to 2 decimal places. This combination typically reduces file size by 40–60% with zero visual impact. For further reduction, enable Aggressive mode and verify the Preview output carefully. If your SVG has CSS animations that reference element IDs, use Safe mode to avoid breaking those references.

How do I use an optimized SVG as an inline React component?

Copy the optimized SVG code using "Optimize & Copy," then paste it directly into a React component return statement. Two manual changes are needed: class attributes become className, and hyphenated attributes like stroke-width become camelCase strokeWidth. The SVG optimizer removes the editor junk so there's less to adapt.
