Clean SVG Code

The Zynocode Labs SVG Optimizer is a browser-based vector compression and minification suite built for frontend developers, UI/UX designers, and performance engineers. Scalable Vector Graphics (SVG) exported from graphic design applications—such as Adobe Illustrator, Figma, Sketch, and Inkscape—frequently contain megabytes of redundant metadata, editor proprietary namespaces, XML comments, and excessively precise floating-point coordinates. Our optimization engine analyzes the document object tree, purging bloat while preserving mathematical visual accuracy and responsive scaling behavior.

Powered by In-Browser SVGO: Under the hood, the optimizer leverages the battle-tested SVGO (SVG Optimizer) engine compiled directly for client-side browser execution. You get industry-standard compression algorithms directly in your browser without transmitting your brand icons, illustrations, or vector artwork across the internet.

Preserve viewBox Guarantee: Many automated minifiers inadvertently strip or corrupt the viewBox attribute, breaking fluid responsiveness when vector graphics are rendered inside responsive CSS containers or <img> tags. Our optimizer strictly preserves and locks the viewBox coordinate system, ensuring your optimized icons scale cleanly across mobile viewports, high-density Retina displays, and desktop monitors.

Configurable Coordinate Rounding & Precision: Vector editors often save coordinate path points with 6 to 10 decimal digits of precision (e.g., 100.12345678), creating bloated path strings that offer zero discernible visual improvement to the human eye. With our decimal rounding selector, you can round coordinates to 1, 2, or 3 decimal places, dramatically truncating path command strings (d="M...") which often makes files noticeably smaller; the exact saving depends on how the SVG was exported and is shown before and after.

Sanitized Previews & Zero Script Execution: Security is paramount when working with XML-based vector graphics. Malicious SVGs can embed <script> tags or inline JavaScript event handlers (like onload). Our preview interface processes SVG output through DOMPurify and renders visual feedback exclusively inside sandboxed data URI image elements. Scripts can never execute in your session, making it completely safe to inspect third-party vector files.

Live Side-by-Side Visual Inspection: Compare your original vector graphic against the optimized result with instant side-by-side rendering cards. Check exact before-and-after byte weights, net kilobyte reduction, and percentage savings in real time.
