Supports standard vector .svg files up to 5MB
Zero Server Uploads: This tool utilizes standard browser XML parsing libraries to optimize your vector graphics strictly locally inside your browser cache. Zero files or data are uploaded.

How to Use

1

Upload SVG

Drop your SVG file or paste the raw XML code.

2

Set Precision

Adjust coordinate float rounding to balance file size and visual details.

3

Download Clean SVG

Download the optimized vector graphic with full transparency and zero metadata.

Real-World Examples & Use Cases

Web Performance Optimization

Large vector illustrations exported directly from graphics software like Illustrator often contain redundant metadata and bloated coordinate paths. Optimizing SVGs before publishing reduces site asset load times, speeds up initial page paint, and improves Lighthouse/Core Web Vitals scores.

Responsive Design Assets

SVGs are ideal for responsive websites, but hidden sizing attributes (`width`, `height`) can override responsive CSS rules. The optimizer lets you convert rigid dimensions into flexible `viewBox` settings, making vectors scale cleanly on all displays.

Cleaning Vector Exports for React/Vue

When rendering SVGs inline in frontend frameworks (like React components), editor-specific tags (like `sodipodi:namedview` or namespaces) can throw console warnings or break compilation. Sanitizing SVGs ensures clean component integration.

How It Works

SVG Minification and Vector Cleanup Rules: SVG (Scalable Vector Graphics) is an XML-based format. The optimizer processes the XML DOM tree using a set of rule passes: 1. Namespace & Editor Metadata Strip: Removes metadata wrappers, namespaces, and tags generated by vector editors (like Inkscape, Adobe Illustrator, or Sketch) including: - <metadata>, <defs>, sodipodi attributes, and XML comments. 2. Coordinate Decimal Precision Rounding: Standard vector paths contain high-precision decimals (e.g., d="M10.12345,20.98765"). Reducing decimal precision (e.g., rounding to 2 decimal places: d="M10.12,20.99") significantly reduces string length and file size without visible changes in vector paths. 3. Node Minification: Removes unused attributes (like redundant IDs, default values, empty elements, and trailing spaces), minifies style sheets, and merges paths where mathematically possible. 4. Dimensional Normalization: Extracts absolute width and height attributes and injects them into the responsive `viewBox` attribute if not already present.

Frequently Asked Questions

What editor metadata does this tool remove?
It strips Illustrator, Inkscape, Sketch, and Figma namespace elements, sodipodi nodes, XML schemas, comments, editor variables, and default XML namespaces that are purely used by designers to save local progress but are ignored by browsers during rendering.
Will reducing path decimal precision ruin my graphic?
Rarely. Standard illustrations look identical at a decimal precision of 2 or 3. If you have extremely detailed micro-graphics or complex icons, you can set the precision slider to 4 or 5. For standard icons and website illustrations, 2 is recommended for maximum file savings.
How is this tool different from SVGO?
This tool performs similar XML minification passes to the popular SVGO node package but executes entirely client-side in the browser. It gives you a live file size comparison and code editor view without requiring command-line installations.
Why does ConvertWithMi prioritize client-side SVG optimization?
SVGs are text files that can technically contain embedded malicious JavaScript (via `<script>` tags). Using remote services to optimize SVGs requires uploading vectors, which poses security and IP leakage risks. Client-side processing keeps your proprietary artwork and source vectors entirely on your local machine.
