Paste SVG markup to remove scripts, event handlers, foreignObject, iframes, embeds, and external href/src references, then minify whitespace. Sanitization is intentional and conservative for safer SVG use. Processing stays on your device.
How to use this tool
1. Paste SVG markup or upload an .svg file. 2. Choose optimization options such as removing comments or metadata if shown. 3. Click Optimize. 4. Compare original and optimized file size in the results panel. 5. Copy or download the optimized SVG. Processing runs on your device.
Worked example
Example: paste a 12 KB icon SVG with editor metadata and download a smaller cleaned file for web use.
How it works
Paste SVG markup to sanitize and minify it locally. The optimizer removes script tags, event-handler attributes (onclick and similar), foreignObject, iframes, embeds, and external href/src references. Comments and extra whitespace are stripped. Processing stays on your device.
Limitations
Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.
