About SVG Optimizer
SVG Optimizer is a free online tool that cleans and minifies SVG code without relying on external libraries. It removes editor metadata (from Illustrator, Inkscape, Sketch), XML declarations, DOCTYPE, HTML comments, empty groups, and redundant attributes. The tool also shortens decimal precision in numeric values to reduce file size while preserving visual fidelity.
How to Use
- Paste SVG code — Copy your SVG source code and paste it into the input textarea.
- Click Optimize — Press the Optimize button to process the SVG code.
- Compare sizes — View the original vs optimized file sizes and the percentage of savings.
- Preview the result — Check the optimized SVG preview to verify it looks correct.
- Copy or download — Copy the optimized SVG to clipboard or download it as a .svg file.
Frequently Asked Questions
Q: Is my SVG data secure?
Yes. All optimization happens entirely in your browser using regex-based processing. No SVG data is ever sent to any server.
Q: What does the optimizer remove?
It removes XML declarations, DOCTYPE, HTML comments, editor metadata (Illustrator, Inkscape, Sketch namespaces), duplicate xmlns attributes, empty groups, empty id/class attributes, and unnecessary whitespace. It also reduces decimal precision in numeric values.
Q: Will optimization break my SVG?
The optimizer only removes non-visual metadata and redundant elements. Always preview the result to verify. If your SVG relies on specific editor metadata or custom namespaces, those may be removed.
Q: How much size reduction can I expect?
Results vary depending on the SVG source. Files exported from design tools like Illustrator or Figma often contain significant metadata, achieving 10-50% size reduction. Hand-written or already-clean SVGs may see minimal improvement.
Q: Does it use SVGO or other libraries?
No. This tool uses a lightweight regex-based approach that runs entirely in the browser without any external dependencies. This ensures fast processing and complete privacy.
