Free Online SVG Optimizer & Minifier
Scalable Vector Graphics (SVGs) created in editors like Adobe Illustrator or Figma often include massive amounts of hidden, useless data: editor metadata, XML declarations, empty tags, hidden elements, and unneeded whitespace. This bloats file sizes, slowing down website loading times. Our SVG Optimizer strips all of that away instantly, drastically reducing file size without altering the visual output.
How to use the SVG Minifier
- Input your SVG: Either paste raw SVG code directly into the left-hand text
area, or click "Upload File" to select an
.svgfile from your computer. - Click Optimize: Hit the "Optimize SVG" button. The tool will parse the code, strip extraneous information, and output a clean, production-ready minified string on the right.
- Review & Export: Note the percentage of bytes saved in the top right. View the visual preview to ensure the graphic remains intact. Then, either copy the raw code or download the minified file.
What gets removed?
- XML processing instructions & Doctype
declarations (e.g.
<?xml...>and<!DOCTYPE...>) - HTML/XML Comments
(
<!-- comments -->) - Editor Metadata: Namespaces and tags specific to Adobe Illustrator, Sketch, or Inkscape.
- Whitespace: Extraneous line breaks, tabs, and spaces.
Frequently Asked Questions
Will optimizing my SVG affect its visual quality?
No. This optimizer performs "safe" structural minification. It removes non-rendering
metadata and formats the code tighter, but it does not alter the actual vector paths or
coordinate data. Your image will look exactly the same but weigh much less.
Why did the script fail to parse my SVG?
If you pasted a fragment of code rather than a complete, valid XML document (starting with
an
<svg> tag and ending with </svg>), the browser's
DOM parser will reject it. Ensure you are uploading or pasting a complete SVG.
