Compress SVG online to strip unnecessary metadata, comments, and redundant attributes that bloat file size. Upload your SVG, preview the cleaned result, and download the optimized file. This free browser-based tool uses proven optimization passes and requires no signup or server upload.
The SVG Optimizer reduces SVG file size by removing unnecessary elements, attributes, whitespace, and redundant data that design tools add but browsers do not need to render the image. Exporting SVG from Illustrator, Inkscape, Figma, or Sketch often includes metadata like editor-specific attributes, empty groups, unused definitions, and doctype declarations that significantly increase file size without affecting the visual output. This tool applies a set of configurable optimization passes: removing comments, removing editor metadata, collapsing empty tags, converting colors to shorter hex notation, merging path segments where possible, removing unnecessary namespaces, and stripping xmlns attributes from inline SVG. The output is a smaller SVG file with identical visual appearance. File size reduction and original size are shown after optimization.
SVG files exported from design tools can be surprisingly bloated. A simple icon exported from Adobe Illustrator might be 8 KB as exported but only 1.5 KB after optimization, a reduction of over 80 percent. This happens because design tools include extensive metadata: the Illustrator-specific AI namespace with document settings, layer names as Inkscape labels, the Figma-generated ID for every element, the XML declaration and DOCTYPE, and whitespace-formatted output for human readability. None of this is needed by a browser to render the image correctly. SVGO (SVG Optimizer) is the industry-standard tool for this task, used internally by most build pipelines including Webpack, Vite, and create-react-app. This browser-based tool applies the same SVGO optimization passes without requiring a local installation. The key optimizations by size impact are: removing whitespace and formatting (typically 10 to 20 percent reduction), removing editor metadata and comments (5 to 20 percent), removing unused definitions and empty groups (variable, can be large for complex files), and path data precision reduction (rounding coordinate values to fewer decimal places, typically 3 to 5 percent). For web performance, smaller SVG files improve page load speed when SVG icons are used extensively (a site using 50 inline SVGs each saving 5 KB saves 250 KB total). For sprite sheets that combine many icons, optimization before merging produces the most compact result.
