Features

Our SVG optimization tool offers a complete set of features for working with SVG files.

Minify SVG

Remove unnecessary whitespace, comments, metadata and hidden elements from SVG files to reduce file size while preserving visual quality.

Unminify SVG

Restore readable formatting to minified SVG code with proper indentation and line breaks for easy editing and debugging.

Optimize SVG

Go beyond minification by removing editor metadata, simplifying paths, and cleaning up unused elements for maximum file size reduction.

How SVG Optimization Works

SVG optimization goes beyond simple minification. While minification removes whitespace and comments, optimization analyzes the SVG structure to remove editor metadata (from tools like Illustrator or Inkscape), simplify path data, merge compatible elements, and strip hidden or unused definitions. This can reduce SVG file sizes by 20-60% without any visual change.

SVG Optimization vs Minification — What's the Difference

Minification is a subset of optimization. Minifying an SVG removes whitespace, line breaks and comments. Optimizing additionally removes metadata, editor artifacts, simplifies coordinates, and cleans unused defs. Both approaches are safe and preserve the visual output. Use our tool for both operations — paste your SVG and click the appropriate button.
