The SVG Minifier & Optimizer is a free online tool for compressing and optimizing SVG vector image files. By removing redundant data (comments, whitespace, default attributes, metadata, editor info, etc.), it significantly reduces file size without affecting visual output. It supports multiple optimization options that can be toggled on/off, provides real-time preview and compression statistics, and all operations run locally in your browser — your files are never uploaded to any server.
1. Input SVG: Paste SVG code in the text box, or drag & drop an SVG file
2. Select optimization options: Check the desired options — recommended defaults are pre-selected
3. Click "Minify & Optimize" to run compression, or it auto-triggers on input
4. View results: Minified SVG code appears in the output area with preview below
5. Export: One-click copy the minified SVG code, or download as .svg file
Frontend developers compress SVG icons and illustrations before embedding them in web pages, reducing HTTP requests and data transfer for faster page loads.
SVGs exported from Illustrator, Figma, and similar tools contain abundant editor metadata and default attributes. This tool cleans them up for leaner handoffs to dev teams.
When maintaining SVG icon libraries, batch-compressing all icons keeps the library size minimal, improving npm download speed and CDN performance.
Mobile apps are sensitive to resource size. Compressing SVG assets reduces app install size and saves user bandwidth.
SVG (Scalable Vector Graphics) is an XML-based vector format that inherently contains verbose text data. Common sources of redundancy include editor metadata (e.g., Illustrator namespaces), default attribute values (e.g., fill="#000"), formatted whitespace and indentation, comments, and unused definitions. SVGO is the most popular Node.js SVG optimization tool; this tool implements its core optimization logic as a browser-side version that requires no installation.
SVG minification reduces file size by removing redundant data (comments, whitespace, default attributes, metadata) without affecting the visual output.
Typically 20%-50%, depending on the original SVG's redundancy. SVGs with lots of comments and default attributes see greater savings.
No. SVG minification is lossless — it only removes data that doesn't affect rendering. The minified SVG looks identical to the original.
8 options: remove comments, metadata, default attributes, compress path data, collapse whitespace, simplify colors, remove editor data, and remove unused IDs.
No. All optimization runs locally in your browser. Your SVG files never leave your device.
Yes. You can drag & drop multiple SVG files or paste multiple SVG codes for batch processing.
Yes. Real-time preview is shown after minification so you can verify the visual output is identical to the original.
