Frequently Asked Questions

How much does SVG optimization reduce file size?▾

Typically 30–70% depending on the source. SVGs exported from Illustrator or Inkscape contain large amounts of editor metadata, XML declarations, and formatting whitespace. Removing these yields the largest gains.

Does optimization affect the visual appearance?▾

The safe options (remove comments, metadata, editor data, empty elements, minify whitespace) never affect visual output. Destructive options like removing viewBox or shortening IDs can break scaling or CSS references — preview carefully.

Is my SVG uploaded to a server?▾

No. All processing happens in your browser using the DOMParser and XMLSerializer APIs. Your SVG content never leaves your device.

What editor namespaces are removed?▾

Inkscape (xmlns:inkscape, xmlns:sodipodi), Adobe Illustrator (xmlns:x, xmlns:i, xmlns:graph, i:pgf), and Sketch (xmlns:sketch) namespaces and their prefixed elements and attributes.

Should I use this instead of SVGO?▾

For one-off optimization, yes — this tool is instant and browser-based. For production build pipelines (Webpack, Vite, Rollup), use SVGO CLI which applies more advanced path optimizations and can be automated.
