Cleaning up an SVG icon exported by Figma, Illustrator, or Sketch before checking it into a repo. Trimming the payload before inlining it into HTML or CSS (where every byte ships with every page). Stripping the chatty XML comments that some design tools embed in their export ("Generator: Adobe Illustrator…"). Quick sanity-pass before encoding an SVG as a data: URL.

Not as aggressive as SVGO. The real SVGO library can do path optimisation, viewBox cleanup, and dozens of other passes. This tool deliberately does only the safe, obvious passes — to keep it 0-dependency and 100% in-browser. Default-attr dropping is conservative. It only removes a short list of well-known defaults ( stroke="none" , fill-rule="nonzero" , etc.). If your SVG depends on those being explicit (e.g. for CSS-targeted styling), uncheck the option. Coordinate rounding is lossy. Rounding to 2 dp is safe for icons and logos; for high-precision diagrams or charts, you may want to disable it. Whitespace collapse can break . SVG elements that rely on multiple spaces will lose them. For icon SVGs (no text), this is never an issue.

What is this for?

This tool runs a tiny set of hand-rolled regex passes over an SVG to shrink its byte size: it strips XML comments, collapses runs of whitespace between tags, drops a handful of attributes that already match their default values, and rounds long fractional coordinates to 2 decimal places. Each pass is a checkbox you can disable. Everything happens in your browser — no upload, no server.
