SVG Optimizer
FreeReduce SVG file size by removing unnecessary code
About SVG Optimizer
Hand-written and exported SVGs are notoriously bloated. Illustrator, Figma, and Sketch all leave behind editor metadata, redundant groups, excessive decimal precision, and unused defs that inflate file size and slow down page rendering. The SVG Optimizer strips all of that noise while keeping the vector visually identical, so your icons and illustrations stay crisp but ship lighter.
Paste or upload your SVG and the optimizer rewrites the markup: it trims path coordinate precision, collapses transforms, removes comments and editor cruft, and cleans up attributes. Everything runs in your browser with no signup and no watermark, so your artwork never sits on a third-party server. You get the optimized output instantly, ready to drop straight into your markup or asset pipeline.

FAQ
Will optimizing change how my SVG looks?
No. The optimizer only removes redundant or invisible data like metadata, comments, and excess decimal precision. The rendered vector stays visually identical.
Can it break SVGs that rely on specific IDs?
It can rename or remove unused IDs, which may affect SVGs styled by external CSS or controlled by JavaScript. Test those cases after optimizing and keep your original file as backup.
Does it animate or convert the SVG to another format?
No. It keeps the file as an SVG and only cleans the existing markup. The output is still a fully editable vector.
Can I use SVG Optimizer on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
