Optimize SVGs and convert them to images, in your browser

SVGs exported from Illustrator, Figma, Inkscape or Sketch are often two to three times larger than they need to be — full of editor metadata, comments and over-precise coordinates. Poly3D's SVG optimizer strips that cruft and rounds numbers to shrink the file while keeping it pixel-identical. Need a raster instead? Switch to rasterise and export a crisp PNG, JPG or WebP at 1×, 2× or 3× — or an exact pixel width. It all happens on your device with the browser's own DOM and Canvas, so your artwork is never uploaded.

Frequently asked questions

Are my SVG files uploaded to a server?

No. Everything runs locally in your browser — the SVG is parsed, optimized or rasterised on your own device with the DOM and Canvas APIs. Your files never leave your computer.

What does “optimize” actually do?

It strips the parts that bloat SVGs exported from editors — comments, metadata, editor-specific tags and attributes (Inkscape, Illustrator, Sketch), the XML declaration — and rounds long coordinate numbers to a precision you choose. The visual result stays the same while the file gets smaller.

Can I convert an SVG to a PNG?

Yes. Switch to “Rasterise”, pick PNG, JPG or WebP, and set a scale (1×, 2×, 3×) or an exact output width. Because SVG is vector, you can export it crisply at any resolution — 2× or 3× for retina screens.

Will PNG keep the transparent background?

Yes. PNG and WebP preserve transparency. JPG has no transparency, so transparent areas are filled with white when you export to JPG.

Can I process many SVGs at once?

Yes. Drop multiple SVGs, choose one set of settings, process them all, and download the results together as a .zip file.
