How to Reduce SVG File Size
Large SVGs are usually caused by too many paths, too many colors, or too much traced detail from a complex source image.

The fastest fixes
Use Ultra Light mode, reduce colors to three or four, lower detail, increase smoothness, and keep simplify paths enabled. These changes usually reduce path count and markup size more than any after-the-fact cleanup.
If the converter shows a Large or Too Heavy verdict, use the Reduce File Size button. It applies lighter settings and reruns conversion so you can compare the result immediately.
Know when SVG is the wrong target
SVG is excellent for logos, icons, sketches, signatures, line art, cut files, and simple graphics. It is not always the best format for photos. A detailed photo may be smaller and more faithful as JPEG or WebP.
For production websites, choose the smallest file that still looks good at the sizes where people will actually see it. Use preview, zoom, path count, and file size together rather than chasing one metric alone.
