Why Is My SVG Larger Than My JPEG?
SVG can be tiny for logos and icons, but detailed photos may create thousands of paths and become larger than the original JPEG.

JPEG stores pixels, SVG stores instructions
JPEG is efficient for photos because it stores compressed pixel data. SVG stores paths, fills, shapes, and coordinates. That is perfect for logos and icons, but a detailed photo can require thousands of traced shapes to approximate the original image.
When a converter follows every color edge in a photo, the SVG may become larger than the JPEG. This is normal and does not mean the conversion failed; it means the source image is complex for a vector format.
How to make the SVG smaller
Reduce the color count, lower detail, increase smoothness, enable simplify paths, and use Ultra Light mode. Cropping the image before conversion also helps because the tracer has fewer pixels and fewer edges to analyze.
For website use, ask whether the image really needs SVG. Photos often belong in JPEG or WebP, while logos, icons, signatures, sketches, and simple graphics are usually better SVG candidates.
FAQ
Is it bad if SVG is larger than JPEG?
Not always. It is common for detailed photos, but for web performance you may want to reduce colors and detail.
What images make small SVGs?
Logos, icons, signatures, sketches, line art, and simple flat graphics usually create smaller SVGs.
