Convert JPG to SVG

JPG and SVG are fundamentally different kinds of images. JPG stores a grid of pixels with lossy compression, optimised for photographs. SVG stores mathematical descriptions of shapes, paths, and curves — it's resolution-independent and can scale to any size without quality loss. Converting JPG to SVG isn't really 'converting' in the format-translation sense — it's tracing: algorithmically approximating the pixel data with vector shapes that cover the same visual territory.

Tracing works well for simple, high-contrast images: logos, icons, line drawings, pixel art, hand-drawn sketches with clear outlines. The algorithm finds edges, fits curves to them, and groups regions of similar colour into filled shapes. The resulting SVG is small, sharp, and infinitely scalable. For these inputs, SVG is genuinely the right format — it's the difference between a logo that looks crisp on a billboard versus one that pixelates the moment you enlarge it.

Tracing fails — or rather, produces output you don't want — for photographs. A photograph has thousands of subtle colour gradients and millions of unique colour values. A vector approximation of a photograph requires either a comically large number of paths (resulting in an SVG many times larger than the source JPG with no visual benefit) or aggressive simplification that loses the photograph's character entirely. If you're converting a photo, SVG is almost certainly the wrong target — stay with JPG, or convert to PNG/WebP if you need transparency or lossless quality.

MegaConvert's tracer applies a posterisation step before tracing (reducing the colour count to a manageable palette), then traces each colour region as a separate filled path. You can think of it as 'how would a stencil-cut version of this image look?' For brand marks, simple illustrations, and sticker-style graphics, the result is faithful and scalable. For complex photographic content, you'll see the algorithm's approximation rather than a faithful reproduction.
