Raster to Vector Conversion

The technical name for what designers ask for daily: turning pixel images into geometric paths. Our engine does it with sub-pixel edge accuracy and publishes its benchmark numbers openly.

How the engine actually works

Five stages: perceptual color clustering (Lab space, ΔE merging) → shared-boundary extraction on the pixel lattice (each border traced once, used by both regions — the step most tools skip) → corner detection with non-maximum suppression → least-squares Bézier fitting with a wild-curve fuse → sub-pixel snapping of every boundary point to the true 50% color transition in your original image. Smooth shading becomes real SVG linear gradients where detected.

In our open 50-logo blind benchmark this beats vtracer (the strongest open-source engine) by 19% overall fidelity and 41% on real-world colorful logos. We publish the numbers because we'd rather earn trust than claim it.

Frequently asked questions

What's the difference between raster and vector?
Raster = pixels (PNG, JPG): fixed resolution, blurs when scaled. Vector = geometry (SVG, EPS, PDF paths): mathematical curves, sharp at any size. Conversion means re-deriving the geometry from the pixels.
What formats can I download?
Every vectorization gives you four files from one conversion: SVG (web, editing, Cricut/Silhouette), PDF (print-ready, opens anywhere), EPS (the classic Illustrator/print-shop/sign-making format) and DXF (CAD, laser cutting and CNC — contours on per-color layers for multi-pass jobs). No re-uploading or re-converting — pick whichever your workflow needs.
What makes this vectorizer different?
Two things. First, the engine: boundaries between color regions are traced once and shared by both sides (most tools trace each region separately, causing hairline gaps), with sub-pixel edge snapping and automatic gradient detection. Second, honesty: in our open 50-logo benchmark it beats every open-source engine on fidelity — and every job shows you the path count, node count and engine used.
Can I edit the SVG afterwards?
Absolutely — that's the point of vector. Open it in Figma, Illustrator, Inkscape (free) or any vector editor. Our output uses clean cubic Bézier paths with sensible node counts, so editing is pleasant rather than a 10,000-node nightmare.
Is WizVector free?
Yes — 10 vectorizations a day, files up to 4 MB, full downloads with no watermark and no account. Larger files and 2048px high-res output use credits: $9 for 50.
What happens to my images?
They're used only to run your conversion and stored briefly so you can download the SVG. We don't share them or train on them.
