How we judge a vector file

Any tracer can output an SVG. What matters is whether the file saves you work once you open it. These are the things we check when we improve our models, and the things worth checking on your own files.

Edges and shapes

Corners should stay sharp and curves smooth, at any zoom. We compare the trace with the original at high magnification, where pixel staircases and lumpy curves show up.

Colors

Each color in the image should come back once, without extra in-between shades from soft edges. Smooth blends should stay smooth, as gradients rather than stripes.

Structure

One path per color, a sensible number of anchor points, and a file size in proportion to the detail. A flat logo should be a small, light file.

Small details

Thin lines, small text and the gaps inside letters are the first things to break. They should be complete and open.

Check it yourself

On the home page, the vector inspector lets you switch on outlines and anchor points and zoom in on real results. The same compare view appears after every conversion.

What we do not claim

No tracer gets every image right. Photos, tiny images and fine textures are hard for any of them, and some brand work is still worth redrawing by hand.
