This one needs a warning before anything else: tracing is approximate, and it is the only conversion on this site that is. Every other tool here reproduces your image faithfully. This one looks at a grid of pixels, guesses where the shapes are, and draws new paths around them. The output resembles the input. It does not reproduce it.
Why a real conversion is impossible
A PNG contains no shapes. It contains coloured pixels, and whatever curves and strokes the designer originally drew were thrown away the moment the file was exported. Tracing is reconstruction from evidence, not decoding. When a tool claims to convert a bitmap to vector, this is what it is doing, however it is described.
What traces well
- Flat logos with a handful of solid colours and clean edges. This is the case tracing was designed for and it works genuinely well.
- Black-and-white line art, signatures, stamps and simple diagrams.
- Icons, silhouettes and bold lettering, especially at higher resolutions.
- Screenshots of simple shapes, though text usually comes out lumpy.
What does not
Photographs. A traced photograph becomes thousands of overlapping coloured blobs — a file many times larger than the original that looks like a bad watercolour of it. There is no setting that fixes this, because the problem is conceptual: photographs have no shape boundaries to find. Anything with gradients, soft shadows, blur or fine texture has the same problem to a lesser degree.
JPEG artifacts are a related trap. If your source has been compressed hard, the tracer faithfully finds the edges of the compression blocks and turns each one into a path. Starting from the cleanest version you have makes a visible difference.
Treat the output as a starting point
Open the result in Inkscape, Illustrator or Figma and expect to do some work. Traced paths carry far more anchor points than a human would draw, curves are approximated by many short segments, and colours are quantised into flat bands. For a logo you are recovering because the original file is lost, that is a reasonable trade. For anything else, redrawing from scratch is usually faster and always cleaner.
Large images are scaled down before tracing, because cost climbs steeply with pixel count and a bigger input mostly produces a bigger file rather than a better one. Tracing runs in a background thread on your own device, so the page stays responsive and nothing is uploaded.
