Vectorise a bitmap into SVG paths
A scanned logo or a hand-drawn icon only exists as pixels; every resize turns it blurry. A threshold pass separates ink from paper and a contour tracer converts each ink region into a closed SVG path that scales forever.

How it works
- Upload a PNG/JPG/BMP with clear ink-vs-paper contrast.
- Tune the threshold if the trace misses thin lines or fills in (default 128).
- Choose outline (stroked) or filled shapes and download the SVG.
Frequently asked questions
Colour images?
They are reduced to greyscale and thresholded into two levels first — this tracer is for line art, logos and silhouettes.
Photos?
Photos produce thousands of noisy contours. Trace graphics, not photographs.
When this tool is not the right choice
You need a hand-editable, layered vector drawing.
Use a desktop tracer (potrace/Inkscape) with colour quantisation.
