What is ImageTracer?

Also known as: ImageTracer.js

A JavaScript open-source raster-to-vector library. Specializes in line art and high-contrast images. Widely used in browser-based vectorization tools.

In detail

ImageTracer is a pure-JavaScript vectorization library suitable for browser execution. Its strengths: line-art tracing, high-contrast images, simple line drawings. Configurable parameters include color count (default 8), edge smoothness, line precision, and the 'ignoreWhite' flag (treat white as transparent — essential for tracing motifs on white backgrounds). Compared to VTracer, ImageTracer is slower on color images but produces cleaner output for monochrome line art, runs entirely in-browser without server cost, and has been ported to many languages. Texloom Studio uses ImageTracer for the in-browser Vectorize Studio free tool.

Example

A hand-sketched line drawing of a leaf, scanned at 300 DPI, traces via ImageTracer with ignoreWhite=true and color count=2 into a single black SVG path of 24 Bezier curves. Total processing: 800ms in the browser. Output drops cleanly into Illustrator for further refinement.
