What ImageTracerJS is

ImageTracerJS is a JavaScript tool for tracing raster images into SVG vector output. It can run in a browser: load the JavaScript file and call its tracing functions. For Node.js, the project includes a command-line interface that converts an image to SVG. Its API can provide either an SVG string or tracedata, with asynchronous functions for browser use and synchronous ImageData functions for browsers and Node.js.

Tracing behavior can be set with an options object or chosen from presets, including posterized, grayscale, detailed, and artistic variants. The CLI supports almost all options, with pal and layercontainerid as exceptions. For Node.js image loading, an external library is required because Node.js does not include canvas and DOM support. ImageTracer is also available as an Inkscape extension. The project is free and uses the Unlicense, which permits commercial and non-commercial use, modification, and distribution. The license provides the software as-is without warranty. The GitHub profile identifies András Jankovics as the account holder.

Who it suits

ImageTracerJS suits developers who want JavaScript-based raster-to-SVG tracing in browser projects or Node.js workflows. It can also suit people using Inkscape, or users who need a license that permits modification and commercial or non-commercial distribution.

What it does well

  • Converts raster images into SVG vector output.
  • Provides both browser use and a Node.js command-line interface.
  • API can return SVG strings or tracedata.
  • Offers tracing options and posterized, grayscale, detailed, and artistic presets.
  • Unlicense permits commercial and non-commercial use, modification, and distribution.

What to know first

  • Node.js image loading requires an external library.
  • The CLI does not support the pal and layercontainerid options.
  • The Unlicense provides the software as-is without warranty.

Limits

The CLI omits support for pal and layercontainerid. Node.js image loading requires an external library; the license also provides the software without warranty.

As github.com lists them, read 9 Oct 2026. The maker's own page has the final word.

Getting started

  1. For browser use, load the JavaScript file and call its tracing functions.
  2. For Node.js conversion, use the included command-line interface.
  3. Provide an external library for image loading in Node.js.
  4. Set tracing options with an options object or choose a preset.
  5. Use the API to retrieve an SVG string or tracedata.

Verdict

Choose ImageTracerJS if you need a free JavaScript raster-to-SVG tracer with browser and Node.js options, adjustable tracing, or Inkscape availability. Look elsewhere if your Node.js workflow needs built-in image loading or your command-line use depends on pal or layercontainerid.

Questions

What does ImageTracerJS produce?

It traces raster images into SVG vector output.

Can I use it in a browser and in Node.js?

Yes. Browser use is documented, and the project includes a Node.js command-line interface. Its API also provides functions for browsers and Node.js.

Is ImageTracerJS free, and can it be used commercially?

It is free and uses the Unlicense, which permits commercial and non-commercial use, modification, and distribution.

Does the Node.js CLI support every option?

It supports almost all options, except pal and layercontainerid.

Does Node.js image loading work without an extra library?

No. The README says Node.js image loading requires an external library because Node.js lacks built-in canvas and DOM support.

Who is identified as the maker?

The GitHub profile identifies the account holder as András Jankovics.
