What PathSmith is
PathSmith is a free, open-source Rust toolkit for turning raster images into SVG files and producing multiple crops from one image. Its Vectorize tool offers several tracing pipelines, with outputs available for side-by-side comparison. Multicrop lets users define multiple boxes and export each crop, trimming boxes that extend beyond the image. The web app accepts PNG, JPEG, WebP, GIF, and BMP files. PathSmith is available as a web app, HTTP API, CLI, Docker container, WASM/npm package, and Rust library. The CLI and WASM build currently handle Vectorize only; the HTTP API and Rust library support both Vectorize and Multicrop. The maker says images stay on the user's machine unless they choose to upload them elsewhere, and the WASM version can vectorize in the browser without an upload. Documentation lists a default 20 MiB upload limit, up to 64 in-flight conversions, and a 60-second request timeout. The AGPL-3.0-or-later license applies; commercial licensing is available on request.
Good
- Free and open source.
- Compares multiple tracing pipelines side by side.
- Supports batch conversion.
- Offers an API, CLI, and library.
Watch out
- CLI and WASM support Vectorize only.
- Default upload limit is 20 MiB.
- Requests have a 60-second timeout.
- Commercial licensing is available on request.
Who it suits
It suits people who need raster-to-SVG conversion or multiple crops, including developers integrating image workflows through the API or Rust library. Users who want to keep vectorization in the browser can use the WASM version.
Verdict
PathSmith offers vectorization and multicrop across several deployment options, though available workflows vary by surface. Check its documented limits and license requirements before choosing an implementation.
