PathSmith

What PathSmith is

PathSmith is a free, open-source Rust image toolkit for converting raster images into SVG files and producing multiple crops from one image. Its Vectorize feature provides several tracing pipelines, allowing users to compare SVG outputs side by side. With Multicrop, users mark several boxes on an image and export each crop; boxes crossing the image boundary are trimmed. The web app accepts PNG, JPEG, WebP, GIF, and BMP images, and batch conversion is supported. The maker describes processing as in-memory and parallel. PathSmith is available as a web app, HTTP API, CLI, Docker container, WASM/npm package, and Rust library. The CLI and WASM build support Vectorize, while the HTTP API and Rust library support both Vectorize and Multicrop. The API can script conversion and cropping or connect those operations to other applications. The maker says images remain on the user's machine unless they choose to upload them; WASM can vectorize in the browser without uploading. Default repository limits are a 20 MiB upload size, 64 in-flight conversions, and a 60-second request timeout. PathSmith uses the AGPL-3.0-or-later license, with commercial licensing available on request.

Who it suits

PathSmith suits people who need to convert raster images into SVG or prepare several crops from one image. It also fits developers who want an HTTP API, CLI, Rust library, Docker container, or browser-based WASM option for image workflows.

Limits

The repository documentation gives defaults of 20 MiB maximum upload size, 64 in-flight conversions, and a 60-second per-request timeout. CLI and WASM currently support Vectorize only; the HTTP API and Rust library support both Vectorize and Multicrop.

Getting started

1. Open the PathSmith web app at https://pathsmith.avarnic.com/.
2. Choose Vectorize for SVG conversion or Multicrop to mark crop boxes.
3. Use PNG, JPEG, WebP, GIF, or BMP images in the web app.
4. For programmatic use, select the HTTP API, CLI, Docker container, WASM/npm package, or Rust library.

Verdict

Choose PathSmith for free raster-to-SVG conversion or multi-cropping, particularly if comparing tracing outputs or using its API and Rust library matters. Look elsewhere if you need Multicrop through the CLI or WASM build; those surfaces currently support Vectorize only.
