EdgeSVG vs Scan2CAD

EdgeSVG converts raster images into SVG vector graphics using an open-source vectorization engine. Its automatic mode categorizes an image as a logo, icon, illustration, or photo, then selects a tracing approach. Other documented modes include convert, logo, premium, auto, smart, and optimal; smart mode searches iteratively within SSIM and file-size constraints. Output scoring covers similarity, edge alignment, foreground overlap, topology, file size, and path counts. The project offers Rust, Python, Node.js, command-line, and WebAssembly interfaces under a shared response contract. Its WebAssembly engine runs in the browser without a server or uploads, according to the maker. Batch processing handles directories and can produce JSON and Markdown reports with per-image scores and summaries. CI/CD examples cover GitHub Actions, GitLab CI, Docker, and pre-commit hooks. EdgeSVG is free and published under the Apache 2.0 license, with Linux, macOS, Windows, and web support. It is neither a hosted API nor a GUI design tool.
