ImageTracerJS vs Vectorizer.AI

ImageTracerJS is a JavaScript raster-image tracer that converts image data into SVG vector output. It can run in a browser by loading its JavaScript file and calling tracing functions, or in Node.js through a command-line interface. Its API returns SVG strings or tracedata for further processing. Browser-only asynchronous functions and synchronous ImageData functions are available for browsers and Node.js. Tracing can be configured through an options object or presets, including posterized, grayscale, detailed, and artistic variants. Controls cover line and spline error thresholds, path omission, corner enhancement, color sampling, palette size, layering, SVG rendering, and blur preprocessing. The command-line interface supports nearly all options, with pal and layercontainerid as exceptions. Node.js image loading requires an external library because Node.js lacks built-in canvas and DOM support. The project is also available as an Inkscape extension. ImageTracerJS is free under the Unlicense, which permits use, modification, and distribution for commercial or non-commercial purposes, with no warranty. The project notes that large images or many layers can trigger out-of-memory errors and that error handling is limited.

Vectorizer.AI turns raster images into editable vector graphics for uses including logos, illustrations, print, web, CAD, and CNC. It accepts PNG, JPG, GIF, BMP, and WebP files, and can export SVG, EPS, DXF, PDF, or a cleaned-up PNG. Its conversion process pairs in-house deep-learning models trained on a proprietary dataset with geometric methods for shape fitting, corner cleanup, and symmetry modeling. Users can upload, convert, and preview images without commitment; production results from example images are available to download free. Web App uploads are capped at 3 megapixels and 30 megabytes, with cropping to fit the resolution limit. Developers can connect through SDKs, a CLI, HTTP endpoints, or OpenAPI. API access starts at $9.99 a month for 50 credits, with one credit covering one image; the Web App is $9.99 a month and has no API access. Unused API credits roll over up to five times the monthly allowance. The product is available on web, Linux, macOS, and Windows.
