Vectorization.org vs WinTopo

Vectorization.org is a web service that converts raster images into scalable vector files. It accepts JPG, PNG, PDF, and JPEG uploads and can produce SVG, EPS, PS, PDF, or DXF files. To use it, choose an output format, upload an image, and save the resulting file; registration is not required. The free plan is listed at free. Uploads are limited to 10 MB, with image dimensions capped at 3000 × 3000 pixels. Tracing is monochrome, so color images become black and white, and batch conversion is unavailable. The site identifies Potrace from Peter Selinger as its background autotracer. Submitted inputs and outputs are automatically deleted after half an hour, with no backups. The service runs on the web and is identified as a service of Spikerog SAS in Laure Minervois, France.

WinTopo is Windows desktop software that converts TIF, JPG, PNG, GIF, BMP files, and scanned images into vector files for CAD, GIS, and CNC applications. One-Touch Vectorisation performs raster-to-vector conversion in a single click. Documented exports include DXF, SHP, PDF, MIF, ARC, DI, WMF, EMF, ASC, and WTX, and batch conversion is available. WinTopo Pro adds image processing, more advanced vectorisation algorithms and options, georeferencing, GeoTIFF coordinate extraction, and manual vector digitising over the raster image. Its trial includes all Pro features, but an unlicensed copy saves only a sample of the vector result. Freeware is unrestricted for small conversion volumes. The first Pro license costs 200.00 GBP once for one computer; an additional license costs 150.00 GBP once. WinTopo generally runs on Windows 7 or higher, with stated approximate minimums of a 1GHz CPU, 0.5GB memory, and 50MB storage.
