Potrace can currently produce the following output formats: EPS, PostScript, PDF, SVG (scalable vector graphics), DXF, GeoJSON, PGM (for easy antialiasing of pixel-based images), Gimppath, and XFig. Additional backends might be added in the future.
A separate program, mkbitmap, is also provided. This program can act as a pre-processor for Potrace, applying scaling and various filters to an image before converting it to a bitmap. This is useful for potracing greyscale and color images.
