About:
Potrace is a tool for transforming bitmaps into vector graphics. It takes a bitmap image (like a PBM, PGM, PPM, or BMP file) as input and produces a variety of vector output formats, including SVG, PDF, EPS, and PostScript. Its primary value is enabling the scaling of pixel-based images to any resolution without quality loss, making it essential for logo conversion and preparing images for print.
Key Features:
  • High-quality tracing algorithm producing smooth curves
  • Supports multiple input and output formats (SVG, PDF, EPS, PS)
  • Command-line interface for automation and scripting
  • Handles both black-and-white and grayscale images
Use Cases:
  • Converting scanned signatures or logos into scalable vector formats
  • Preparing bitmap images for large-format printing
  • Creating clean vector paths from simple line drawings for CAD or design software
Alternatives:
  • autotrace – Similar functionality but Potrace is often cited for superior curve fitting and output quality.
  • ImageMagick (convert) – Primarily a raster manipulation suite with tracing capabilities, but Potrace offers more specialized and refined vectorization.
