AutoTrace vs Vecto

AutoTrace converts bitmap images into vector graphics, with tracing options for outlines or centerlines. It can reduce colors and despeckle images to reduce noise, and its listed maximum color count is 256. Input formats include PNG, BMP, TGA, PNM, and GF; ImageMagick or GraphicsMagick can add JPEG, TIFF, GIF, and other formats. Outputs include SVG, EPS, PDF, AI, DXF, CGM, EMF, MIF, ER, and Fig. The project documents command-line conversion and use through the libautotrace library. It is free and listed for Linux, macOS, and Windows. Installation options include package managers for macOS, Linux, and FreeBSD, Windows installers, or building from source. Source builds require a C compiler and GLib 2.58 or newer; libpng and ImageMagick or GraphicsMagick are optional dependencies. The program is licensed under GPL v2 or later, while the library uses LGPL v2.1 or later. The README directs users to the issue tracker and describes the graphical frontend as inactive. Version 0.31.10 is listed as the latest release.

Vecto converts raster images such as logos, icons, illustrations, scans, and photos into editable SVG files. It accepts PNG, JPG, BMP, and GIF, preserves transparency, and provides a live side-by-side preview with synced zoom. Its tracer builds a connected mosaic, fitting shared boundaries once to avoid gaps or overlaps; it can represent straight edges as true lines and circles as exact arcs. Sub-pixel placement positions boundaries between pixels rather than snapping them to the pixel grid. Users can export SVGs or copy them to the clipboard for design and cutting software. Photo tracing can create stylized posterized vector art with a chosen number of colors. The maker says processing happens locally, images are not uploaded, and the app works offline without an account. Vecto is MIT-licensed and available free to download or build. The graphical application is Windows-only; Linux and macOS downloads are command-line tools for tracing, batch jobs, and benchmarking. A Microsoft Store version costs $7.99, paid once.
