Imagetracer is a free and open source (Public Domain) library and application which might be useful to batch convert files. Disclaimer: I made these.

Get ImageTracer.jar from

https://github.com/jankovicsandras/imagetracerjava

and then the basic usage is:

java -jar ImageTracer.jar smiley.png

This can be automated with standard CLI batch processing, for example with bash:

for file in *.png; do java -jar ImageTracer.jar "$file" outfilename "${file/%ext/svg}"; done

This should create SVGs from all PNGs in the current folder.
