Did you mean gif or webm ? The extension is webm in the commandline

For gif use -vf palettegen and paletteuse to reserve 1 color for
transparency

https://ffmpeg.org/ffmpeg-filters.html#palettegen-1
https://ffmpeg.org/ffmpeg-filters.html#paletteuse

You can combine the two by using -filter_complex, instead of creating a
palette png intermediate

eg.
ffmpeg -r 12 -i toile4-4-%d.png -filter_complex
"palettegen[PG],[0:v][PG]paletteuse" toile4.gif
