You asked us, and we delivered! Animated GIFs with transparent backgrounds are now available in our collection of free animated icons.
You can download them in the archive with the rest of the files.
P.S. The edges in transparent GIFs may appear pixelated. It is a feature of this raster format, so bear with us and use GIFs with a white background or Lottie animations when possible.
