Converting files to .gifs?

Hi! I’m making a PMV, and I find the tweening to be really useful, but the “.wick” file won’t let me put it into anything-
Does anyone know what website I could use to convert the .wick to a gif and put it into some editing software (which I’d also appreciate some suggestions)?

I’m new to Wick; exported my first project today as a GIF using Wick’s File > Export Animated GIF (screenshot detail below).
