I use Inkscape to make shapes. Recently I had to use Canva and I must say that even their free plan is impressive in creating social media shares and presentations GIF. I can do almost all they offer in Inkscape, except the animations. They are basic animations that can be added to all the elements of the page in a single click. But I do not know whether there is any software like Blender that can add it locally. If you know one, please do share.
