Gif Convert
I made this tool to make it much easier to create gifs from a set of png images.
You simply import individual images or select a folder and then choose your options like framerate and scale and click save to generate a nice gif.
You can view the source code aswell as install/usage instructions on Github.
One caveat for macOS Catalina and above is that the bundled python3 will not work because it lacks tcl/tk support, you will need to download and install python from python.org.
