A static image or a file whose frames are all identical is not treated as an animation.
GIF delays use 10ms units, and this tool saves very short delays at a minimum of 20ms. Small timing differences can result.
The selected background fills transparent areas. Inspect edges against that color.
Tool files and calculation inputs are processed in your browser, without uploading them to a processing server.
