A screenshot shows a state. A GIF shows a motion. An interactive demo shows a procedure the viewer performs. They get mixed up because all three start as a picture of a screen, and because the habit of one team becomes the default for every job.
Best for: one state, one point, read at a glance. A setting, an error, a result, a design detail. Cheapest to make, easiest to annotate, universally supported. Fails when the point is a sequence. Demorta’s screenshot tool makes them from the browser with an editor attached. Try the free screenshot tool.
Best for: a short motion that a still cannot show -- an animation, a drag, a transition, a bug that only appears mid-movement. A few seconds, looping, no sound. Fails when it is long: file sizes balloon, the loop restarts before the viewer has caught up, and nothing can be paused or clicked.
Best for: a procedure of several steps the viewer needs to understand or perform. They click through the real screens at their own pace; each step has its own caption; you see which step they stopped on. Fails as a single frame -- a demo of one screen is a screenshot with a Next button. Demorta records these from the same extension.
