GIFExplainer has some handy tools in it that can save you even more time:
- Screenshot capture with options to capture a rectangle with specified size (say, to match slide size), capture active window or freeform region.
- HTML wrapper generator that helps you to embed explainers in your HTML pages. It allows to run GIF explainer on mouse click to reduce page load time.
- HTML Bootstrap UI framework carousel generator to use in case you do not want to embed a GIF into your webpage but OK to go with an image slideshow instead.
