A free app for Windows or Mac called LICEcap can help out with this tremendously.
Turn Screen Recordings Into Animated GIFs
First, download the free LICEcap application. Do that by visiting the Cockos Incorporated website and scrolling until you get to the download links for either Windows or OS X.
Once you install the program, launch it to find that it looks like an odd, transparent window. Sure enough, that’s for a reason. Whatever is inside of that window is what LICEcap will capture and turn into an animated GIF.
Before you get started recording, explore some of the options you can edit ahead of time. At the bottom of the window you can edit the pixel dimensions of the recording as well as the maximum FPS, or frames per second. This determines how smoothly the GIF will play back.
Tip: Dragging the corner of the window to resize it will automatically alter the pixel dimensions to the new size of the window.
When you’re ready, click Record… to finalize some settings before the recording begins. In the dialog window you can choose the file name and save location ahead of time as well as other options like displaying the title frame or mouse clicks. You can also have the app automatically stop recording after a certain number of seconds, which you can enable toward the bottom of the window.
When you click Save, LICEcap will automatically begin recording the desired area after a three-second preroll. It’s an odd UI choice, so brace yourself for it to quickly start. Click Pause during if you want to stop briefly or rearrange the position of the window. Otherwise, when the recording is finished, click Stop.
Just like that, in the save location you should see a new animated GIF of exactly what you recorded on screen. Check out the creation courtesy of Guiding Tech’s YouTube channel.
