Video converter is a tool that changes a video file from one format to another. For example, it can turn a video from a .avia file into a .mp4 file. This is useful because different devices and apps may only support certain formats. By using a video converter, you can ensure that your videos play correctly on various devices, like smartphones, tablets, or computers. The converter often lets you adjust settings like video quality or file size. It’s a handy way to make sure your videos are compatible with whatever you’re using.
