A MOV file is a video file format that can hold video, audio, and text in one file. It is an MPEG4 file developed by Apple and is mainly used with Apple's QuickTime software. As one of the most common video formats, video editors often favor a MOV format because it supports high-quality videos. However, a high-quality video can also mean a large file size, so xTRIGGER092x from the Apple Support Community raised this question:

I have a monster 4GB folder full of .MOV files shot on an iPhone that I need to compress small enough to fit on two or three 700MB discs - or a 2GB flash drive. However, I don't really know how to do it. Is it possible to compress in iMovie (and if so, how), or will I need freeware? Or is it even possible at all?

Thus, we need to compress MOV files. There are several reasons you would want to compress your .mov file on Windows and Mac; it could be to free up space in your storage device, to send the file easily as an email attachment, easy upload on your socials, or simply for smooth playback.
