How to Compress a Video and Reduce the File Size

Need to compress a video? Here's how you reduce your video size on any operating system.

Has your video turned out to be too large? More often than not, that’s the case these days. Fortunately, there are various tools and methods you can use to compress videos and reduce video file size.

Here we show how to compress a video on Windows, Mac, iPhone, and Android.

How to Compress a Video on Windows

You don't need to know how file compression works to compress video on Windows 10. There are multiple ways how to compress a video file on Windows. Here are three of those ways.

1. Compress a Video by Zipping It

ZIP archives help you compress and combine your files. You can create a file archive (such as a ZIP or 7Zip archive) for your video, which is a great way to reduce video size on Windows 10.

Here’s how you do that:

1. To compress multiple videos, put them all in a single folder on your PC.
2. Open that folder, select all the videos you want to compress, right-click on any one video, and select Send to > Compressed (zipped) folder.
3. Windows will create a new archive and save it in the same folder as your videos.

The size of this archive containing your videos will be significantly smaller than the size of your original videos. This works on most standard file types, such as if you wanted to compress MP4 files on Windows 10.

Want to do it with a single video? Start at step 2 in the above list, using the single video you want to compress.

2. Compress Your Video Size Smaller Using the Built-In Video Editor
