(Note: Compressing 4K to 1080p video and converting a video from one format to another may reduce the file size, since different video format containing different video Codecs may use different compression techniques. The free video compressor supports a large variety of video formats, be it for inputting or outputting. Especially, various output profiles are built in the software such that users can choose directly. Specifically, it has device profiles for Apple (iPhone/iPad/Apple TV/iTunes), Android, Microsoft, Sony, BlackBerry and Nokia, web video profiles for YouTube, Facebook, Vimeo, as well as PC and Mac general videos. For regular use, we recommend MP4 format.)

Click the gear-wheel-shaped icon, and go to the "Edit" state:
1. You can change "Resolution" from Keep origin to a lower one. For example, 640x480 is a standard definition that is the most common video resolution for YouTube, Facebook, iPhone, iPad, Android, Windows Phone and the like;
2. You can cut "Frame Rate" from generally 30/29.97 fps to 23.97 or 25;
3. Bit rate, sample rate for audio can be set lower to get a smaller size.

Note: The "Subtitle" feature also enables you to add Extra subtitle (.srt) files downloaded from the internet.

Step 5. Reduce time length of the video optionally.
Click the scissors icon and enter the detailed setting Window. Tap "Trim" button, check "Enable Trim" and cut down the unwanted part of the video, which is also a feasible way to reduce the large video size.
