Compressing a video not only frees up space of the computer, since from time to time you must have the need to share interesting videos with other, either via YouTube, Facebook or Email, like you do with funny photos. But not as lucky as photos, videos will take up much more rooms. Let's turn the rocket science into an easy task with free WinX Video Converter, which can compress a wide range of videos to the file size you'll need for different uses, up to 70% compression rate! At the same time, the image quality won't get drowned.
The following text will show you how to free reduce a video on Windows PC or compress a video on Mac (iMac/MacBook/Mac Pro), respectively. Before that, please download the proper edition of the program by clicking the corresponding download button right below.
WinX Video Converter will help you free convert video formats (e.g.: MKV to MP4, H.265 to H.264, MTS to AVC), change video resolutions, or turn the video definition, for example, from 4K 2160p to HD 1080p/720p so as to reduce videos successfully and speedily.

After downloading the Windows version of the top free video compressor software, please launch it and get it ready. You'll be shown on compressing a video to a great degree in just 6 steps.
Step 1. Add a video file.
Click the Plus Video button on the top left of the interface. Browse through your computer, click on the video you need to compress, and hit Open button to add the video source from your Windows (10) PC. WinX Video Converter allows you to add more than one video at a time for batch compression.
Step 2. Convert the video format.
Choose a desired output format among what are listed in Output Profile Category. Optionally, change the quality bar to LQ (Low Quality) if you don't mind much on the image effect.
(Note: 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.)
Step 3. Edit video resolution and so on.
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.
Step 4. Disable the subtitle track and avoid multiple audio tracks.
If the movie or video has multiple subtitle tracks in the language you can actually understand, there is no need to use the subtitle. So, choose "Subtitle Disabled" in the Subtitle option. Reduce the audio tracks as many as you can in the Sound item.
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.
Step 6. Click "RUN" to start.
Do not choose "Use High Quality Engine" or "Deinterlacing" option if you need your HD video better compressed. Uncheck "Safe Mode" button and choose a higher CPU Core Use if you want a faster conversion process. Then click "RUN" button and start the conversion and compression at the same time.
"I end up with finding no good video compressor on Mac for shrinking videos for iMovie, Email and so on, since the output video image is always not as expected. Is there any freeware to compress a video on Mac easily?"
Shrinking a video on Mac OS using WinX Video Converter for Mac (free & clean) has much in common with that on Windows.
Step 1. Import video file.
Add one or more (HD/4K) video file to be compressed from your Mac by clicking "+" button.
