Step 2. Set the compression rate by clicking the “Compress all file sizes to” button. This will apply to all added videos. You can also click the gear button next to each single video. This way, you can set file size, resolution, and bitrate separately.

Step 3. Click “Compress All” and it will start compressing. After it finishes, you can click “Download All” or the arrow-down button to save the compressed videos to your device.

Method 2. How to Compress MP4 Videos via Media Player

Some media players can also be used to compress MP4 files. VLC media player is one of these versatile players. It is known as an open-source media player for its versatility and compatibility. You can use it to play any audio or video format. Also, you can utilize this tool to compress MP4 videos on Windows or macOS. As for video compression, you can reduce the file size by changing encoding parameters such as video, and audio codecs.

Step 1. Download, install, and launch the VLC media player from its official site, click the “Media” menu, select “Convert/Save”, and click the “Add” button to upload the MP4 video. Then, confirm your uploads by hitting the “Convert/Save” at the bottom.

Step 2. A new window will pop up to guide you through output settings. Navigate to “Profile“, select the output resolution from its dropdown menu, and click the spanner icon next to it to set other settings like video, and audio codecs.

Step 3. Select a file path by browsing the “Destination file“. Then, click the “Start” button to start MP4 compression.

The process is quite simple. However, VLC lacks advanced customization options and can only provide basic compressing features. Also, since VLC reduces the size by re-encoding, it will lead to lower quality for the compressed videos. For those having a higher requirement, a professional compressor, like Media.io Video Compressor, can offer superior performance.

Method 3. How to Compress MP4 Files via Video Transcoder

A video transcoder is also a powerful tool for compressing MP4 files. It usually delivers the optimal compression by re-encoding the video with more efficient codecs. It also allows you to adjust parameters like bitrate, resolution, and frame rate.

HandBrake is a staple among so many choices. You can use this open-source application on Windows, macOS, or Linux. It also offers a wide range of customization options. You can fine-tune videos to balance file size and video quality. However, the interface of HandBrake is not straightforward enough, therefore, beginners might find it hard to get started.

Step 1. Download, install, and launch HandBrake on your device. Click “File > Open Source“, and a new window will pop up to guide you to upload the MP4 video.

Step 2. You will have a screen to customize the compression parameters. First, go to the “Dimensions” tab to select a “Resolution Limit” lower than the source video. Then, go to the “Video” tab to lower the “Constant Quality“. For a detailed explanation of more options, you can hover your mouse pointer over the option.

Step 3. After setting up, you can click the green “Start Encode” button on the top to compress MP4 video.

Conclusion

Compressing MP4 videos without quality loss can be easy with a proper tool. For tech-savvy users with extensive knowledge of video encoding, video transcoders like HandBrake offer powerful options.
