Part 1: Why Do I Need to Reduce MP4 File Size?

Reducing the size of an MP4 video file can be beneficial for multiple reasons, including:

1. Save Storage Space

MP4 files can be quite large, especially if they contain high-definition or long-duration videos. Reducing the file size allows you to save storage space on your device or computer, making it easier to manage your video library.

2. Allow for Easier File Uploading & Sharing

Large MP4 files can be challenging to upload or share, especially in cases of slow internet connections or limited file size restrictions on certain platforms. Reducing an MP4 file size makes it more convenient to upload videos to desired platforms and apps.

3. Increase Streaming Power & User Experience

If you want to stream videos online, reducing the MP4 file size can elevate viewers' streaming experience. Smaller file sizes require less bandwidth to transmit, resulting in faster buffering times and smoother playback.

4. Allow for Easier MP4 Video Editing & Processing

If you want to edit or process the MP4 video further, reducing the file size can make the process more efficient. Smaller files require less processing power and can be edited more smoothly. This is particularly helpful when working on slower or less powerful computers.
