Part 1. Why Reduce MP4 File Size?

Why would you want to shrink the MP4 size? The reasons are many. First, you should shorten your video to make it easily shareable on targeted streaming and social media platforms.

On the other hand, minimizing the MP4 file size allows you to store more files on your storage device. In addition, you may want to remove the audio from specific video files. Doing so helps you shrink the MP4 size without any loss of quality.

Large MP4 files can be hard to work with. Their massive size can also temper the viewing experience on certain devices. By reducing a video file’s size, you can make an MP4 file more manageable and shareable while maintaining its dimensions and quality.

Moreover, storing a good chunk of massive MP4 files on a computer can put a strain on system resources, making it difficult to open, view, and edit large files. Editing such files can slow down your system.

Reducing the MP4 file size is a more viable option when compression threatens to endanger the quality of your video. In such situations, minimizing the MP4 file size could help you expedite your workflows and make large video files more shareable and more manageable.

In short, the MP4 file size makes your videos more manageable, easier to store, and more shareable. It helps you make your workflow more efficient, save time in production, and make editing more effortless.

Smaller video files put less strain on your computer resources, allowing for a smoother viewing and editing experience. Smaller files also work better with streaming and social media platforms. Since most internet users view video content on smartphones, smaller video files make your visual content more accessible to a broader online audience.

Part 2. How MP4 Size Compressor Works

An MP4 size compressor reduces the MP4 files using advanced video compression algorithms to shrink the overall file size while retaining as much quality as possible. The tool helps you make your MP4 files easier to upload, share, edit, and store.

A top-class MP4 size compressor online offers a wide range of features like frame rate controls and adjustable bitrate to help you customize compression settings and ensure your audience receives a clear and crisp video experience.

There are two types of compression – lossy and lossless. Lossless compression enables MP4 file size reduction while retaining quality. You use it when you create a ZIP file. Lossy compression, on the other hand, eliminates unnecessary data when shrinking a video file, affecting the video quality.
