How to Reduce MP4 File Size without Visual Quality Loss

MP4 is the most common used video format all around the world at present. However, as MP4 videos are used in a large scale, users also find problems about video size. MP4 videos will take up the most storage space of devices. Moreover, it consumes too much time to upload them to trendy social media sites. Also, emailing MP4 video is not accessible if its size is bigger than the maximum required. Then how to reduce MP4 file size? After reviewing some video compressing software, we figure out two ways to shrink MP4.

Why we have to make MP4 video smaller?

Before we introduce the way to compress MP4, first let’s explore the reasons to do that in details.

  • For storage.

Nowadays people use different types of camera to shoot MP4 video, and its quality is getting increasingly better. As a result, the size of MP4 file is bigger and bigger as well. For example, a one-minute MP4 video (1080P, 60fps) shot by iPhone 12 can be 175MB. HD MP4 can be such size, let alone 4K MP4. But, commonly people will shoot videos that are far more than one minute. Therefore, to save storage space of your devices, compressing MP4 file is a better choice.

  • For uploading.

Uploading videos to social media sites is what most of the users will do, but these platforms all have required the max video size. First, if your MP4 file is oversized, it cannot be uploaded. Second, even when the video size is within the limitation, uploading large MP4 file to them can be time-consuming. What’s worse, the process may be interrupted by error. In this way, for smooth uploading and sharing your video, you would better get the MP4 file downsizes.

  • For email.

In daily life we also have the need to sending videos via email now and then, and many them are not from websites, so it’s not possible to just simply provide the link of the video in email. Video size is not unlimited as well for email. It’s better to reduce video size for sending email.
