However, what’s the point of having a phone that can take quality videos, but makes it almost impossible to share with others because it’s too large to be uploaded on a website or social media? Well, you shouldn’t be bothered just yet. There are ways to declutter your mobile storage, and knowing how to compress a video on iPhone is one sure method.   If you want to learn how to work your way around video size reduction on an iPhone, you’re at the right spot.

Steps to Decrease a Video’s Size

Since Apple is constantly utilizing the latest technology to improve the video capabilities of their devices, which in turn improves the video quality of users.

Hence the need to learn these steps. Here are a few steps to reducing a video’s size.

Let’s begin in earnest. 

Use Video Compress

Unarguably one of the best apps for decreasing a video’s size, video compress is the number one go-to app for users with cramped phone memory. 

What makes this app stand out is that it’s free. Though, it has some in-app purchases that cost about $2.00 for upgraded features that allows you to cut down a video’s size without limit.

Here’s how to compress a video on iPhone with video compress. 

  • Download the app from the iOS store and begin the installation process.  
  • Once the installation process is complete and you open the app, you’ll be greeted with a big ‘+’ icon.  
  • As expected, the app will request administrative permission. Tap Ok, and then proceed to select from a catalog of videos. 

If you want to speed up the process, you can long-press a video for two seconds, then tap on other videos for a collective size reduction. 

  • The next step is to choose from an array of options to determine the resulting video quality. 

Depending on how badly you need to make room on your device, you 

can decide to select Full HD with minimal alteration to your video quality or 360P for a slight video clarity decrease. 

But wait, 

What if this reduces my video resolution to an old 90s brick game, you might ask?

Okay, chill for a moment. 

You’re using an iPhone, and every iOS app in the apple store is built to give a stellar performance. So even though you select the lowest resolution possible, your video would still come out looking crisp and Instagram-worthy. 

  • After your resolution selection, select the folder you want to save your new video into and click ‘add new album.’ 
  • The compression process should begin once you’ve selected a folder, and depending on the size and number of videos chosen, the process can take anything from 30 seconds to a few minutes. 
  • Upon complete execution, you’ll receive a notification asking whether to retain the original video. And your response to this should be, ‘out with the old in with the new.’
