2 Effective Methods to Resize Video on iPhone

Have you ever tried to send a video from your iPhone only to get an error that the file size is too large? Or perhaps you shot a video in portrait mode but need to use it in a widescreen project. Resizing and changing the aspect ratio of videos directly on your iPhone is possible without requiring any extra apps.

In this article, we'll walk you through easy steps to reduce iPhone video file sizes to make them easier to share. Let's get started to learn how to resize videos on iPhone. Then you can get the job done according to your needs.

Part 1. Why We Need to Resize iPhone Videos?

There are several reasons you may want to resize or reduce the file size of videos shot on your iPhone. Here are some of the most common situations to resize video iPhone.

• Social Media Purposes

Most social media platforms like Facebook, Instagram, and Twitter place limits on the maximum size of videos you can upload. iPhone videos shot at the highest 4K resolution are often too large to directly upload. Resizing brings them under the size limit so they can be posted.

• Faster Sharing

Large video files take longer to upload and share. By making an iPhone video smaller through resizing, transfers will be much quicker whether sharing through email, messaging apps or placing in cloud storage.

• Storage Space

Video can quickly eat up storage space on your iPhone. Making videos smaller allows you to free up local storage room for more videos, photos, apps and more.

• Aspect Ratio Mismatch

Sometimes iPhone videos are shot vertically but need to be used in widescreen projects and vice versa. Changing the aspect ratio allows better fitting without black bars or cropping parts of the video out.

• Prepare for Specific Projects

Video editors often desire footage to have specific frame sizes and dimensions. Resizing iPhone videos beforehand makes it quicker to start editing them in projects.

Part 2. Resize iPhone Videos by Reducing Video File Size

The file size of a video determines how easy it is to share and store. Larger video files take up more storage space on your iPhone and are harder to upload online. Many popular sharing platforms and social media sites place strict limits on the maximum file size for video uploads. For example, some common video size restrictions are:

• Facebook: 4GB max
• Instagram: 4GB max, 60 sec max length
• Twitter: 512MB max
• WhatsApp: 16MB max
• Gmail attachment limit: 25MB
• iCloud free storage: 5GB total space

If an iPhone video exceeds these size limits, you won't be able to directly upload or attach it. Trying to share videos that are too large will result in frustrating error messages. Additionally, oversized videos eat up precious storage on your iPhone.

That's why it's useful to be able to compress and reduce size video iPhone to make them smaller. Reducing video file sizes before sharing allows you to post clips anywhere and frees up local storage room on your device. Understanding typical video size restrictions helps motivate the need to shrink down iPhone videos when necessary.
