Part 1: Compress a Video on iPhone Directly

A direct compression in your iPhone is a perfect service for anyone who struggles in insufficient storage because this process doesn't need any third-party tools. All you need to do is to open your iMovie application on your iPhone, read this guide, and execute the stated procedures.

Compressing video on an iPhone in iMovie is an easy way to reduce its file size, thus facilitating the option to share it easily or take less space on your device. iMovie is a pre-installed app created by Apple for iOS devices. Therefore, it is hassle-free and an access tool for iOS users who require editing and conversion processes. Whether trimming, adding some sweet effects, or just resizing the video, it does it all conveniently for a quick adjustment. Follow this guide below, hit a few buttons, and enjoy your newly compressed video.

Step 1Open the iMovie app from your iPhone and tap on Create Project. Then select the video that you want to compress from your images and tap Create Movie.

Step 2Now, the video is open in the editing timeline. Tap Done at the upper left to return to the project screen. Then tap Share on the lower part of the display, marked by a square with an arrow pointing up.

Step 3To choose the resolution and quality, tap Save Video and the resolution option, such as 1080p, 720p, or 540p. The smaller the resolution, the less the video's file size will consume.

Step 4Finally, iMovie will compress the video and keep it in Photos so you can share it easily or store it more manageably.

Part 2: Compress iPhone Video While Maintaining High Quality

This typically consists of compressing video files on your iPhone to an extremely compact size without losing quality. Sometimes, compressing will reduce the video's sharpness or clearness, and that's the compromise: size vs. quality. Better results can be achieved using a dedicated tool to compress videos, such as AVAide Video Converter. With AVAide, you can compress video files so they can fit into your storage or allow you to share them before a real loss in quality.

The AVAide Video Converter is a useful app for people who want to compress video from an iPhone without sacrificing quality. It uses customized compression settings to support various video formats like MP4, MOV, and AVI. However, this software is not readily available on mobile devices, so you must use a laptop or PC.

Step 2Choose Your Video

Step 3Select Compression Settings
Next, go to the Custom Profile, which allows you to set the Resolution, Format, and Bitrate for the desired video quality. For instance, reducing the resolution from 1080p to 720p will decrease the file size. However, finding a balance between a smaller file and maintaining video quality should be in your best interest.

Step 4Start Compression
After adjusting the settings, click Compress to initiate the process. AVAide uses advanced algorithms to maintain the video's visual quality even at smaller file sizes. After compression, transfer the video to your iPhone using iTunes or a file-sharing app.
