Compress videos on iPhone

For most of us, the photos and videos take up the most storage on our iPhone. We want to take photos with the highest level of image quality but at the same time we want to save our precious storage. Apple pushed towards a solution with compression and quality in mind in iOS 11, the two new formats for photo and video, HEIF and HEVC. In this article, we will discuss how you can reduce video size and compress videos on iPhone X, 8, 8 Plus and earlier iPhone models.

Record HEVC/H.265 videos on iPhone X, 8, 8 Plus

If you are using the latest iPhone model, you should take advantage of the new video standard, HEVC/H.265, which can help you save up to 50% storage space. Go to Settings >> Camera >> Formats, and ensure the “High Efficiency” option is selected. Compared to H.264/AVC, the new video codec can encode higher quality video with better compression rates. Try to record a video in the same resolution and length, you will find the H.265 (HEVC) video is about half the size of the H.264 video.

Change iPhone video resolution

The higher the resolution and frame rate, the more space the video will take up on your iPhone. You can change your iPhone video resolution settings to tell the camera to shoot video clips in smaller resolution or size. For example, if you are using an iPhone 8, go to Settings > Camera > Record Video to change the video resolution. You can choose from 720p HD at 30fps, 1080p HD at 30fps (default resolution), 1080p HD at 60fps, 4K at 24fps, 4K at 30fps, 4K at 60fps. And go to Settings > Camera > Record Slo-mo to change it to either 1080p HD at 120 fps or 1080p HD at 240 fps.

For existing videos saved in your Camera roll, you can use a video editor to change video resolution and size on iPhone.

Compress videos using a video editor compressor app

This is the most efficient way to batch compress large videos. We recommend Video Slimmer for this task. It can compress videos through lowering the video quality and resolution. Unlike the H. 264 to H.265 upgrade, you can reduce file size without losing quality or resolution. If you want a smaller file size using this video compressor app, you have to sacrifice quality or resolution. Video compression can be done in three steps. Go to import source video from your Camera roll to the video compressor app. You can add multiple video clips and batch compress them at the same time. Then choose Video Quality and Video Size, then compress. See the following step-by-step guide to compress videos to email on iPhone.

This method works with not only the recent iOS devices, but also earlier models, such as iPhone 7, iPhone 6, iPhone 5, etc.

Convert H.264/AVC videos to HEVC/H.265

If you are using an earlier iPhone model or iOS version, you can also convert the traditional H.264/AVC videos to HEVC/H.265 which would result in smaller files, then download a third-party video player with the HEVC/H.265 decode support to play them on your iOS device. We recommend this desktop video converter program and you can follow these steps to convert videos to HEVC/H.265 on your computer.
