In this tutorial, you will be shown how to enable iOS 11 HEVC / HEIF feature for photos & videos on your iPhone and ipad. Apple just introduced this HEIF / HEVC feature in its latest iOS 11 operating system that stores images and videos in compressed form to save storage space on an iPhone and iPad. This feature will be extremely useful on iOS devices with low internal storage, and for those who take loads of photos or like to record HD videos with their iOS mobile devices.
Content created in these two new HEVC / HEIF formats takes up around 50 percent or less space than the previous formats used by Apple on its iPhone and iPad. Moreover, you can enable and disable both formats as you please. By default, this format is disabled on iPhone and iPad running on iOS 11. But it is straightforward to enable both of these new formats.
Someone at 9to5Mac demonstrated the use of HEIF and HEVC formats on an iOS 11 powered device (see images below). As is clearly evident from the shots shown below that the new format not only helps save storage space by shrinking the size of the photo, it also does so without compromising the image quality.
In testing I went out at night and took a photo and video of the New York City skyline. The outputted JPG image weighed in at 2 MB, while the HEIC image came in at 1.2 MB. Similarly, the h.264 encoded video was 61.2 MB, while the h.265 (HEVC) video was 33 MB.
With the rapid improvement in smartphone and tablet camera technology, anything captured or recorded in 4K or Full HD takes up considerable amount of storage space due to enhance picture and video quality, even on devices with high internal storage. Things are advancing towards 4K technology, and soon 32GB, 64GB and even 128GB storage options on smartphones/tablets won’t be enough for saving all your photos and videos. Thus, having your images and clips saved into a smaller footprint can help save precious space on mobiles.
How to Enable HEVC / HEIF on iOS 11 Devices
In iOS 11, new video format is handled by HEVC, and photo format by HEIC. Both of these new codecs are an absolute must for those who use their iPhone or iPad as primary gadget to capture videos and images on a daily basis, as it will save storage for other stuff.
Before moving ahead, you need to make sure that your iOS or macOS High Sierra device is compatible with the new HEVC / HEIF feature and what are the hardware requirements to extract full use out of it. Here you can find HEIF and HEVC device compatibility requirements on iOS 11, macOS High Sierra.
Now, to enable and disable HEIF and HEVC photo and video encoding, open the Settings app on your iOS 11 device. Then, head over to Camera > Formats. Here you will see a few options: High Efficiency enables the new formats while the Most Compatible option disables them. It totally up to you whether you want to use these two new media formats. Out suggestion is to keep them enabled if saving storage space is your main concern.
Apple’s new iOS 11 is now out and available to install on iPhone and iPad.
