Since the release of iOS11 and macOS High Sierra in 2017, HEIC files have become the standard image format for Apple users across the globe. Find out how to edit and convert your HEIC images and discover how this image file compares to similar formats.
What is a HEIC file?
When you take a photo on your iPhone or iPad, the image – or images, in the case of dual cameras and live photos – saves as an HEIC file.
HEIC stands for High Efficiency Image Container. The format is an updated variant of the High Efficiency Image Format (HEIF), traditionally used by Apple across its mobile devices.
Apple uses HEIC for HEIF images. HEIF essentially saves images in higher quality than JPEG while also using less space thanks to advanced compressive technology. This space-saving file format uses High Efficiency Video Coding (HEVC) to compress and store images on device drives — taking up half the space of other image file formats, like JPEGs.
Each HEIC file uses the .heic or .heics extension, depending on the number of images inside. The file also contains the relevant metadata describing each image’s size, resolution, location, and more.
History of the HEIC file.
While HEIC has grown in popularity due to being Apple’s standard file format, the Moving Picture Experts Group (MPEG) developed the original HEVC and HEIF technologies.
Apple previously adopted MPEG’s Advanced Audio Coding (AAC) standard for iTunes, and newer iPhones started using the HEVC/H.265 video format in the mid-2010s. So it was the natural next step for Apple operating systems to move to HEIC files in 2017 as part of the iOS11 and macOS High Sierra updates.
In switching from JPEG to HEIC, Apple improved their space-saving capabilities and kept up with the increasing quality of their smartphone cameras. This later led to other manufacturers, such as Microsoft and Canon, embracing the HEIF format.
What are HEIC files used for?
With their high-quality images and space-saving capabilities, HEIC files are a great option for any number of personal and professional purposes.
Whether you’re an online influencer or professional photographer, HEIC files give you the flexibility to store many photos in impressive resolution – all on one device.
Capture the action.
Make the most of your ability to store multiple images in one HEIC file with live photos or the burst mode functionality. With a single click, you can capture multiple high-quality action shots of a moving subject.
Creating an animation.
You can also convert HEIC files into GIFs to make moving animations from your stored sequence of images.
How to open a HEIC file.
HEIC files are the default format for images across your Apple devices, so it should be easy to open them on your Mac. Just right-click on the file and select Open with Preview – the file should then launch in the Preview program. Alternatively, you can import the files to your Photos app or upload them to Dropbox.
To open an HEIC file in Windows, you will need to update to version 18.09 of Windows 10 or later. You can then install the HEIF Image Extensions support tool from the Microsoft Store. To ensure your HEIC files retain their video functionality, you will also need to purchase the HEVC Video Extensions tool. Once these are all installed, you should be able to double-click on an .heic file, and it will open in the default Photos app.
How to create and edit a HEIC file.
