What is HEIC?

HEIC, which stands for High-Efficiency Image Container, is a modern image file format designed to store photos and image sequences with greater efficiency than traditional formats like JPEG or PNG. It is the default photo format on Apple devices starting with iOS 11 and macOS High Sierra, and is based on the High Efficiency Image File Format (HEIF) standard developed by the MPEG group.

HEIC file uses HEVC (High Efficiency Video Coding), also known as H.265, to compress images more efficiently while preserving superior visual quality. In simple terms, it allows for smaller file sizes without compromising image resolution, color depth, or clarity.

But HEIC format isn’t just about compression. It also brings modern image features such as:

• Support for transparency (like PNG)
• Ability to store multiple images in one file (ideal for burst shots and live photos)
• Metadata storage, including location and depth information
• Support for animations and image sequences

Here’s how HEIC file stacks up against JPEG:

Feature	HEIC	JPEG
Compression Efficiency	Higher (uses HEVC)	Lower (uses older standard)
Image Quality	Better at same file size	Lower
Transparency Support	Yes	No
Multiple Images/File	Yes	No
Color Depth	10-bit	8-bit

In essence, HEIC is not just a format — it’s a container that holds images and associated data in a highly optimized and flexible way. That makes it ideal for modern use cases like live photos, depth-based photography, and efficient cloud storage.

Who Created HEIC Format and Why?

HEIC is a format developed by the Moving Picture Experts Group (MPEG), the same group that developed popular MP3 and MPEG video file formats. MPEG developed HEIF, finished in 2015, as an improved next-generation image file format that fixes some of the issues in existing older formats, such as JPEG. Apple's entry into this field eventually proved to be the true impetus to support HEIC.

Apple, in 2017, introduced that all photographs taken on devices running iOS 11 or macOS High Sierra would, by default, be kept in the this format. Why? Apple required a sleek, space-efficient solution with minimal loss of picture quality — as iPhones were recording pictures and video of higher resolutions.

Why Apple Used HEIC

• Storage Optimization: Photos are approximately 50% smaller compared to high-quality JPEGs.
• Next-Generation Features: Depth information, animation support, transparency support, and live photos.
• Future-Friendly: 4K photo ready, augmented reality ready, machine learning edit ready. Apple adopted HEIC, but it's an open standard — i.e., not Apple-centric — and can be used on other systems and devices when there is proper codec support.

Essentially, this format was created to future-proof image storage in addition to advancing digital photography, particularly during an era when media is becoming more complex and file storage is precious.

Which Devices and Platforms Use HEIC?

Ever since Apple purchased it in 2017, the HEIC format has slowly gained momentum on mobile and desktop devices — despite support being still uneven on the device, operating system, and software.

Apple Ecosystem (complete support)

• iPhones and iPads running iOS 11 or later save photos automatically in HEIC, as Apple officially adopted this format for better compression and modern imaging.
• Mac computers running macOS High Sierra (10.13) or later natively support HEIC within apps such as Preview, Photos, and Finder.
• Apple's AirDrop and iCloud maintain this format between devices.

Android Devices (Partial Support)

• Most Android phones — especially Samsung, Google Pixel, and OnePlus — natively support HEIF/HEIC starting from Android 9 (Pie) and beyond.
• However, manufacturer and app support can be different.

Windows (Limited Native Support)

• HEIC file is natively supported by Windows 10 and Windows 11 but usually require the installation of HEIF Image Extensions and HEVC Video Extensions from the Microsoft Store.
• These pictures are editable after installation in Photos app, File Explorer, and certain edit software.

Linux and Open Source Platforms

• Supported through image software such as GIMP, ImageMagick, and libheif, but ordinarily requires manual install or the install of additional codecs.
• Web Browsers and Online Services
• Most web browsers such as Chrome, Firefox, and Safari do not support this format natively — they must first be converted.
• Dropbox and Google Photos are capable of storing HEIC file, but will automatically convert them to JPEG when you look at or share them for improved compatibility.

Quick Compatibility Table

Platform	HEIC Support	Notes
iOS	✅ Full	iOS 11+
macOS	✅ Full	High Sierra+
Android	✅ Partial	Android 9+ (device-dependent)
Windows	⚠️ Requires extension	HEIF & HEVC codecs
Linux	⚠️ Partial	Needs libs/codecs
Web Browsers	❌ Not native	Convert before display

HEIC is growing in reach, but its compatibility gaps — especially on older or non-Apple systems — still require users to rely on conversion tools or additional software.

Why Was HEIC Needed?

With advanced mobile cameras and better image quality, older picture formats such as JPEG started aging. JPEG, developed in 1992, was never designed for high-definition sensors, HDR photography, burst mode, and depth information — all of which are commonplace with modern smartphones.

Major Issues with Older Formats:

• Extensive file sizes considering they are compressed.
• Poor color depth (only 8-bit) that impacts high dynamic range (HDR) pictures.
• No support for functionalities such as transparency, animation, or the combination of many images in one file.
• Lossy compression that distorts image quality with time and saving.

All these limitations grew apparent as customers started capturing Live Photos, Portrait Mode, 4K movies, and caching thousands of images in high definition to the cloud.

HEIC Fixes These Issues by Providing:

• Modern compression using HEVC, keeping files up to 50% smaller than JPEG.
• 10-bit color depth support, perfect for HDR photos and contemporary screens.
• Live Photo storage in a single file by capturing several images (and even audio).
• Metadata and depth data preservation for editing and AI-driven photo improvements.
• Animation support, which JPEG does not support at all.

Overall, HEIC was required to keep up with the speed of changing photography technology while allowing users to save space, enhance image quality, and look towards the future of rich multimedia content.
