If you’ve ever stumbled upon a photo file with a weird .heic extension and wondered, What the HEIC is this, you’re not alone. For many, this format seems to have popped up out of nowhere, replacing trusty old JPEGs without so much as a warning, yet numerous HEIC files may be silently residing in your smartphone’s storage at this very moment. Luckily, by the time you finish reading this article, you’ll not only discover the answer to the question “What is HEIC” but also learn why it’s becoming the go-to format for your smartphone photos.

What is HEIC — Learn the Basics

HEIC, despite resembling a regular word, is essentially an acronym. It stands for High-Efficiency Image Container. It’s the default format for photos taken by modern Apple devices, namely iPhones and iPads. It’s based on HEIF (High-Efficiency Image File), which was developed by MPEG, the same folks who brought you MP3 and MP4.

Essentially, the format stores photos more efficiently while maintaining or improving image quality, which is especially evident when comparing it to older formats like JPEG. In a nutshell, HEIC aims to keep your photo’s quality and, at the same time, get rid of the unnecessary clutter, i.e., extra file size.

Why Was HEIC Introduced?

With the rise of smartphones capable of taking stunning, high-resolution photos, storage has become a critical issue. Even with 128 GB or 256 GB of storage on many devices, it’s not uncommon to run out of space faster than you’d like. That’s where HEIC stepped in, and Apple was the first major company to adopt this technology to solve the problem of insufficient storage.

HEIC offers smaller file sizes—typically around half the size of JPEG files—and similar or higher quality. This means you can store twice as many photos on your device or cloud storage without feeling like you’ve sacrificed anything. In an era where every gigabyte counts, this new format is a natural lifesaver.

Key Features of Apple’s Photo Format

Here are some of HEIC’s most prominent features:

Smaller Size, Excellent Quality
The format uses advanced compression algorithms that encode your photo files without sacrificing their quality. Imagine fitting a full pizza into a box half the size—it’s a little magical.
Support for Modern Features
One HEIC file can contain multiple images, which is perfect for things like Live Photos on iPhones. Besides, it offers 16-bit color depth instead of JPEG’s 8-bit, meaning you’re getting more vibrant, richer-looking images.
Built-in Editing Data
Unlike JPEG, HEIC can save edits like cropping or filters directly in the file, so you can undo them later without creating multiple versions of the same image. Besides, it stores metadata like geographical location, time, and date.
Transparency
Just like PNG, HEIC supports transparency, which, combined with the format’s other impressive features, makes it a jack-of-all-trades in the image world.

Comparing to Other Formats

HEIC vs. JPEG
JPEG has been the gold standard for decades, but it’s starting to show its age. While JPEG files are larger and less flexible, they win in compatibility—every device and software supports JPEG. HEIC, on the other hand, is the younger, sleeker sibling that’s more efficient but sometimes harder to work with outside the Apple ecosystem due to compatibility issues that are yet to be resolved.
HEIC vs. PNG
While PNG is great for lossless compression and transparency, its files can get extremely large, requiring dramatic compression and, consequently, significant loss of quality if used for the web. HEIC offers a middle ground with smaller file sizes and transparency support.
HEIC vs. RAW
RAW files are the choice of professional photographers who need every ounce of detail, but they’re massive and require special software to edit. HEIC, while not as detailed, strikes a balance between quality and practicality.

How to Handle HEIC Files

If you’ve ever tried to open a HEIC file on an unsupported device, you know it can feel like trying to unlock a door with the wrong key. Fortunately, there are solutions:

Convert HEIC to other formats
If compatibility is an issue, converting to other formats is an easy fix. iScanner offers multiple online converters to cover that very task. Using a set of free online converters, you can instantly turn HEIC files into JPG, PNG, or even PDF. The iScanner app offers the same functionality built into the context menus for handling files.
Update Your Software
Make sure your operating system and apps are up-to-date. Many newer versions, like Windows 11 with the latest updates installed, now support new file formats.
Change Your Camera Settings
If you’d rather stick with JPEG, your iPhone lets you switch back to this format in the settings. It’s less efficient, but it guarantees compatibility. In fact, the option to save photos as JPEGs is called “Most Compatible,” meaning you’ll face no complications when sharing your images. Just be aware that your photos will take twice as much storage.

The Future of HEIC

The Apple’s photo format is gaining traction, and its widespread adoption is probably inevitable. It has the potential to replace JPEG as the universal image format, but there are hurdles to overcome—namely, compatibility and patent concerns. For now, HEIC is a fantastic option for personal photo storage if you’re part of the Apple ecosystem. As more users and developers switch to using this format, its advantages will likely outweigh its limitations.

So, what the HEIC is HEIC? It’s the future of photo storage—smaller, smarter, and more versatile than what we’ve used before. While it might not be perfect, it’s a step in the right direction for anyone who values efficiency without sacrificing quality. Whether you’re a tech enthusiast or just someone trying to figure out why your computer can’t open that weird file, understanding the basics is worth your time.
