HEIC vs JPG: What Is HEIC and How to Convert It

April 6, 2026 · 4 min read

If you have ever tried to open an iPhone photo on a Windows computer and got an error, you have encountered the HEIC format. Here is everything you need to know about HEIC, how it compares to JPG, and how to convert between them.

What Is HEIC?

HEIC stands for High Efficiency Image Container. It is a modern image format that Apple adopted as the default for iPhones and iPads starting with iOS 11 in 2017. HEIC is based on the HEVC (H.265) video codec and produces significantly smaller files than JPG while maintaining the same visual quality.

HEIC vs JPG: Key Differences

File size: HEIC files are roughly 50 percent smaller than equivalent JPG files at the same quality
Quality: HEIC preserves more detail and color information than JPG
Compatibility: JPG works everywhere. HEIC is mainly supported on Apple devices and newer Windows 10/11 systems
Transparency: HEIC supports transparency, JPG does not
Editing: HEIC supports non-destructive editing and can store multiple images in one file

Why Does My iPhone Use HEIC?

Apple chose HEIC because it saves significant storage space. A typical iPhone photo in HEIC format is about 2MB, while the same photo in JPG would be 4MB or more. When you take thousands of photos, this adds up to gigabytes of saved storage.

You can change your iPhone to save as JPG instead: go to Settings, then Camera, then Formats, and select Most Compatible. However, you will use more storage space.

When to Convert HEIC to JPG

You need to convert HEIC to JPG when:

Sharing photos with someone on Windows or Android who cannot open HEIC files
Uploading to a website or platform that only accepts JPG
Editing in software that does not support HEIC
Sending photos via email to recipients with older devices
