HEIC and JPEG are two of the most common image formats you will encounter, but they serve different purposes. Understanding their differences helps you choose the right format for each situation.
File Size Comparison
The most significant difference between HEIC and JPEG is file size. HEIC uses modern HEVC compression to create files that are 40-50% smaller than JPEG files of equivalent quality. This means a 5MB JPEG photo might be just 2.5MB as HEIC. For device storage, this difference is substantial. However, for sharing and compatibility, the smaller file size of HEIC does not help if the recipient cannot open it.
Image Quality
At the same file size, HEIC delivers noticeably better quality than JPEG. The HEVC codec is more efficient at preserving image detail while discarding less noticeable information. At high quality settings (90% and above), both formats look excellent, but HEIC maintains its advantage at lower bitrates.
Compatibility
JPEG wins decisively in compatibility. Every browser, device, operating system, and software application created in the last 25 years supports JPEG. HEIC, by contrast, is natively supported only on Apple devices (iOS, macOS) and newer versions of Android and Windows (with codec packs). Many web platforms still do not accept HEIC uploads.
Feature Comparison
HEIC supports advanced features that JPEG does not: image sequences, burst photos, depth maps, and Live Photos. HEIC also supports transparency (alpha channel), which JPEG does not. However, these advanced features are only useful within the Apple ecosystem.
When to Use HEIC
- Storing photos on Apple devices to save space
- When you stay within the Apple ecosystem
- When you need advanced features like Live Photos
When to Use JPEG
- Sharing photos with others
- Uploading to websites and social media
- Archiving photos for long-term access
- Printing photos
- When universal compatibility is required
Bottom Line
Use HEIC for storage on Apple devices and convert to JPEG when you need to share or upload photos. HEIC2 makes this conversion quick, free, and private.
