HEIC vs AVIF: What's the Difference & Which Should You Use? (2024 Guide)
HEIC vs AVIF at a Glance
The Battle of Next-Generation Image Formats
The world of digital images is evolving rapidly. While JPG and PNG have dominated for decades, two modern formats are challenging their supremacy: HEIC (High Efficiency Image Container) and AVIF (AV1 Image File Format). Both promise dramatically smaller file sizes with equal or better quality, but they serve different purposes and audiences.
If you're wondering which format to choose for your photos, website, or workflow, this comprehensive comparison will help you make the right decision. We'll examine real-world performance, compatibility, use cases, and provide practical recommendations for different scenarios.
Quick Decision Guide
- Choose HEIC if: You're primarily in the Apple ecosystem (iPhone, Mac, iPad)
- Choose AVIF if: You're optimizing for web performance and cross-platform compatibility
- Convert to JPG if: You need universal compatibility across all devices and platforms
Understanding Each Format
HEIC (High Efficiency Image Container)
- Developer: Apple (based on HEIF standard)
- Released: 2017 with iOS 11
- Compression: H.265/HEVC codec

Frequently Asked Questions
Is AVIF better than HEIC?
AVIF offers better compression than HEIC (20-30% smaller files) and has broader platform support. However, HEIC has better current browser support and is the established standard on Apple devices. The best choice depends on your specific use case and target audience.
Which browsers support AVIF vs HEIC?
AVIF is supported by Chrome, Firefox, and Opera (about 75% browser support). HEIC has limited browser support, mainly Safari and some newer versions of Edge. For web use, AVIF currently has better compatibility across different browsers.
Should I use HEIC or AVIF for photography?
For photography, HEIC is better if you're primarily working within the Apple ecosystem (iPhone/Mac workflow). AVIF is better for web publishing and cross-platform sharing. Both offer excellent quality at smaller file sizes than traditional JPG format.
Can I convert between HEIC and AVIF directly?
While direct conversion is technically possible, it's not recommended as both are lossy formats. Converting HEIC→AVIF or AVIF→HEIC can result in quality degradation. It's better to convert from the original source or convert both to a universal format like JPG when needed.
Which format is better for website performance?
AVIF is generally better for website performance due to superior compression and broader browser support. However, implementing a progressive enhancement strategy with AVIF as primary and JPG as fallback provides the best balance of performance and compatibility.
Will HEIC or AVIF eventually replace JPG?
Both formats are gradually gaining adoption, but complete JPG replacement will take years. HEIC is becoming standard in mobile photography, while AVIF is growing in web applications. JPG remains important for universal compatibility and will likely coexist with newer formats for the foreseeable future.
Making the Right Choice
The choice between HEIC and AVIF isn't about finding a universal winner—it's about matching the format to your specific needs and audience. Both represent significant improvements over traditional image formats, offering superior compression and quality.
Your Decision Framework
- Apple Ecosystem Users: HEIC for storage and workflow efficiency
- Web Developers: AVIF for performance with JPG fallbacks
- Cross-Platform Sharing: Convert to JPG for maximum compatibility
- Future-Proofing: Monitor both formats as adoption grows
Remember that the best format strategy often involves using multiple formats strategically. iPhone users might capture in HEIC for efficiency, convert to JPG for sharing, and use AVIF for web publishing—each format serving its optimal purpose.
