What is HEIF?

HEIF (High Efficiency Image File Format) is a modern container format that stores images encoded with the HEVC (H.265) codec. It delivers significantly smaller file sizes than JPEG while maintaining superior image quality.

What is AVIF?

AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.

When Should You Use HEIF vs AVIF?

HEIF vs AVIF: Key Differences

• •HEIF uses lossy compression while AVIF uses lossy compression — both take the same approach to file size management.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •Transparency: Supports full alpha channel transparency
• •Storage footprint: 40-50% smaller than equivalent JPEG for HEIF vs 40-50% smaller than JPEG/PNG for AVIF.
• •HEIF is optimized for modern photography, ios/macos workflows, efficient storage and sharing while AVIF is designed for modern web, next-generation web applications — choose based on your specific workflow needs

Advantages of HEIF

• ✓The lossy nature of HEIF means file sizes stay reasonable while handling Modern photography, iOS/macOS workflows, efficient storage and sharing efficiently.
• ✓From mobile devices to enterprise servers, HEIF is recognized and supported everywhere.
• ✓Storage and bandwidth costs drop significantly when using HEIF thanks to its efficient compression.
• ✓HEIF is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Industry Applications

Best Practices for HEIF to AVIF Conversion

• →When converting HEIF to AVIF, check whether AVIF supports transparency — if not, your transparent areas will be filled with a solid color
• →Use AVIF for maximum quality archival and HEIF for smaller file sizes when quality is less critical
• →Optimize images for web to reduce page load times — tools like our converter let you adjust quality settings before conversion
• →Maintain original aspect ratio to avoid distortion during conversion
• →Always keep a backup of your original files before converting
• →Choose the appropriate quality settings for your specific use case

Troubleshooting HEIF to AVIF Conversion

• !Converting HEIF to AVIF gives blurry output → increase the quality setting before conversion
• !Colors look different in AVIF than HEIF → check color profile mismatch (sRGB vs Adobe RGB)
• !File size changed more than expected → AVIF uses different compression, file size differences of 2-5x are normal
• !Transparent areas in HEIF turned white in AVIF → AVIF may not support transparency
