What is AVIFS?

AVIF Sequence, animated AVIF image format for modern web — stored as image/avif-sequence — uses lossy encoding to handle modern web animations, high-efficiency image sequences. Typical file sizes: varies by content.

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.

When Should You Use AVIFS vs HEIF?

Use AVIFS When...

Reach for AVIFS when your priority is modern web animations, high-efficiency image sequences — its efficient compression makes sharing fast and storage minimal.

Use HEIF When...

Reach for HEIF when your priority is modern photography, ios/macos workflows, efficient storage and sharing — its efficient compression makes sharing fast and storage minimal.

AVIFS vs HEIF: Key Differences

•The core technical difference: AVIFS relies on lossy compression whereas HEIF uses lossy compression.
•Since both AVIFS and HEIF use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
•Transparency: Supports alpha channel transparency
•File sizes: AVIFS files typically range N/A and HEIF files 40-50% smaller than equivalent JPEG.
•Use case fit: AVIFS targets modern web animations, high-efficiency image sequences and HEIF targets modern photography, ios/macos workflows, efficient storage and sharing — your choice depends on which workflow stage you are serving.

Best Practices for AVIFS to HEIF Conversion

→When converting AVIFS to HEIF, check whether HEIF supports transparency — if not, your transparent areas will be filled with a solid color
→Use HEIF for maximum quality archival and AVIFS 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 AVIFS to HEIF Conversion

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