When Should You Use ICNS vs HEIFS?

Use ICNS When...

Reach for ICNS when your priority is macos application icons, retina display icons — its uncompromising quality ensures every detail is preserved.

Use HEIFS When...

Reach for HEIFS when your priority is ios burst photos, live photos, motion photos — its efficient compression makes sharing fast and storage minimal.

ICNS vs HEIFS: Key Differences

•ICNS and HEIFS diverge on compression: lossless compression for the source, lossy compression for the target.
•Converting from ICNS to HEIFS changes compression type: lossy source becomes smaller but with some quality tradeoff.
•Transparency: Not supported in HEIFS — converting from ICNS will merge transparency into a solid background
•Storage footprint: 100KB to 5MB for multi-resolution icons for ICNS vs varies for HEIFS.
•Use case fit: ICNS targets macos application icons, retina display icons and HEIFS targets ios burst photos, live photos, motion photos — your choice depends on which workflow stage you are serving.

Troubleshooting ICNS to HEIFS Conversion

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