Will I lose quality converting HEIC to AVIF?▼

Both HEIC and AVIF use lossy compression. There may be minimal quality loss during conversion, but at high quality settings (85-95%), the difference is virtually imperceptible to the human eye.

Will my AVIF file have transparency?▼

AVIF supports transparency, but since HEIC does not include alpha channel data, the converted file will not have transparent areas. You would need a HEIC file with transparency data to take advantage of this feature.

What is the HEIC format?▼

HEIC (High Efficiency Image Container) is the default photo format on Apple devices running iOS 11 and later. It uses the HEVC codec to achieve roughly 50% smaller file sizes than JPEG at equivalent quality, but has limited compatibility outside the Apple ecosystem.
