About HEIC Image
HEIC (High Efficiency Image Container) is a modern image format based on the HEVC video codec, used by default on Apple devices since iOS 11. HEIC files are roughly half the size of JPEG at the same visual quality, while supporting depth maps, live photos, and image sequences.
Strengths
- ✓ 50% smaller than JPEG at equivalent quality
- ✓ Supports depth maps and live photos
- ✓ Stores image bursts and sequences
- ✓ 10-bit color depth for HDR
Limitations
- • Limited Windows and Android support
- • Not widely supported on the web
- • Patent licensing concerns (HEVC)
- • Many apps require conversion to view
Developed by MPEG (ISO/IEC) (2015)
About JPEG XL Image
JPEG XL is a next-generation image format designed as the ultimate successor to JPEG. It supports both lossy and lossless compression with industry-leading efficiency, progressive decoding, and can losslessly recompress existing JPEG files to 20% smaller without any quality loss.
Strengths
- ✓ Superior compression to JPEG, WebP, and AVIF
- ✓ Lossless JPEG recompression (20% savings)
- ✓ Progressive decoding for fast previews
- ✓ HDR and wide gamut support
Limitations
- • Very limited browser support currently
- • New format still gaining adoption
- • Encoding can be slow
- • Editor support still emerging
