Format Details
HEIF
HEIF (High Efficiency Image Format) is the generic container format developed by MPEG from which HEIC (using HEVC encoding) is derived. It supports image sequences, live photos, multi-frame images, and audio tracks within a single container, with superior compression compared to JPEG. HEIF is used across Apple, Samsung, and other platforms as a modern alternative to older image container formats.
AVIF
AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec developed by the Alliance for Open Media. It delivers superior compression efficiency compared to JPEG and PNG, often reducing file sizes by 50% or more while maintaining excellent visual quality. AVIF supports HDR, wide color gamut, and transparency, making it an ideal choice for the modern web.
