AVIF vs HEIC 2026：哪个格式更好？ [完整对比]

Format Overview

AVIF and HEIC represent two modern approaches to image compression, each with distinct origins and strengths.

HEIC (High Efficiency Image Container) was developed by the Moving Picture Experts Group (MPEG) and uses HEVC (H.265) codec for compression. It became widely known through Apple's adoption in iOS 11 as the default photo format.

AVIF emerged from the Alliance for Open Media, using the royalty-free AV1 codec. It was designed specifically to be a web-first, open-standard alternative to proprietary formats like HEIC.
