Optimization Tips

iPhone supports a wide range of formats but performs best with H.265 (HEVC) video and HEIC images. These formats offer better quality at smaller file sizes on iOS devices and take advantage of hardware acceleration.

For video, use H.265 (HEVC) with AAC audio for the best balance of quality and file size. MP4 container is most compatible. For photos, HEIC offers 50% smaller files than JPEG with identical quality. Use MOV for editing workflows.

iPhone models with A12+ chips support hardware-accelerated H.265 encoding and decoding. For AirDrop transfers, HEIC and HEVC formats transfer fastest. iCloud Photos works best with HEIC and HEVC (H.265) formats.
