Upload a file to optimize for iPhone
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.
MP4 with H.265 (HEVC) codec offers the best quality-to-size ratio. H.264 is more universally compatible but produces larger files.
Not natively. Third-party apps like VLC or Infuse are required for MKV playback on iPhone.
HEIC is Apple's efficient image format using HEVC compression. It offers 50% smaller file sizes than JPEG with equivalent quality. Supported on iOS 11+ and macOS High Sierra+.
No, iPhone does not have hardware AV1 decoding. Software decoding is possible but drains battery. Stick with H.264 or H.265 for iPhone playback.
iPhone supports up to 4K at 60fps on newer models (iPhone 8+). iPhone 13 Pro and later support ProRes recording at up to 4K 30fps.
No, iPhone does not natively support FLAC. Convert to ALAC (Apple Lossless) or AAC for iPhone playback. Third-party apps like VLC can play FLAC.
