Video Audio Format Supported by iPhone Duo/18/Pro/Max
File format is not accepted by your iPhone: The solution most recommended by us [85%]
With the iPhone 18 Pro lineup and the new iPhone Duo pushing video, camera, and audio capabilities further, file compatibility still matters when you move media onto an iPhone. Not every video or audio file will play natively, especially when it comes from a PC, download, or another device. Here’s a complete list of iPhone-supported video and audio formats, covering the latest iPhone 18 Pro, iPhone Duo, and earlier models. Unsupported files can be converted to an iPhone-friendly format for smooth playback.
List of Video and Audio Formats Supported by iPhone
Video formats supported: iPhone supports video encoded with HEVC (H.265), H.264, and AV1, along with common MPEG-4 and Motion JPEG video. Newer models also support HDR video, including Dolby Vision and HDR10, depending on the content and device. Support can vary with the codec, container, resolution, frame rate, and encoding settings.
Video recording formats: iPhone records video primarily in HEVC and H.264. Pro models also support Apple ProRes and ProRes RAW for higher-quality video workflows. The latest iPhone 18 Pro and iPhone Duo models support advanced video recording features, while available resolutions, frame rates, HDR modes, and ProRes options vary by model.
Audio formats supported: iPhone supports AAC, MP3, Apple Lossless, FLAC, Linear PCM, Dolby Digital (AC-3), Dolby Digital Plus (E-AC-3), Audible formats, and other Apple-supported audio formats. Newer iPhone models also support Dolby Atmos and spatial audio playback with compatible content.
Note: A file's extension alone does not determine whether it will play on an iPhone. The codec, container, encoding profile, resolution, frame rate, and audio codec can all affect compatibility. When an unsupported video or audio file fails to play, converting it to an iPhone-compatible format is usually the simplest solution. See what to do when HEVC won't play on iPhone.
If Your iPhone Doesn't Accept An Audio or Video
