The primary video formats supported by iPhone include MOV, MP4, and M4V encoded with H.264 or MPEG-4 with AAC audio. Since iPhone 8, X and 8 Plus, Apple has added support for the high efficiency video codec (HEVC) to play back 4K videos. But iPhone still does not support MKV, WebM, WMV, MPG, and VOB. Here are iPhone supported video formats in detail:

• Video container formats: MP4, MOV (QuickTime), M4V, AVI
• Video codec formats: MPEG-4, H.264 (AVC), H.265 (HEVC), M-JPEG (for AVI)
• Audio codec formats: AAC-LC stereo, PCM stereo (for AVI)

Note that only the latest iPhone models support all the formats listed above. Older models may not work well with some of the formats such as HEVC. The safest way to play a video on iPhone successfully is to convert the video to MP4 (H264/AAC) format. In the following, you will know the best iPhone video converter to convert video to iPhone format quickly.

If your iPhone cannot play a video, it’s likely because the video uses an unsupported format. Please note that iPhones only support playing MP4, MOV, and M4V files with specific encodings (such as MPEG4 or H.264 video with AAC audio). Newer formats like HEVC and DTS are supported only on more recent iPhone models.

That’s all I wanted to share about the iPhone video formats and the whole process of how to convert video for iPhone. I hope this article is useful. Thank you for reading.

iPhone supports MP4, MOV, and M4V videos encoded with MPEG-4, H.264, H.265 with AAC stereo audio and AVI file encoded with M-JPEG. But models before iPhone 8 do not support H.265 codec and cannot play 4K videos as well.

MOV and MP4 are digital container formats used to contain video, audio and subtitle data. They are basically the same and supported by iPhone natively. Therefore, MOV and MP4 are both good for iPhone.

It may be that your MP4 file is encoded with a format unsupported by your iPhone or the encoding settings are too powerful for your iPhone to handle. iPhone will play MP4 only when the video is encoded with the following specifications:

• Video codec: MPEG-4 (Simple Profile), H.264 (High Profile level 4.2), H.265
• Audio codec: AAC-LC stereo
• Frame rate: max 30 fps
• Resolution: max 4K (H264/HEVC) or max 480P (MPEG4)

You can use the MP4 to iPhone converter in this article to convert the unplayable MP4 to iPhone properly.

Open WonderFox HD Video Converter Factory Pro on your PC and follow the steps below:

• Add your MP4 video to the program.
• Choose an iPhone profile or select H264 as the output format.
• Convert MP4 to iPhone at once.

No, directly open a WMV file on iPhone is impossible. You need to convert WMV to an iPhone-friendly format first.

Usually, no. Most AVI files are DivX or Xvid-encoded, yet iPhone only supports legacy AVI files encoded with M-JPEG video and PCM stereo audio.
