Open a compatible file
Choose one Apple-readable video or audio file from Photos or Files. Compatible AAC and MP3 files can be used as audio sources; MP3 remains input-only.
Media Format Conversion · On device · iPhone + iPad
Change the format. Keep the workflow local.
Open a video or audio file that Apple’s media frameworks can read, choose a compatible destination, and create a new file without uploading the source. Video can stay video or, when it contains sound, become an audio-only result.
One source, supported destinations
How to convert a media format on iPhone.
ClipFlow shows only the output types that fit the source media. Actual readability still depends on the container, codec, device, and operating system.
Choose the destination
Keep video as MP4, MOV, or M4V. For audio—or a video that has an audio track—choose AAC, M4A, WAV, AIFF, or CAF.
Create a new result
Convert on the device, preview the result, then save, share, or continue with a compatible next tool.
Video and audio output formats
A compatible video source can produce MP4, MOV, or M4V video. When that video contains an audio track, it can also produce an audio-only AAC, M4A, WAV, AIFF, or CAF file.
A compatible audio source can be converted among AAC, M4A, WAV, AIFF, and CAF. Audio-only input does not generate a video file.
Apple-native compatibility boundaries
ClipFlow relies on the media containers and codecs that Apple’s frameworks can read on the current device. AAC and MP3 can both be imported as compatible sources. AAC can also be exported, while MP3 remains input-only. Sources the current Apple runtime cannot decode—including unsupported MKV combinations—are not offered.
A familiar file extension does not guarantee that every codec inside it can be decoded or exported. If Apple’s runtime cannot read a source or create a requested pairing, ClipFlow does not offer that conversion.
Local, non-destructive conversion
Media Format Conversion runs entirely on your device with Apple-native media frameworks. ClipFlow does not upload the source, and the original file remains unchanged.
Changing a container or audio format may still require encoding a new media file; it is not a promise of lossless stream copying. Review the new result before deleting or moving the source.
