Convert MP4 to iPhone Video — Free Online Converter

MP4 to iPhone Video conversion tailors your MPEG-4 file to the hardware decoder and display characteristics of Apple's iPhone lineup. Every iPhone since the 3GS has included a dedicated H.264 hardware decoder, and optimizing your video for this decoder ensures smooth playback, minimal battery consumption, and compatibility from the oldest supported iPhone to the latest iPhone 16 Pro Max.

Our converter produces H.264 Main or High Profile with AAC-LC audio, resolution-matched to common iPhone display sizes. The output file plays natively in the Photos app, Safari, and all third-party video players on iOS.

iPhones handle MP4 natively, but not all MP4 encodes are equal on iPhone hardware. A 4K120 ProRes file from a RED camera will overheat an iPhone SE. A VP9 WebM will not play at all. AV1-encoded MP4 only works on iPhone 15 and later. The iPhone Video preset restricts encoding parameters to the universally supported subset, ensuring your video works on every iPhone model you might need to target — from enterprise MDM deployments to personal sharing.
