What iPhone needs
iPhone plays MP4 or MOV with H.264 or HEVC video and AAC audio. MKV, AVI, WMV and WEBM files usually will not open in Photos. This converter outputs H.264 High profile, up to 1080p, AAC stereo sound, with the "fast start" flag so it streams straight away.
Good to know
Output is MP4 with H.264 video (yuv420p, the colour format every player supports), AAC stereo at 48 kHz, and the index moved to the start of the file so playback and uploads begin immediately.

Frequently asked questions
Why H.264 and not HEVC?
H.264 plays on every iPhone ever made and on any device you might share it with. HEVC is smaller, but some older devices and Windows PCs cannot play it.
Is the iPhone Video Converter free?
Yes, completely free, with no sign-up and no watermark. Files up to 1 GB each can be converted, and there is no daily limit.
Are my files safe?
Yes. Files are converted locally in your browser and are never uploaded. When you close the page, nothing is left behind.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern mobile browsers. Short files work best on phones; for long or high-resolution videos a computer is faster.
