Convert MP4 to Mobile Video — Free Online Converter

MP4 to Mobile Video conversion creates a universally mobile-optimized video file that plays smoothly on both Android and iOS devices. Unlike the device-specific presets (iPhone Video, Android Video), the Mobile Video preset targets the intersection of both ecosystems — H.264 Baseline Profile with AAC-LC audio — producing a single file that works reliably on any smartphone or tablet regardless of manufacturer or operating system.

Our converter constrains resolution, bitrate, and profile to levels that every mobile device manufactured since 2012 can hardware-decode without issues. The result is a lean, portable video file optimized for small screens and mobile network delivery.

When you are distributing video to a mixed audience of iPhone, Android, and other mobile devices, you need one file that works everywhere. The Mobile Video preset eliminates the need to create separate encodes for each platform. It is particularly valuable for messaging apps, corporate video distribution, mobile websites, and any scenario where you cannot control or predict the viewer's device.

Video is encoded as H.264 Baseline Profile Level 3.0 with AAC-LC audio at 128 kbps. Resolution is 1280x720 (landscape) or 720x1280 (portrait), maintaining the source aspect ratio. Video bitrate targets 2 Mbps for consistent mobile network streaming. Frame rate is locked to 30 fps. The faststart flag ensures progressive playback. No B-frames are used (Baseline Profile), which maximizes decoder compatibility at a small compression efficiency cost.
