Convert M4V to MP4 Offline — iTunes Videos Without Apple

Step 1: Select Your M4V File

Open your DRM-free M4V file from your device. The file is loaded locally in your browser — no upload to any server occurs.

Step 2: Set Quality

DRM-free M4V files often contain high-quality H.264 video. Choose High to do a lossless container remux, or Medium/Low to reduce file size.

Step 3: Convert in Your Browser

FFmpeg.wasm remuxes the M4V container to MP4 — for DRM-free files this is a fast container swap that preserves all video and audio streams without re-encoding.

Step 4: Download the MP4

Save the converted MP4 to your device. It now plays on Android, Windows, smart TVs, and any platform without requiring iTunes.

M4V Container

M4V is Apple's branded version of the MP4/MPEG-4 container. It adds the .m4v extension and optional FairPlay DRM for iTunes Store purchases. The video inside is usually H.264.

MP4 Compatibility

MP4 is the universal standard. Renaming .m4v to .mp4 sometimes works, but a proper container conversion via FFmpeg ensures maximum compatibility across all platforms.

iTunes Dependency

M4V files from older iTunes libraries require iTunes to be installed for playback on Windows. Converting to MP4 removes this dependency entirely.

Cross-Platform Use

MP4 is natively supported by every modern operating system, smart TV, games console, and video platform — no special software or codec packs needed.

Your video never leaves your device. No upload, no server, no data collection at any stage.

FFmpeg.wasm runs on your own CPU — no waiting for uploads or server queues.

Once the page loads, conversion works without any internet connection.
