About iTunes Video
M4V is Apple's video file format, used primarily by iTunes and the Apple TV app. Technically, M4V is identical to MP4 — it uses the same MPEG-4 Part 14 container structure. The .m4v extension signals that the file may contain Apple's FairPlay DRM. Unprotected M4V files can be played as MP4 simply by renaming the extension.

Why privacy matters for file conversion
Most online converters upload your files to remote servers where they may be scanned, stored, or shared. This tool is different — the conversion runs in your browser via WebAssembly or the WebCodecs API. Your files stay on your device. Always.

Frequently asked questions
If the M4V file is not DRM-protected, you can simply rename it from .m4v to .mp4. For DRM-protected iTunes purchases, you'll need to use Apple's own tools to re-download in a compatible format.
Yes, completely free with no file limits. The conversion engine runs directly in your browser — we have zero server costs for processing, so we can offer it at no charge.
Your file never leaves your device. The conversion engine runs 100% in your browser using WebAssembly or the WebCodecs API. We have no access to your files — no uploads, no logs, no data collection whatsoever.
On desktop browsers (Chrome, Firefox, Edge) files up to 500 MB convert reliably. On Safari (macOS) the practical limit is around 200 MB. On iPhone and iPad, keep files under 50 MB — iOS enforces tight memory limits for browser-based processing.
On your first visit, the browser downloads the conversion engine (24–50 MB depending on which backend is used). This is cached locally, so subsequent conversions load much faster.
Chrome, Edge, and Brave use hardware-accelerated WebCodecs when the format is supported — this is 5–10× faster than software encoding. For unsupported formats the tool falls back to ffmpeg.wasm, where Firefox typically performs best.
