Why convert MOV to MP4?

MOV is the QuickTime container Apple uses for recordings from iPhones, iPads and Macs. It works beautifully inside the Apple ecosystem, but Windows, Android phones, smart TVs and countless web apps either refuse to open it or need extra plugins. MP4 is the most widely supported video container in the world, so converting removes those headaches in one step.

You run into this constantly: a MOV that plays perfectly on your iPhone will not upload to some websites, will not drop cleanly into a Windows video editor, and may show up as a black rectangle in a PowerPoint slide or a Google Slides deck. Emailing one to an Android user often ends with them unable to open it at all. Saving the same footage as MP4 sidesteps every one of those problems because H.264-in-MP4 is the format practically all software expects.

Most MOV files already contain H.264 or HEVC video, so VidShift simply repackages the existing streams into an MP4 container without touching the pixels. That means the conversion is lossless and takes seconds, not minutes, no matter how large the clip is. When the video is already H.264, the result is bit-for-bit identical to the source.

Newer iPhones record in HEVC (H.265) to save space, and while HEVC can live inside an MP4 for a lossless result, older devices and browsers do not always decode it. In those cases converting to H.264 gives you the widest possible compatibility at the cost of a re-encode. Either way, everything happens locally in your browser, your video is never uploaded, and there is no size cap beyond your device's memory, no account, and no watermark.

Frequently Asked Questions

Does converting MOV to MP4 lose quality?

No, when the video is repackaged without re-encoding the quality is bit-for-bit identical. Most MOV files already contain H.264 or HEVC video, so VidShift moves the existing streams into an MP4 container untouched.

Why won't my iPhone video play on Windows?

Newer iPhones record in HEVC (H.265) inside a MOV container, which older Windows apps do not support. Converting to MP4 - and if needed re-encoding to H.264 for maximum compatibility - makes the file play on virtually any device or player.

Are my files uploaded to a server?

No. Your files never leave your device. All conversion runs locally in your browser using WebAssembly, so the process is completely private and even works offline after your first visit.

Is there a file size limit?

There is no hard limit. Because nothing is uploaded, the only practical ceiling is your device's available memory. Most computers handle multi-gigabyte files without issue.
