    MOV vs MP4 — what’s the difference?

    Same video insideMOV (Apple QuickTime) and MP4 are both containers. They usually hold the same H.264 video and AAC sound, so converting is just repackaging — no quality lost.
    Why MP4 plays everywhereMP4 with H.264 is supported by every phone, browser, editor and upload form. iPhone MOVs often use HEVC, which many Windows PCs and websites can’t open.

    Frequently asked questions

    How do I convert MOV to MP4 for free?

    Drop your MOV files into the box above and click Convert to MP4. Each video is converted in your browser and gets its own Download button — free, with no sign up, no watermark and no file size limit.

    Is my video uploaded anywhere?

    No. The conversion happens on your own computer or phone, inside the browser. Your video is never sent to a server, which also means there is no upload wait and no size limit.

    Does converting MOV to MP4 lose quality?

    Usually not at all. Most MOV files already hold H.264 video and AAC sound, which MP4 supports, so the tool copies them into an MP4 without re-encoding — the picture and sound are bit-for-bit the same, and it takes seconds. Videos in HEVC (iPhone “High Efficiency”) are re-encoded to H.264 at a high bitrate so they play everywhere.

    How do I convert an iPhone video to MP4?

    AirDrop or copy the video to your computer, or open this page on your iPhone, and drop the MOV here. iPhone videos in HEVC become H.264 MP4s that play on Windows, Android, WhatsApp, Instagram and websites. Portrait videos stay portrait.

    Why won’t my MOV play on Windows or upload to a website?

    MOV is Apple’s QuickTime format, and iPhone MOVs often use HEVC, which many Windows PCs, Android phones and upload forms don’t support. Converting to an H.264 MP4 fixes it — that is the most widely supported video format there is.

    Can I compress the MOV and make the MP4 smaller?

    Yes. Choose 1080p or 720p, and turn on Smaller file. That re-encodes the video at a lower bitrate — good for email, WhatsApp, Telegram or Discord. 4K iPhone videos shrink the most.

    Can I convert several MOV files at once?

    Yes. Drop as many as you like; they convert one after another and each gets its own Download button.

    Can I convert MOV files over 1 GB, 2 GB or 5 GB?

    Yes. There is no file size limit, because nothing is uploaded — the file is read in pieces straight from your disk. Large MOV files of several gigabytes convert fine on a computer; on a phone, keep files under about 1 GB.

    How do I convert MOV to MP4 on a Mac or MacBook?

    Open this page in Safari or Chrome on your Mac, drop the MOV file in and click Convert to MP4. No software to install. (QuickTime Player can only export to MOV with File → Export, so it can’t make an MP4 directly.)

    How do I convert MOV to MP4 on Windows or Android?

    Open this page in Chrome or Edge, drop the MOV file in and click Convert to MP4. It works the same on Windows 10/11, Chromebooks and Android phones — no app or download needed.

    Which browsers work?

    Chrome, Edge and Safari on computers, iPhone and Android. Copying H.264 works in any modern browser; converting HEVC needs Chrome, Edge or Safari (Firefox can’t read HEVC).

    Can I remove the sound?

    Yes — tick Remove sound before converting.
