Supports: MOV
To convert MOV to MP4, upload your .mov file — an iPhone clip or QuickTime export — to XConvert, keep the H.264 video, and click Convert. The file is processed on our servers and returns as a universally-playable MP4 in seconds, with no sign-up or watermark.
Real result: because the H.264 video is usually preserved, the MP4 looks essentially identical to the source and converts fast, while now playing on Windows, Android, editors, and the web where MOV often won't.
MOV is Apple's QuickTime container, published as a proprietary format in 1991 and opened in 2001. MP4 (ISO/IEC 14496-14, standardized in 2003) was derived directly from the QuickTime File Format — the ISO used Apple's spec as the foundation. The two containers can hold the same codecs (H.264, H.265/HEVC, AAC), but MP4 wins on cross-platform support: Windows, Android, smart TVs, Roku, Chromecast, every modern browser. MOV often stalls on Windows Media Player or non-Apple devices without extra codec packs. Common reasons to convert:
-c copy). Most iPhone recordings qualify.| Property | MOV | MP4 |
|---|---|---|
| Standard | Apple QuickTime File Format (public spec 2001) | ISO/IEC 14496-14:2003 (derived from QuickTime) |
| Native playback | macOS, iOS, QuickTime, VLC | Windows, Android, browsers, smart TVs, all modern OSes |
| Typical codecs inside | H.264, HEVC, ProRes, Apple Animation, AAC | H.264, H.265, AV1, VP9, AAC, MP3 |
| File size | Larger by default (less codec flexibility in Apple workflows) | Smaller (better codec/bitrate options) |
| Pro features | ProRes, Animation, alpha channel, multi-track edit metadata | Generic — limited to standard codec set |
| Best for | Editing on Mac, ProRes intermediates, Final Cut Pro | Sharing, streaming, archiving, social uploads |
| Mode | What it does | Pick when |
|---|---|---|
| Quality Preset | One-click Highest → Lowest preset (default "Very High") | You want a sensible default with no tweaking |
| Specific file size | Auto-tunes bitrate to hit an exact MB target | You're hitting an attachment or upload cap |
| Constant Bitrate (CBR) | Fixed bits per second across the entire video | Live streaming, predictable sizing, broadcast |
| Variable Bitrate (VBR) | Spends more bits on complex scenes, fewer on simple | Best quality-per-MB; default for most uploads |
| Constant Quality (CRF) | CRF 0-51 — 18 = visually lossless, 23 = default, 28 = small | You want consistent perceived quality across clips |
| Constraint Quality (capped VBR) | VBR with a ceiling bitrate | Streaming where bandwidth has a hard ceiling |
| Codec | File size (relative) | Compatibility | Best for |
|---|---|---|---|
| H.264 | 100% (baseline) | Every device made since 2010 | Default — universal compatibility |
| H.265 / HEVC | ~60% | Safari 11+ (iOS) / 13+ (macOS), Chrome 107+ (Oct 2022, partial), Edge, hardware decode on most 2017+ devices | Smaller files, 4K, iOS sharing |
| VP9 | ~70% | All major browsers, YouTube, Android | Web embedding, royalty-free |
| AV1 | ~50% | Chrome 70+, Firefox 67+, Safari 17+, modern smart TVs | Streaming, smallest files at high quality |
If you also need to shrink the result further, follow up with Compress MP4 to reduce video file size after converting. Going the other direction for Final Cut Pro? See MP4 to MOV.
Upload the MOV file to XConvert, keep H.264 to preserve quality, and click Convert. The video stream is re-wrapped into the MP4 container on our servers, so quality stays essentially identical to the source while the file gains broad compatibility — it now plays on Windows, Android, video editors, and the web.
If your MOV already contains H.264 or H.265 video and AAC audio (true for almost all iPhone recordings), the conversion is a container remux — the audio and video streams move into the MP4 container with no re-encoding and zero quality loss. This is the same -c copy operation ffmpeg performs. If you change codecs (e.g., H.264 → AV1) or compress, set CRF to 18-20 to stay visually lossless. The default "Very High" preset produces output indistinguishable from the source in side-by-side viewing.
Upload the.mov directly. AirDrop to a Mac and drop in, or share to a cloud (iCloud Link, Dropbox, Drive) and download to the device running XConvert. The tool handles iPhone HEVC and H.264 recordings, including 4K @ 60fps, Cinematic mode, slow-motion clips, and ProRes (iPhone Pro models). Pick H.264 output for the broadest compatibility, or keep HEVC if your recipient is on iOS/macOS and you want the smallest file.
H.264 if you need maximum compatibility — work laptops, older Windows builds, smart TVs from before 2018, web embeds for unknown audiences. H.265 if you want roughly 40% smaller files at the same quality and your audience is on modern hardware (Apple devices since iPhone 6, Android 9+, Chrome 107+, Edge, hardware-accelerated playback on most 2017+ devices). H.265 takes longer to encode and decode but is now broadly playable.
Yes. Under Trim, select Time Range and enter a start time and duration. Both accept seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Trimming first skips unwanted footage and shrinks the output before any encoding work, which speeds up the convert step substantially on long source clips. For more advanced editing see Video Cutter.
Yes. Upload as many MOV files as you want — there's no quantity limit. Apply the same settings to all of them or set per-file options. Each file converts in parallel withon our servers and downloads individually or as a single ZIP.
XConvert handles large MOV files including multi-GB 4K and 8K recordings from cameras and iPhones. Conversion runs on our servers, so the practical limit is upload size and connection speed and the patience for the upload. There's no fixed per-file cap and no quantity limit on batch jobs.
Older Windows builds and many non-Chromium browsers don't ship with the codec needed to decode HEVC (H.265), which iPhones use by default for video since iOS 11. The MOV file itself is fine — the system just can't open it without an extra codec pack. Converting to MP4 with H.264 codec resolves this in one step and produces a file that plays on every Windows version since 7.
Sometimes. Apple's own support docs note that for H.264 MOV files, renaming the extension to.mp4 often works because the container structures are nearly identical. But it fails silently if the MOV uses ProRes, Animation, PCM audio, or other codecs not allowed in MP4 — the file appears renamed but won't play in most MP4 players. XConvert checks codec compatibility and remuxes losslessly when possible, or re-encodes the offending stream to a valid MP4 codec automatically.
Yes — see MP4 to MOV for the reverse direction (useful for Final Cut Pro, older QuickTime workflows, and ProRes intermediates). If you only want to shrink your existing MOV without changing format, use Compress MOV.
