MOV to MP4 Converter — Free, No Sign-Up | XConvert

Convert MOV to MP4 Online — Free

To convert MOV to MP4, upload your .mov file — an iPhone clip or QuickTime export — to XConvert and click Convert. The file is re-encoded on our servers at a visually-lossless default preset and returns as a universally-playable MP4, with no sign-up or watermark.

Real result: the default "Very High" preset encodes H.264 at CRF 18 — the visually-lossless tier — so the MP4 is indistinguishable from the source in side-by-side viewing, while now playing on Windows, Android, editors, and the web where MOV often won't.

How to Convert MOV to MP4 Online

1. Upload Your MOV File: Drag and drop or click "Add Files" to select MOV recordings from iPhone, QuickTime exports, screen recordings, or camera footage. Batch is supported — drop in an entire folder and each file converts in parallel.
2. Pick Quality Preset or Bitrate Mode: Default is the "Very High (Recommended)" Quality Preset, which targets visually-lossless output. Switch to Specific file size to aim the encode at an exact MB value, Constant Bitrate for predictable streaming sizes, Variable Bitrate for smaller files at the same quality, or Constant Quality to fine-tune with a CRF slider (18 = visually lossless, 23 = default, 28 = noticeably smaller). To force a specific output codec — H.264 for older Windows machines, for example — click Show All Options and pick it under Video Codec.
3. Resize or Trim if Needed (Optional): Under Video resolution, keep original, pick a Preset Resolution (2160p / 1440p / 1080p / 720p / 480p / 360p / 240p), scale by Resolution Percentage, or enter custom Width × Height (aspect ratio is locked unless you choose Width × Height explicitly). Under Trim, pick Time Range and enter start time + duration in seconds or HH:MM:SS.sss format.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared. Download individually or as a ZIP.

Why Convert MOV to MP4?

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:

• iPhone videos for Windows or Android recipients — iPhones record H.264 or HEVC inside a .mov container. Sent over email or messaging, Windows recipients frequently hit "codec not supported." Converted to an MP4 with the H.264 codec, the same footage plays on every platform.
• Social media uploads — YouTube, Instagram Reels, TikTok, X, Facebook, and LinkedIn all process MP4 faster and more reliably than MOV. Several platforms transcode MOV server-side and sometimes drop quality; converting first puts you in control of the encode settings.
• Editing software compatibility — DaVinci Resolve, CapCut, Shotcut, Premiere Rush, and most consumer editors prefer MP4 input. MOV with Apple-specific tracks (ProRes, Animation, alpha) often needs an extra remux pass.
• Smaller file sizes — Re-encoding with H.265 or AV1 typically cuts size 30-50% with no visible quality loss. Useful for messaging caps: Discord free 10 MB / Nitro Basic 50 MB / full Nitro 500 MB, Gmail 25 MB.
• Long-term archive — MP4 has more than two decades as an ISO standard and decades of guaranteed playback ahead. Apple has occasionally adjusted MOV codec defaults (H.264 → HEVC by default in iOS 11); MP4 is more stable for archives.

iPhone HEVC Videos: Get an MP4 That Plays on Windows

Since iOS 11, iPhones record video in HEVC (H.265) by default, and Windows doesn't ship an HEVC decoder — which is why an iPhone clip that looks fine on your phone shows a black frame or "codec not supported" on a PC. One default worth knowing: with no codec selected, this converter keeps the source codec — an HEVC MOV becomes an HEVC MP4, which still won't open on a Windows machine without the codec extension. To guarantee playback everywhere:

1. Upload your .mov file.
2. Click Show All Options and set Video Codec to H.264.
3. Click Convert.

The resulting H.264 MP4 plays on every Windows version since 7, older Android phones, smart TVs, and projectors — no codec packs on the recipient's end. Expect the H.264 file to be moderately larger than the HEVC original; that's the price of universal compatibility. If future videos should skip this step entirely, set your iPhone to Settings → Camera → Formats → Most Compatible, which records H.264 directly.

Frequently Asked Questions

How do I convert MOV to MP4?

Upload the MOV file to XConvert, leave the default "Very High" quality preset, and click Convert. The video is re-encoded into an MP4 container on our servers at a visually-lossless setting, so it looks identical to the source while gaining broad compatibility — it now plays on Windows, Android, video editors, and the web. If the clip came from an iPhone and must play on Windows, also set Video Codec to H.264 under Show All Options.

Can I convert MOV to MP4 without losing quality?

Converting here always re-encodes the video — there is no pass-through stream copy, so the output is a fresh encode rather than a bit-for-bit copy of the original stream. In practice that distinction is invisible: the default "Very High" preset encodes H.264 at CRF 18 (HEVC at CRF 17), the tier video engineers class as visually lossless, and by default the source codec is kept (H.264 in → H.264 out) so there's no cross-codec generation loss. To be explicit about quality, switch to Constant Quality and set CRF 18 or lower. If you need a pixel-identical archival copy, keep the original MOV; for sharing and playback, visually lossless is the practical ceiling.

How do I convert iPhone videos to MP4?

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.

Should I pick H.264 or H.265 when converting?

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.

Can I trim or cut the video while converting?

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.

Can I batch convert multiple MOV files at once?

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 on our servers and downloads individually or as a single ZIP.

What's the file size limit?

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.

Why does my MOV not play on Windows?

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. The fix: upload the MOV here, open Show All Options, set Video Codec to H.264, and convert. The result plays on every Windows version since 7 without installing anything. (Installing Microsoft's HEVC Video Extensions also works, but only fixes your machine — converting fixes the file for every recipient.)

How do I convert MOV to MP4 for email or WhatsApp?

Choose Specific file size under File Compression and aim a little under the cap you're facing — about 20 MB for Gmail's 25 MB attachment limit (MIME encoding inflates attachments in transit), or just under 10 MB for Discord's free tier. The encoder works back from your clip's duration to pick a bitrate that lands near the target. WhatsApp re-compresses any video sent as media regardless of your settings; sending the converted MP4 as a document sidesteps that and preserves your quality. Already have an MP4 that's just too big? Run it through Compress MP4 instead of re-converting.

Can I just rename my .mov to .mp4?

Sometimes. 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, and an HEVC file stays unplayable on Windows no matter what it's called. Converting properly re-encodes every stream into MP4-legal codecs, so the output plays everywhere regardless of what the MOV contained.

Can I convert MP4 back to MOV?

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.
