MOV to MP4 Conversion FAQ
How do I re-encode MOV to MP4 without losing video quality?
+
Upload your MOV file and set Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The MP4 output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM. A MOV normally carries H.264 or HEVC for delivery, or ProRes when it is an editing master, alongside AAC or uncompressed PCM audio. Almost every MP4 in the wild is H.264 video with AAC audio; the container also legally holds HEVC, AV1 and VP9.
Can MOV be converted to MP4 without re-encoding the video?
+
No, not on this page. MOV and MP4 share the same underlying structure, but the converter re-encodes the video for this pair rather than copying the stream, so it takes longer than a container change and the picture is compressed again. Choose High Quality under Quality to keep the most detail. MOV is Apple’s QuickTime container, shipped in 1991 and still the format an iPhone, iPad or Final Cut Pro timeline writes by default. MP4 is ISO/IEC 14496-14, standardised in 2001 and derived from the same QuickTime box layout MOV uses.
My MOV has several audio tracks — do they all survive into the MP4?
+
No. The converter keeps one audio track, the one with the most channels (normally the main mix), and drops the rest; there is no setting to pick a different one. To keep another track, remux the MOV with that track first (VLC or ffmpeg can do this), then convert it. MOV is the QuickTime container, which Final Cut Pro, Premiere and DaVinci Resolve all open natively. MP4 only supports one widely-honoured subtitle format (mov_text), and multi-track audio is unreliable outside desktop players.
Will the MP4 play in a browser when the MOV would not?
+
Yes, and that is usually the whole reason for the conversion. An MOV embedded in a web page either shows a broken player or forces a download, because browsers ship no decoder for it. MP4 plays inline through the native HTML5 video element with no plugin and no external application. MP4 is the safest possible delivery target — every phone, browser, console, editor and Smart TV built in the last decade plays it without extra software.
Which video codec does the MP4 output use?
+
It depends on the MP4 container. MP4, MOV and MKV output use H.264, which plays on practically every phone, browser and TV. WebM output uses VP9. AVI, WMV and MPEG output use the older codecs those formats were designed for.
Will my audio track survive MOV to MP4 conversion?
+
Yes, the main audio track comes through, re-encoded to a codec the MP4 container plays, for example AAC in MP4 and MOV or Opus in WebM. Most conversions keep only that one track (the one with the most channels), so alternate languages and commentary are dropped. MP4 to MOV, and AVI, WMV, MPEG, FLV, VOB or M4V to MKV, keep every audio track.
Can I keep the original framerate when converting MOV to MP4?
+
Yes. The frame rate is kept unless you change it: a 24 fps MOV stays 24 fps in the MP4. The Frame Rate setting can also convert to 60, 30 or 24 fps. It changes the rate only; it does not deinterlace the video or remove 3:2 pulldown.
How much will the file size change going from MOV to MP4?
+
It depends on what happens to the video. MKV to MP4 or MOV with the default settings copies the video stream unchanged, so the size stays close to the source. Most other pairs re-encode it: a high-bitrate MOV usually comes out smaller, while an already heavily compressed one can grow. Smaller File under Quality gives the smallest output, and H.265 in the Codec setting (MP4, MOV and MKV) is usually smaller than H.264 at similar quality but plays on fewer devices.
Will the MP4 file play on iPhone, Android, and Smart TVs?
+
MP4 with H.264 plays on practically every phone, browser and TV. MOV with H.264 plays on Apple devices and most TVs but not on every older Android phone. MKV needs an app such as VLC on iOS, and WebM is at home in browsers. There is no device preset on this page, so choose the target format your device supports.
How long does converting a 1-hour MOV video to MP4 take?
+
There is no fixed time: it depends on the length, the resolution and the target format. Conversions run on our servers' CPUs with software encoders; there is no GPU acceleration. MKV to MP4 or MOV with the default settings copies the video stream and is the quickest. A re-encode to H.264 takes longer, and WebM (VP9) is the slowest target, several times slower than H.264 in our tests.
What is the maximum resolution supported for MOV to MP4?
+
The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and the resolution stays as it is unless you choose 1080p, 720p or 480p. There is no HDR processing or tone mapping. When the video stream is copied (MKV to MP4 or MOV with the default settings), HDR10 passes through untouched. A re-encode drops the HDR10 mastering metadata, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR MOV can look washed out.
Is my MOV video private during conversion to MP4?
+
Yes. Uploaded MOV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MP4 are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
