MKV to MOV Conversion FAQ
How do I convert MKV to MOV without re-encoding the video stream?
+
There is no stream-copy switch on this page. A few pairs copy a compatible video stream into the MOV container without re-encoding it, MKV to MP4 among them, which is quick and loses no quality. Most pairs re-encode the video. MKV is codec-agnostic: H.264, HEVC, VP9 and AV1 video sit happily beside AAC, FLAC, Opus, DTS or Dolby audio in the same file. A MOV normally carries H.264 or HEVC for delivery, or ProRes when it is an editing master, alongside AAC or uncompressed PCM audio.
Both MKV and MOV are modern containers — which should I actually keep?
+
Keep whichever matches where the file is going, because neither is better in the abstract. One of these two is built for playback compatibility and the other for holding everything a file might contain, and they trade against each other exactly along that line. The pragmatic answer for most libraries is to archive in the feature-rich container and export to the compatible one on demand. MKV is the archival container of choice because it stores unlimited audio tracks, soft subtitles, chapter markers and cover art in one file. MOV is the QuickTime container, which Final Cut Pro, Premiere and DaVinci Resolve all open natively.
Will multi-track audio survive MKV to MOV conversion?
+
Usually not. Most conversions keep one audio track, the one with the most channels (normally the main mix), re-encoded for the MOV container, so commentary and alternate-language tracks are dropped. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every track, and so does MP4 to MOV. To keep a different track, remux the MKV with that track first (VLC or ffmpeg can do this), then convert it. MOV is Apple’s QuickTime container, shipped in 1991 and still the format an iPhone, iPad or Final Cut Pro timeline writes by default.
Are subtitle tracks preserved when converting MKV to MOV?
+
On some pairs. MP4 to MOV keeps every text subtitle track. AVI, WMV, MPEG, FLV, VOB and M4V to MKV keep every subtitle track: text subtitles are copied or converted to SRT, and picture-based subtitles such as DVD or Blu-ray ones are copied as they are. MP4, MOV and WebM to MKV keep only the first subtitle track (as ASS), and MP4 to WebM keeps the first one as WebVTT. Other pairs, including MKV to MP4 or MOV and WebM to MP4, drop subtitle tracks, and the converter does not burn them into the picture. Subtitles that are already burned in stay, because they are part of the video frames.
What about MKV attachments (fonts, cover art) when going MKV to MOV?
+
MKV is the only mainstream container that stores arbitrary attached files (TTF fonts for ASS subs, JPG cover art, fan-translated PDF inserts). Going from MKV to MOV drops these attachments when MOV is not MKV — the elementary streams convert, but the attached payload stays in the source. Keep MKV as a backup if you depend on attached fonts.
Which codec does the MOV output use by default?
+
It depends on the MOV 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. MOV files are large, and outside the Apple ecosystem playback support is patchier than MP4 — older Android builds and some Smart TVs will refuse them.
How does HDR (HDR10, Dolby Vision) survive MKV to MOV?
+
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 as it is. When the video is re-encoded, the HDR10 mastering metadata is dropped and Dolby Vision or HDR10+ data is not kept, and with a Quality, Resolution or Frame Rate setting some pairs also reduce the video to 8-bit colour, so an HDR MKV can look washed out in the MOV.
Why is my MOV file smaller / larger than the MKV after conversion?
+
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 MKV 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.
Does the MKV to MOV converter handle 4K / 8K / 60fps content?
+
The converter has no resolution cap of its own; the limit is the upload size allowed on your plan, and 4K, 8K and 60 fps files keep their resolution and frame rate unless you change them. MKV to MP4 or MOV with the default settings copies the video stream, which is quick at any resolution. Other pairs re-encode on CPU and the time grows with the pixel count, so a long 4K or 8K file takes much longer than the same length in 1080p.
Is my MKV file private during MOV conversion?
+
Yes. Uploaded MKV files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted MOV are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
