Will converting MKV to MOV change the video or audio quality?

No, as long as the codecs are QuickTime-compatible. The conversion is a stream copy — FFmpeg moves the existing compressed video and audio data into the MOV container without decoding or re-encoding it, so quality, resolution, and bitrate are unchanged.

My MKV uses HEVC — will the MOV play in QuickTime?

Usually yes on a reasonably recent Mac, since QuickTime added HEVC support some years ago. On older macOS versions without HEVC hardware or software decoding, the MOV may open but play back poorly or not at all — this is a limitation of QuickTime's codec support, not the container conversion itself.

What happens if my MKV uses VP9, AV1, or Opus?

The conversion will typically fail rather than produce a broken file. QuickTime has no native decoder for these codecs, so there is no safe way to repackage them into a MOV container that would actually play.

Do multiple audio tracks or subtitles transfer to the MOV?

No. Only the default video and audio track are carried over. MKV's support for multiple audio languages and embedded subtitle tracks has no direct equivalent in this MOV remux workflow, so extra tracks are dropped.

Can I import the converted MOV straight into Final Cut Pro?

Yes, provided the underlying codec is H.264, HEVC, or ProRes. Final Cut reads the MOV container natively, so as long as the video codec inside it is one Final Cut supports, import should work without additional conversion.

Is MOV basically the same as MP4?

They share the same underlying ISO base media file structure, and MOV actually predates and influenced MP4. In practice, MOV is treated as Apple's native flavor that QuickTime-based tools default to, while MP4 is the more universally standardized format used everywhere else.

Why does the conversion fail with a codec error?

This almost always means the MKV's video or audio codec is not one MOV/QuickTime can represent, most commonly VP9, AV1 video, or Opus, DTS, or Vorbis audio. A full re-encode to an Apple-compatible codec would be needed first, which is a different, lossy operation from this remux tool.

Will the converted MOV play on an iPhone or iPad?

Yes, as long as the video is H.264 or HEVC and the audio is AAC, which is what iOS decodes natively. The MOV container itself is fully supported by the Photos and Files apps on iOS.

How large an MKV file can I convert?

Guest users can convert files up to 40 MB. A free account raises that to 80 MB, and Pro accounts can process files up to 250 MB, all handled locally in your browser.

Why not just rename the .mkv file to .mov instead of converting it?

Renaming the file extension does not change the underlying container structure — QuickTime and other MOV-aware software look at the actual byte layout of the file, not just the extension, so a renamed MKV will still fail to open correctly. An actual remux is required.

Is my video uploaded to a server during conversion?

No. FFmpeg runs as WebAssembly inside your browser tab, so the entire remux happens on your own device and your MKV file never leaves your computer.

What is MKV to MOV?

MKV is the format of choice for movie rips, anime releases, and archival encodes precisely because it can hold almost anything — HEVC or AV1 video, several audio languages, several subtitle tracks, chapters, attached fonts. Apple's ecosystem was never built around it. QuickTime Player, iMovie, and Final Cut Pro are built on the QuickTime File Format (.mov), and macOS and iOS have no built-in Matroska demuxer at all, so an MKV file dropped onto a Mac frequently just refuses to open, or opens in a third-party player that is not part of the native editing chain.

This tool converts MKV to MOV using a stream copy rather than a re-encode: FFmpeg reads the video and audio streams already inside your MKV file and repackages them into a QuickTime-compatible MOV container, provided the codecs involved are ones QuickTime understands — H.264 or HEVC video with AAC or PCM audio being the most reliable combination. Because no decoding or re-encoding happens, the visual and audio quality are identical to the source, and conversion finishes in seconds rather than the minutes a full transcode would take. If your MKV carries a codec QuickTime does not support, such as VP9 or AV1 video or Opus audio, the remux will fail rather than produce a broken file, since there is no safe way to relabel a codec QuickTime cannot decode.

How It Works

FFmpeg inspects your MKV's stream headers to identify the default video and audio codec, then performs a stream copy (-c copy) that lifts the existing compressed data out of the Matroska container and writes it into a QuickTime atom-based MOV structure. This works cleanly when the codecs are ones MOV natively supports — H.264 or HEVC video, AAC or PCM audio — and finishes almost instantly since no frame is ever decoded. Extra audio tracks, subtitle streams, and chapter data present in the MKV are not carried over, as MOV has no equivalent structure for them in this workflow.

How to Use

1
Upload your MKV file
Drag your .mkv file onto the upload zone or click to browse. Nothing uploads to a server.
2
Confirm your MKV's codec if unsure
H.264 or HEVC video with AAC audio converts most reliably; VP9, AV1, or Opus will typically fail since QuickTime cannot decode them.
3
Let FFmpeg load
The first time you convert on this site, the ~30 MB FFmpeg WebAssembly engine downloads once and is cached afterward.
4
Click Convert to MOV
FFmpeg copies the default video and audio streams directly into a QuickTime-compatible MOV container.
5
Wait for the remux to finish
Since no re-encoding happens for compatible codecs, most files finish in a few seconds regardless of length.
6
Download the MOV file
Save the finished .mov file to your device. The original MKV remains untouched.
7
Open it in Apple software
Import into QuickTime Player, iMovie, or Final Cut Pro, or share via AirDrop between Apple devices.
