MKV to MOV Converter

How to Convert MKV to MOV Online

1. Upload Your MKV Files: Drag and drop, or click "+ Add Files" to select MKV files from your computer. Batch upload is supported — queue multiple files and convert them in one session.
2. Pick a Quality Preset or Bitrate Target: Default is "Very High (Recommended)" which keeps near-source quality. Drop to High or Medium for smaller files, or switch to Constant Bitrate / Variable Bitrate / Constant Quality (CRF) / Constraint Quality / Specific file size if you need a precise target. The default video codec is H.264 (broad Apple compatibility); change to H.265/HEVC for ~50% smaller files at the same visual quality, or to a copy/passthrough if your MKV already holds an H.264 or HEVC stream and you only want a container rewrap.
3. Resize, Trim, or Adjust Audio (Optional): Use Preset Resolutions (2160p, 1440p, 1080p, 720p, 480p), Resolution Percentage, Width × Height, or "Keep original." Use the Time Range trim to clip start/end. Pick an Audio Codec — AAC is the safest MOV default; PCM works for lossless masters; AC3/EAC3 preserves surround tracks from disc rips.
4. Convert and Download: Click "Convert" and download your MOV. Everything happens on our servers — no sign-up, no watermark, no email required.

Why Convert MKV to MOV?

MKV (Matroska) is a flexible open container designed to hold an arbitrary mix of video, audio, and subtitle tracks, which is why it dominates ripped Blu-rays, anime fansubs, and PC media libraries. MOV is Apple's container, derived from the QuickTime File Format that ISO later used as the basis for the MP4 / ISO Base Media File Format spec. Converting MKV to MOV is almost always about getting an Apple-shaped wrapper around the same video so Apple tools will actually open it.

• Final Cut Pro and iMovie ingest — Final Cut Pro's official supported containers are 3GP, AVI, MOV, MP4, MTS/M2TS, and MXF. MKV is not on that list. The cleanest path to FCP or iMovie is MOV with H.264 or HEVC inside, or ProRes if you have it.
• QuickTime Player native playback — macOS ships without an MKV decoder. Out of the box, double-clicking an MKV opens nothing useful; users install VLC, IINA, or Elmedia. MOV opens with a double-click on every Mac going back two decades.
• AirPlay to Apple TV — AirPlay mirrors what the source app can play. Photos, QuickTime, and most Apple apps refuse MKV, so AirPlay never sees the stream. MOV streams directly to Apple TV and HomePod-attached displays.
• iPhone and iPad Photos library — Files.app will store an MKV but Photos won't index it, and iCloud Photos won't sync it. MOV is the format the iPhone camera itself writes, so it round-trips cleanly.
• Keynote, Pages, and DaVinci Resolve on Mac — Apple's iWork apps and most Mac-native editors expect MOV, MP4, or M4V. Even Resolve, which supports MKV on Windows and Linux, drops MKV support on macOS unless you transcode.
• Client deliverables on macOS shops — Sending a colorist or editor an MKV virtually guarantees a "can you re-export?" reply. MOV with H.264 or ProRes is the lingua franca.

Frequently Asked Questions

Why is my MKV not playing in QuickTime Player even on macOS Sequoia?

macOS still does not ship a Matroska container parser. Apple added a Media Extensions framework in Sequoia for third-party format plug-ins, but no first-party MKV extension exists. QuickTime can decode the H.264 or HEVC stream inside the MKV — it just can't read the container that wraps it. Converting to MOV solves this even if you don't re-encode the video.

Can I rewrap MKV to MOV without re-encoding the video?

Yes, if the MKV's video and audio codecs are MOV-compatible (typically H.264 or H.265/HEVC video with AAC or AC3 audio). Use the Copy / passthrough codec option to remux — the video stream is moved into the new container untouched, so there's no quality loss and the conversion finishes in seconds rather than minutes. If the MKV uses VP9, AV1, or FLAC, those need to be transcoded since MOV doesn't officially carry them.

Will my subtitle tracks transfer to MOV?

Partially. MOV's subtitle support is much narrower than MKV's. Soft text subtitles (SRT) can be converted to MOV's text track, but PGS bitmap subtitles from Blu-ray rips and styled ASS/SSA subtitles common in anime do not have MOV equivalents. If you need the subtitles to survive, burn them into the video (hard subs) before converting, or keep an SRT sidecar file next to the MOV.

Should I pick H.264 or H.265/HEVC for the MOV?

H.264 if compatibility matters more than file size — it plays on every Mac, iPhone, iPad, and Windows PC made in the last 15 years. H.265 if you're delivering to modern Apple devices (iPhone 7 and newer, Macs from 2017 / macOS High Sierra onward have hardware HEVC decode) and want roughly half the file size at the same visual quality. For Final Cut Pro editorial, neither is ideal — use ProRes 422 instead.

My MKV is a Blu-ray rip with DTS audio. What happens to it?

MOV does not officially carry DTS. If you select an AAC or AC3 audio codec, the DTS track is transcoded — surround channels are preserved (5.1 stays 5.1) but the audio is re-encoded once. If you need to keep DTS bit-perfect, MKV or M2TS is a better container; MOV is not the right destination.

Why is the MOV file larger than the source MKV?

Two common causes. First, if the MKV was encoded with HEVC and you chose H.264 for the MOV, H.264 needs roughly twice the bitrate for the same visual quality. Either pick H.265/HEVC to match, or use Constant Quality (CRF 18-23) to let the encoder hit a quality target instead of a bitrate target. Second, MOV with PCM audio adds significant size versus MKV with AAC — switch audio to AAC unless you specifically need lossless audio.

Will the conversion preserve HDR metadata for my 4K HDR MKV?

HDR10 static metadata generally survives when you keep HEVC as the codec (copy/passthrough or H.265 encode). Dolby Vision Profile 7 (the dual-layer profile common on UHD Blu-rays) does not survive transcoding to a single-layer MOV — the MOV will play back as HDR10 only. Profile 5 / 8 Dolby Vision is more portable but support varies by playback device.

Can I batch-convert a whole folder of MKVs?

Yes. Queue every file at upload, set codec, resolution, and trim once, and the same settings apply to the whole batch. 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. For very large libraries you might prefer Compress MKV first to reduce upload time, or use MKV to MP4 instead if your target devices also accept MP4 (which most do).

What if I need to go the other direction later?

The reverse conversion is at MOV to MKV — useful if you want MKV's richer subtitle and chapter support for your archival library after editing in Final Cut. For trimming MKV without changing containers, use Trim MKV.
