Does rewrapping MKV as MOV touch the video quality?

For H.264 recordings, no: the stream is copied into the MOV container bit for bit, so the frames you edit are exactly the frames you captured. Only sources in codecs MOV cannot hold are re-encoded, and that is the only case where a lossy generation enters the chain.

My MKV has chapters and subtitle tracks. Do they survive in MOV?

Think of the MOV as a picture-and-sound working copy. MKV's extras (chapter lists, ASS or SRT subtitle tracks, multiple audio languages) come from the Matroska world and do not map one-to-one onto MOV's own track model. Keep the MKV if those elements matter to the project.

Why MOV here rather than MP4?

Because the destination is an Apple editing pipeline. MP4 would also import, but MOV is QuickTime's native container: Finder previews, Quick Look, and Final Cut Pro treat it as the home format. If the file were headed for general distribution instead, MP4 would be the better call.

Is my video uploaded to a server?

No. The whole conversion runs in your browser. Your video is never sent to or stored on a server, so your privacy is preserved.

Can I convert large or long videos?

You can, but because everything runs in your browser, large/long videos and conversions that need re-encoding take time. We recommend files up to around 200MB.

Yes, it is completely free. No sign-up and no installation required.

MKV to MOV converter

Video tools

Convert MKV videos to MOV right in your browser — no upload, no watermark. When the codecs match it's a lossless remux; otherwise it re-encodes locally. Your video never leaves your device.

What is this MKV to MOV converter?

A free, browser-based tool that converts a MKV video to MOV. Add a file, preview it inline, and download the result. All processing happens locally in your browser, so your video is never uploaded and there is no watermark.

Capture on the PC, cut on the Mac: MKV meets MOV

A common creator setup splits the work across machines: the gaming PC or streaming rig records to MKV (OBS's crash-safe default), while the edit happens on a Mac. The snag appears at import: QuickTime does not open MKV, Quick Look stays blank, and Final Cut Pro wants no part of the file.

Rewrapping the recording as MOV removes the friction in one step: previews work in Finder, and the footage drops into the Final Cut timeline without complaint. Nothing about the capture side has to change; the fix happens after recording, not before.

Usually a remux: H.264 passes straight from MKV to MOV

Screen and game captures are overwhelmingly H.264, and MOV holds H.264 natively. That combination makes this conversion a stream copy in most cases: finished in an instant, byte-identical picture, no generational loss before the edit even starts. For footage you are about to spend hours cutting, that is the cheapest insurance available.

Codecs MOV does not accept get re-encoded instead, which adds a lossy generation; if that happens, keep the MKV original alongside the working MOV so you can always return to the capture. Either way, the edit starts from a file the Mac treats as its own.

How to use it

Add a MKV file on the left (drag & drop or click) — it shows an inline preview.
Pick a quality preset (used only when the video has to be re-encoded).
Press “Convert & download” to get your MOV file. The first run downloads the ~30MB converter once.

Lossless remux vs re-encoding

MKV and MOV are containers — what matters is the video codec inside. When the codec already fits MOV, this tool just repackages it (a "remux"): instant and completely lossless. Only when the codec isn't compatible — most often anything involving WebM — does it re-encode the video locally, which takes longer and is where the quality preset applies.
