Is this MKV to MOV converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple MKV files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

How large can my video files be?

Free accounts support files up to 10 MB — enough for short clips and GIFs. Pro raises that to 500 MB, which covers most 1080p videos. For files over 1 GB, a native app like HandBrake will be faster.

Will the video lose quality during conversion?

When only the container changes (e.g., MKV → MP4 where both use H.264), there's zero quality loss — it's a lossless rewrap. When the codec changes, we encode at CRF 23, which is near-transparent for most content.

Why does Final Cut Pro prefer MOV over MKV?

Final Cut Pro is an Apple product and is optimised for the QuickTime MOV container, which is Apple's native video format. While FCP can import some MKV files, MOV imports reliably without compatibility issues.

Is MKV to MOV conversion lossless?

If the video codec in the MKV (typically H.264 or H.265) is compatible with MOV, the converter can remux — changing only the container without re-encoding — which preserves exact quality.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert MKV to MOV?

MKV is the container of choice for media servers like Plex, Jellyfin, and Kodi — but the same file that plays perfectly on your home server is completely invisible to Apple's creative tools. Final Cut Pro cannot import MKV. iMovie does not support it. QuickTime Player cannot open it without third-party software. If you want to edit a film, a Blu-ray rip, or a downloaded video in an Apple application, you need to move it out of the MKV container first.

MOV is Apple's native container format. It is the default output of every Apple camera, the expected input for every Apple video editing application, and the format that QuickTime Player was built around. Final Cut Pro and iMovie open MOV files instantly — no plugins, no codec packages, no configuration. Apple silicon Macs have hardware acceleration for the codecs most commonly found in MOV files.

Converting MKV to MOV re-encodes the video inside a QuickTime container that Apple tools can immediately use. MKV files often carry high-quality H.264 or H.265 video — if you re-encode to H.264 or HEVC in a MOV container, you can preserve most of that quality with minimal loss. MKV files with multiple audio tracks will use the default track in the output MOV. This is the standard workflow for bringing Plex-sourced or downloaded video content into Final Cut Pro for editing.

Quality & file size: MKV to MOV

Typical file sizes: MKV 200–800 MB → MOV 150–500 MB.

Both MKV and MOV use lossy compression. We transcode at high quality settings (equivalent to MOV's recommended web quality) to minimize generational loss.

Color depth: MKV supports standard color, MOV supports standard color.

Transparency: MKV does not support transparency. MOV does not support transparency — transparent areas become solid white.
