Is this WMV 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 WMV 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 can't Macs open WMV files without extra software?

WMV requires Windows Media Player or a third-party codec. Apple removed QuickTime's WMV support, and WMV is not natively supported in macOS. Converting to MOV (H.264) makes it immediately playable in QuickTime and editable in iMovie.

Will the MOV output play on older Macs as well as new ones?

Yes — H.264 MOV is supported on all macOS versions from Snow Leopard onwards and by all versions of QuickTime Player, iMovie, and Final Cut Pro.

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 WMV to MOV?

WMV files are invisible to Apple's creative tools. Final Cut Pro does not import WMV. iMovie cannot open it. QuickTime Player on macOS requires additional codec installations that Apple does not provide. If you receive a recorded presentation, webinar, or training video in WMV format and want to edit it on a Mac, you are immediately blocked by the format incompatibility.

MOV is the native container for Apple's entire creative ecosystem. Final Cut Pro, iMovie, QuickTime Player, and Motion all open MOV files without any plugins or special handling. The QuickTime container is what Apple-based video workflows are built around, and it supports the H.264 and HEVC codecs that Mac hardware is optimized to decode.

Converting WMV to MOV decodes the Windows Media Video and WMA audio tracks and re-encodes them inside a QuickTime container. The video is typically encoded as H.264, which Final Cut Pro and iMovie handle natively. This is a lossy re-encoding process — quality depends on the bitrate settings used and the quality of the original WMV. For presentations and screen recordings where the original quality was modest to begin with, the difference is usually negligible. The output will open immediately in every Mac video application without any additional software.

Quality & file size: WMV to MOV

Typical file sizes: WMV 50–150 MB → MOV 150–500 MB.

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

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

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