How to convert WMV to MOV
- Add your WMV file. Drag it onto the box above, click to browse, or paste it from the clipboard. Multiple files are fine.
- Check the target. MOV is preselected. Pick High, Medium or Small quality depending on whether you need a master copy or a small file.
- Download. The conversion engine loads once (32 MB) and then your file is processed locally. The MOV file downloads automatically when it is done.
Why convert WMV to MOV?
WMV files from older cameras and software often will not play or upload where you need them. MOV is what Final Cut, iMovie and QuickTime expect.

What makes this converter different
- Nothing is uploaded. Other converters send your file to a server, queue it, and keep a copy for hours. Here the work happens in your browser with WebAssembly, so private videos, voice memos and documents never leave your computer.
- No limits, no sign-up, no watermark. There is no server to pay for, so there is no reason to cap file size or count.
- Real ffmpeg quality. Video and audio use the same ffmpeg encoders professionals use (x264, LAME, libvpx, FLAC), not a stripped-down web codec.

Frequently asked questions
Is it safe to convert WMV to MOV here?
Yes. The conversion runs entirely inside your browser using WebAssembly. Your file is never uploaded to a server, so nothing can leak, be stored or be seen by anyone. You can even disconnect from the internet after the page loads.
How long does WMV to MOV conversion take?
Video encoding in the browser runs at roughly 0.5–2× real time depending on your CPU and resolution. A 1-minute 1080p clip takes about 1–2 minutes. Long or 4K videos can take a while; a desktop computer is much faster than a phone.
Is there a file size limit?
There is no server-side limit because there is no server. The practical limit is your device memory: browsers can handle files up to about 2 GB. Very large videos work better on a desktop than a phone.
Will the quality drop?
MOV is a lossy format, so a small amount of detail is discarded. At the default Medium setting the difference is invisible or inaudible for almost all content. Choose High for master copies or Small for messaging and web use.
Can I convert several WMV files at once?
Yes. Drop or select as many files as you like; they are converted one after another and each gets its own download button.
