Frequently Asked Questions

WMV is natively supported on Windows without requiring Apple's QuickTime software. It's the preferred format for Windows Media Player, legacy Windows apps, and corporate Windows environments.

Can I play the WMV file on my Mac?

WMV playback on Mac requires a third-party player like VLC or Microsoft's deprecated Silverlight plugin. For cross-platform use, MP4 is a better choice.

Converting between compressed formats involves some quality loss from re-encoding. ChangeThisFile uses FFmpeg's high-quality WMV encoding settings to minimize visible differences.

How large can the MOV file be?

The maximum upload size is 50MB. Larger MOV files should be compressed or split before uploading.

Is the conversion private?

Yes. Your MOV file is uploaded over HTTPS encryption, converted on isolated servers, and deleted immediately after your download. Nothing is retained.

What audio does the WMV output use?

The output WMV uses Windows Media Audio (WMA) encoding, which plays natively in Windows Media Player and Windows systems without additional codecs.

Does this work with iPhone MOV videos?

Yes. MOV files captured on iPhone (which use H.264 or H.265) are supported. Make sure the file is within the 50MB size limit.
