How do I convert a WMV file to MP4 using LetsConvert?

Upload your WMV file, select MP4 as the output format, choose video and audio settings like resolution and bitrate, then click Convert. Once processing completes, download your new MP4 file, which is ready for playback on all modern devices.

Why should I convert WMV to MP4 instead of keeping the original WMV file?

WMV is a legacy format designed for Windows Media Player, often resulting in larger files and limited support on non-Windows devices. MP4 uses H.264/HEVC compression, which reduces file size by up to 50% while maintaining quality, and is universally supported by iOS, Android, macOS, smart TVs, and web browsers.

Does the conversion preserve the original video quality and metadata?

Unless you choose lossless encoding, the conversion re-encodes video to H.264, which may slightly alter color accuracy and audio bitrate depending on selected settings. We preserve the original resolution, frame rate, and any embedded metadata like title and creation date, but recommend using a high bitrate (e.g., 8-10 Mbps for 1080p) to minimize generation loss. Audio is re-encoded to AAC, so bitrate and sample rate can be customized.

Yes, WMV-TO-MP4 on LetsConvert is 100% free with no registration or hidden fees required.

Yes! WMV-TO-MP4 works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?
