Frequently Asked Questions

Why convert FLV to WMV?

WMV plays natively in Windows Media Player without Flash Player or codec packs. It's ideal for Windows environments where FLV would require VLC or a deprecated Flash installation.

What happens to FLV files without Flash Player?

Without Flash Player (discontinued in 2020), FLV files can only be played in third-party players like VLC. Converting to WMV enables native Windows playback.

What FLV video codecs are supported?

FFmpeg handles H.264, H.263, and VP6 video codecs in FLV files, transcoding them to VC-1 in the WMV output.

Is there a file size limit?

Files up to 25MB (free tier; 500MB on Pro) are accepted. For larger FLV files, trim or compress before uploading.

Is my FLV file private during conversion?
