- Upload Your FLV Files: Click "+ Add Files" to select FLV files from your computer, Google Drive, or Dropbox.

Optionally change video codec, audio codec, or resolution (preset like 1080p/720p, percentage, or custom width×height).
- Convert and Download: Click "Convert" and download your WMV files.
Why Convert FLV to WMV?
Both FLV and WMV are legacy formats, but they serve different ecosystems:
- FLV (Flash Video) — Adobe's web video format, used extensively from 2005-2015. Flash was officially discontinued on December 31, 2020. No modern browser plays FLV.
- WMV (Windows Media Video) — Microsoft's video format. Plays natively in Windows Media Player without additional codecs.
Converting FLV to WMV makes sense if you need to play old Flash videos on Windows computers using Windows Media Player.
FLV vs WMV vs Modern Formats
Competitors like aconvert.com offer bitrate, aspect ratio, frame size, and frame rate controls for FLV-to-WMV conversion. convertfiles.com explains that FLV uses Sorenson Spark or VP6 codecs while WMV uses Microsoft's proprietary codecs. convertio.co provides VBR/CBR quality modes. XConvert adds video/audio codec selection, 6 compression methods (quality preset, target file size %, CRF), and resolution control.

Frequently Asked Questions
Is it free?
Yes. Completely free with no watermarks, no sign-up required, and no file count limits.
Should I convert to WMV or MP4?
If you only need Windows Media Player playback, WMV works. For universal compatibility across all devices and browsers, MP4 is the better choice.
Can I convert multiple files at once?
Yes. Upload multiple FLV files and convert them all with the same settings.
Will the quality be the same?
Quality depends on the original FLV file. FLV files from the Flash era were often low-resolution (360p-480p). Converting doesn't improve the original quality.
Does it work on mobile?
Yes. Works in any modern browser on all devices — no app installation required.
