Why can't this tool convert GIF to WMV directly in the browser?

WMV uses Microsoft's proprietary VC-1 and WMV9 codecs. No browser JavaScript API can encode to these formats — the WebCodecs API and MediaRecorder only support open codecs like H.264, VP8, and VP9. FFmpeg, which runs locally on your machine, is the correct tool for GIF-to-WMV conversion. This tool generates the exact command for you.

Which WMV codec version should I choose?

WMV8 (wmv2) is recommended for the best balance of quality and compatibility — it plays on Windows Media Player from XP through Windows 11. WMV7 (wmv1) offers the broadest legacy support. WMV9 (wmv3) delivers the highest quality but requires VC-1 decoder support, which some older players lack.

How do I install FFmpeg to run the generated command?

On Windows: run "winget install ffmpeg" in PowerShell, or download a build from ffmpeg.org/download.html. On macOS: run "brew install ffmpeg". On Ubuntu/Debian Linux: run "sudo apt install ffmpeg". Verify with "ffmpeg -version".

Will the WMV output loop like the original GIF?

No. WMV is a standard video file and does not loop automatically. For looping playback in Windows Media Player, use the built-in repeat option. For web use, an HTML video tag with the loop attribute is more efficient.

Is my GIF file uploaded anywhere?

No. The GIF analyzer reads your file entirely in your browser using the FileReader API. Your file data never leaves your device. The FFmpeg command is also generated locally — no server is involved.

What bitrate should I use for GIF to WMV?

For most GIF animations (which are typically under 640×480), 1500–3000 kbps produces excellent quality. For larger GIFs (720p or above), use 4000–6000 kbps. GIFs have limited color depth (256 colors), so very high bitrates beyond 8000 kbps give diminishing returns.

Why in-browser GIF to WMV is not possible

WMV uses Microsoft's proprietary VC-1 / WMV9 codec. Browser APIs (WebCodecs, MediaRecorder) only support open codecs — H.264, VP8, VP9, AV1. No JavaScript library can legally encode to WMV. FFmpeg, which is free and open-source, runs entirely on your local machine and handles this conversion in seconds. Your GIF never leaves your device.

How to install FFmpeg

Windows

winget install ffmpeg

Or download a build from ffmpeg.org/download.html

macOS

brew install ffmpeg

Ubuntu / Debian Linux

sudo apt install ffmpeg

Verify install: ffmpeg -version
