Quick answer: To convert AVI to WMV, add the AVI file to the iHateFiles AVI to WMV converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. Re-encodes the picture and sound into a WMV container.
Should you convert AVI to WMV?
A safe conversion: AVI and WMV are both lossless, so this is a change of container rather than a change to the picture.
Nothing is discarded
AVI and WMV are both lossless, so every pixel survives the move intact. Convert back and forth as often as you like; the image does not degrade.

What usually goes wrong
About the AVI. Audio drifting out of sync partway through an AVI is common, because the container assumes a fixed frame rate that the source did not actually have. Re-encoding to MP4 corrects the timing.
About the WMV. A WMV that will not play anywhere may be DRM-protected rather than corrupt. No converter can remove that, and none should.
How to convert AVI to WMV
- Add your AVI file. It is read from your disk and stays there.
- Check the settings. The output format is already set to WMV.
- Press convert and the WMV file is saved back to your device.
Questions
How do I convert AVI to WMV?
Open this page, add your AVI file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this AVI to WMV converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to WMV lose quality?
WMV is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several AVI files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
