Quick answer: To convert SVI to WMV, add the SVI file to the iHateFiles SVI 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. SVI is a format most software has stopped opening. WMV is not.
Should you convert SVI to WMV?
Yes. SVI is a format most current software no longer opens, so converting it is the reliable way to keep watching it. WMV is a reasonable target; MP4 is the safest.
The picture is re-encoded
An SVI usually holds MPEG-4 or H.263 video from an old Samsung phone. This writes Windows Media (MS-MPEG4) video with WMA sound into the WMV. Both sides are compressed with loss, so this is a second generation: leave the quality at its default or higher, because the encoder is working from SVI artefacts rather than the original.
Where the WMV will play
WMV plays on Windows, and VLC elsewhere; Macs need an extra player.
SVI and WMV side by side
| SVI | WMV | |
|---|---|---|
| Inside the file | MPEG-4 or H.263 video from an old Samsung phone | Windows Media (MS-MPEG4) video with WMA sound |
| Compression | Lossy | Lossy |
| Carries sound | Yes | Yes |
| Plays on | Needs converting first | Windows, and VLC elsewhere; Macs need an extra player |
| Here | Read only | Read and write |
What usually goes wrong
About the SVI. Renaming .svi to .3gp often works, since that is essentially what it is.
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 SVI to WMV
- Add your SVI 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 SVI to WMV?
Open this page, add your SVI 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 SVI 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 SVI files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
