Follow these simple steps to convert your file in seconds.
Choose a AVI file
Select or drop one file up to 100 MB. Its extension must match this converter. Availability is checked before transfer.
Convert to WMV
Video is re-encoded using the selected output’s defaults. Image quality, audio and metadata can change. Check playback and duration in the application where you will use it.

Use Download after conversion completes. Open the result and check its content, quality and formatting before sharing it. Download links expire one hour after upload finishes. Uploaded and converted files are removed automatically by regular cleanup. Files may become unavailable sooner when the service restarts.
Tips for Converting AVI to WMV
Practical advice to get the best results from this conversion.
Why this conversion is worth doing
AVI Video has a known limitation: no native support for variable frame rate or modern streaming features. WMV Video addresses this with a key advantage: good compression efficiency, especially at low bitrates. Converting from AVI to WMV is most worthwhile when this specific trade-off matters for the way you intend to use the file.
Match the format to the actual workflow
AVI Video is most commonly used for legacy video file storage and archival, while WMV Video is the standard for legacy windows video libraries and media collections. If your workflow is closer to the second pattern, converting makes sense. If you are still working in a context where AVI is the norm, converting may create unnecessary compatibility friction with collaborators or tools that expect the source format.
Watch for this limitation in the WMV output
WMV Video has its own limitation worth understanding before you commit: proprietary format with poor cross-platform compatibility. After the conversion completes, open the WMV file and verify that this limitation does not affect your specific use case — for some workflows it is irrelevant; for others it can be a deal-breaker.
Avoid transcoding unless necessary
Every time you transcode (re-encode) a video, some quality is lost unless you use a lossless codec. If you only need to change the container format without changing the codec, use a remux (stream copy) operation instead of a full re-encode. This preserves original quality and is much faster.
Understanding AVI and WMV Formats
Learn about the source and target file formats to understand what happens during conversion.
Source Format
AVI Video
video/x-msvideoAVI (Audio Video Interleave) is a multimedia container format introduced by Microsoft in 1992 as part of the Video for Windows framework. It stores video and audio data interleaved together and supports a wide variety of codecs. While AVI is a mature and widely supported format, it lacks many features found in modern containers such as native streaming support and variable frame rates.
Advantages
- Very wide compatibility with both old and new media players
- Simple container structure that is easy to process
- Supports virtually any video and audio codec combination
Limitations
- No native support for variable frame rate or modern streaming features
- Poor subtitle and metadata support compared to MKV or MP4
- Older container design lacks advanced features like chapters
Common Uses
- Legacy video file storage and archival
- Video capture from older software and hardware
- Simple video editing and offline playback
Target Format
WMV Video
video/x-ms-wmvWMV (Windows Media Video) is a proprietary video compression format developed by Microsoft, based on the Advanced Systems Format (ASF) container. It was designed for streaming and local playback on Windows platforms and includes built-in DRM support for content protection. WMV has largely been superseded by H.264/MP4 for most modern use cases.
Advantages
- Good compression efficiency, especially at low bitrates
- Native support in Windows Media Player and Windows ecosystem
- Built-in DRM support for protected content distribution
Limitations
- Proprietary format with poor cross-platform compatibility
- Not supported on iOS, many Android players, or web browsers without plugins
- Declining usage and relevance in modern video workflows
Common Uses
- Legacy Windows video libraries and media collections
- DRM-protected video content from older platforms
- Windows-based screen recordings and presentations
