Convert AVI to WMV — Free & Private
WMV is the native format for Windows Media Player and is required by SharePoint libraries, corporate video platforms, and PowerPoint embeds that reject AVI. Converting AVI to WMV produces a VC-1 encoded file that streams natively on any Windows machine without codec packs, and embeds cleanly into Office presentations and Windows Media Center libraries.

Key Questions About AVI to WMV, Answered
Direct answers structured for AI extraction, voice search, and featured snippets.
Will my video be re-encoded or just remuxed when converting AVI to WMV?
Re-encoded. WMV containers expect Microsoft's VC-1 or WMV3 video codecs, and AVI files — whether they hold DivX, Xvid, or H.264 — use none of these. Convertlo transcodes the video into a Windows Media-compatible codec, which is a full re-encode rather than a quick remux.
- Every AVI → WMV conversion requires re-encoding, regardless of the original AVI codec
- Output targets broad compatibility with older Windows Media Player installs
- If you mainly need modern compatibility, MP4 (H.264) is supported just as widely today and re-encodes faster
Will the output WMV play in Windows Media Player and VLC?
Yes — WMV is built for Windows Media Player, and VLC, Plex, and most third-party players on Windows handle it without extra codecs. Outside Windows, support is patchier: macOS, iOS, and most browsers don't open WMV natively.
- Windows Media Player and VLC: native WMV playback
- macOS, iOS, Android, browsers: no native WMV support — VLC or a converter is needed
- If the file needs to play on non-Windows devices too, MP4 is the better target
How much will the file size change going from AVI to WMV?
Similar to converting to MP4. WMV's video codec is roughly comparable in efficiency to H.264, so an old DivX/Xvid AVI typically shrinks substantially — though usually not quite as dramatically as a VP9 WebM conversion would.
- DivX/Xvid AVI → WMV: typically 2–6x smaller at comparable quality
- The reduction comes from replacing an old, inefficient codec — not from the WMV container itself
- For maximum compression, VP9 (WebM) or H.265 (MP4/MKV) outperform WMV's codec
When does AVI-to-WMV actually make sense instead of converting to MP4?
Rarely — but WMV is the right choice for embedding video in a PowerPoint presentation or delivering to a Windows-only intranet where VC-1 is the expected codec. For any other use case, MP4 is the better target.
- PowerPoint video embed on Windows: WMV plays without extra codecs on every Windows version
- Windows-only SharePoint or LMS that requires WMV specifically: WMV is the correct choice here
- Anywhere else — phones, web, Mac, social platforms: use MP4, as WMV won't play on iOS or in browsers

Frequently Asked Questions
People Also Ask
What is the difference between AVI and WMV?
AVI (Audio Video Interleave) was created by Microsoft in 1992 as a container format — it can hold many different video codecs inside one wrapper: DivX, Xvid, H.264, or even uncompressed video. WMV (Windows Media Video) is a compressed video format using Microsoft's VC-1 codec, designed specifically for Windows delivery. AVI files are often large because they depend on whatever codec was used to encode them, which varies widely. WMV uses purpose-built compression, so a 2 GB AVI typically converts to a 300–600 MB WMV at comparable quality.
Is WMV better quality than AVI?
Quality depends on the codec used, not the container. An AVI encoded with H.264 at high bitrate will look better than a low-bitrate WMV. At matched bitrates, modern codecs like H.264 outperform WMV's older VC-1 compression. For everyday use — home videos, screen recordings, business presentations — WMV quality is perfectly acceptable while producing files 50–70% smaller than typical unoptimised AVI files using DivX or Xvid codecs.
How do I convert AVI to WMV without losing quality?
All re-encoding between lossy formats involves some quality loss — the original was already compressed once. The key is using high WMV quality settings so the re-compression adds minimal visible degradation. Use the converter above with default high-quality settings. For archival purposes, keep the original AVI and use the WMV only for sharing. If quality is the top priority, converting AVI to MP4 with H.264 produces smaller files with better quality than WMV at the same bitrate.
Can I convert AVI to WMV on a Mac?
Yes — this converter runs entirely in your browser, so it works on Mac, Windows, or Linux without installing anything. The resulting WMV file will play on Windows via Windows Media Player. On Mac, WMV files need VLC or another third-party player. If you are converting for Mac playback, MP4 with H.264 is a more practical target format than WMV, since it plays natively on all Apple devices without extra software.
Why convert AVI to WMV instead of MP4?
The main reasons are Windows-specific workflows: embedding video in older PowerPoint presentations (some versions handle WMV more reliably than MP4), sharing with users who only have Windows Media Player, legacy kiosk or presentation systems from the Windows Vista and 7 era that pre-date MP4 support, or meeting storage standards on Windows archive systems where WMV is the established format. For general-purpose sharing or web use, MP4 with H.264 is the better choice over WMV in most situations today.
