WMV to TGZ Converter
Processing entirely on your device — large files may take a moment.
Windows Media Video and Gzipped TAR (TGZ) exist for different jobs: WMV is Microsoft’s Windows Media video format, still found in old recordings, webinars and screen captures. Convert TGZ exactly like TAR.GZ — unpack, repack or inspect.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How WMV compares to TGZ
| WMV | TGZ | |
|---|---|---|

| Best for | Legacy Windows media | Source releases and backups |

About the WMV format
WMV (Windows Media Video) is Microsoft's codec family, most commonly WMV3/VC-1 inside an ASF container. In its Silverlight-era heyday it delivered good quality at dial-up-to-DSL bitrates and DRM for Windows Media services. Today it survives mainly in corporate archives, old training videos and PowerPoint embeds from the 2000s.
Non-Windows playback was always its weakness and remains so: macOS and Linux need workarounds, phones and web platforms ignore it. Converting WMV to MP4 is the standard exit, and usually saves space at the same time.
+Strengths
- ✓Good quality-per-bit for its era
- ✓Native Windows Media integration
!Limitations
- −Poor non-Windows and mobile support
- −Obsolete next to H.264
- −DRM variants are device-locked
About the TGZ format
TAR.GZ is the classic Unix distribution shape: a TAR bundle squeezed through gzip (DEFLATE-based). Every Linux package of source code, every Apache tarball, every data-science dataset arrives this way. Decompression is a pipeline — untar the gzip stream — and the format is understood everywhere Unix ideas went.
gzip compresses the whole archive as one stream, which keeps ratio decent for text-heavy trees but means reaching file #400 requires decompressing the previous 399. Modern alternatives (zstd) are faster at similar ratios, yet tar.gz remains the safest common denominator.
+Strengths
- ✓Universally understood on Unix-like systems
- ✓Good ratio for text and source trees
- ✓Preserves Unix permissions via TAR
!Limitations
- −Single stream — no random access
- −Slower than modern zstd
- −Two-step format (tar + gzip)
Why convert WMV to TGZ?
There is a concrete reason this conversion exists: Poor non-Windows and mobile support TGZ sidesteps that — Universally understood on Unix-like systems If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this WMV to TGZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WMV to TGZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Why is video conversion slower than image conversion?
Every frame has to be decoded and re-encoded. This site runs that work on your own CPU via WebAssembly — nothing is uploaded, but a multi-minute video reasonably takes a few minutes. Images, by comparison, are single-frame jobs.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of TGZ, staying in sync with the video. If your WMV file has multiple audio tracks, the first one is used.
