WTV to WIM Converter
Processing entirely on your device — large files may take a moment.
Extracting WIM to ZIP exposes the files inside Windows images without deployment tools. If your files are still in WTV format, this page is the shortcut: WTV is Windows Media Center's TV recording format — tuner captures with metadata, subtitles and multiple audio tracks inside.
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.

About the WTV format
WTV is Windows Media Center's recording format — what a tuner card wrote when you scheduled a TV show. Inside sits the broadcast transport stream (MPEG-2 or H.264) plus title metadata, subtitle tracks and multiple audio languages, all wrapped in Microsoft's own container.
Media Center died with Windows 10, but the recordings live on: ffmpeg reads WTV natively, so converting to MP4 or MKV keeps the content playable on any device with the metadata you actually care about.

- ✓Multi-language audio preserved
- ✓ffmpeg decodes natively
!Limitations
- −DVR-MS (older) is a different format

- −Copy-once flags block some captures
About the WIM format
WIM (Windows Imaging Format) is how Microsoft ships Windows itself: the install media and deployment images are WIM files, holding a complete filesystem snapshot with single-instancing (identical files stored once). It is Windows' answer to tar — file-based rather than sector-based.
Opening one without deployment tooling (DISM, 7-Zip on Windows) is awkward. Extracting WIM to ZIP exposes the files inside — drivers, scripts, provisioned apps — on any system, no Windows required.
+Strengths
- ✓Windows' native image format
- ✓Single-instancing deduplicates identical files
!Limitations
- −Opaque without Microsoft tooling
- −Files inside may be Windows-locked

Frequently asked questions
Is this WTV to WIM 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 WTV to WIM?
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 WIM, staying in sync with the video. If your WTV file has multiple audio tracks, the first one is used.
