WTV to TTA Converter
Processing entirely on your device — large files may take a moment.
Windows TV Recording and True Audio exist for different jobs: WTV is Windows Media Center's TV recording format — tuner captures with metadata, subtitles and multiple audio tracks inside. Convert TTA to FLAC or MP3 for everyday playback.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

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.
+ Strengths
- ✓Complete tuner captures with subtitles
- ✓Multi-language audio preserved
- ✓ffmpeg decodes natively
! Limitations
- −DVR-MS (older) is a different format
- −Broadcast DRM variants exist
- −Copy-once flags block some captures
About the TTA format
TTA (True Audio) is a no-frills real-time lossless compressor: simple 32-bit crypto-free checksums, multi-threadable encoding and IDs at both frame and file level. It filled the lossless niche on slow connections and in Russian archive communities where FLAC arrived late.
Decoding is near-instant and lossless, so converting TTA to FLAC or MP3 costs nothing in fidelity — the audio is identical, the compatibility is finally universal.
+ Strengths
- ✓Real-time speed on modest hardware
- ✓Simple, well-documented container
- ✓Error-tolerant frame structure
! Limitations
- −Compression ratios behind modern codecs
- −Ecosystem largely inactive
- −Tagging support is weak

Frequently asked questions
Is this WTV to TTA 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 TTA?
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.
Does converting WTV to TTA re-encode my video?
Yes. The video is decoded and re-encoded with the settings chosen by the quality slider, which is what allows the format and size to change. For an archival copy, keep higher quality; for sharing, lower quality gives a much smaller file.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of TTA, staying in sync with the video. If your WTV file has multiple audio tracks, the first one is used.
