WTV to 3GP Converter
Processing entirely on your device — large files may take a moment.
Windows TV Recording and 3GPP Mobile Video exist for different jobs: WTV is Windows Media Center's TV recording format — tuner captures with metadata, subtitles and multiple audio tracks inside. Rescuing old phone videos means converting 3GP to MP4 before the memories become unreadable.
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.

About the 3GP format
3GP is the 3GPP mobile video format from the pre-smartphone era, designed for 2G/3G bandwidth: low resolution (typically 176×144 to 640×480), H.263 or baseline H.264 video, and AMR audio. Every early camera phone recorded in it, and MMS messaging depended on its small footprint.
It is strictly a conversion source today: pull the videos off an old phone, convert to MP4, and enjoy a resolution upgrade from better scaling alone. Quality expectations should stay low — the pixels were never there.
+ Strengths
- ✓Tiny files for its era
- ✓Plays on old feature phones
! Limitations
- −Very low resolution and quality ceiling
- −Obsolete; no modern platform wants it

Frequently asked questions
Is this WTV to 3GP 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 3GP?
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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of 3GP, staying in sync with the video. If your WTV file has multiple audio tracks, the first one is used.
Does converting WTV to 3GP 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.
