Supports: 3GPP
This converter turns a .3gpp (or .3gp) mobile clip into a .wmv Windows Media Video file. Be clear up front about what this is: both formats are legacy. A 3GP file is a feature-phone-era container the 3rd Generation Partnership Project built for early 3G handsets; WMV is Microsoft's Windows Media-era format. Converting one to the other is not a modernization — it is a lossy-to-lossy re-encode between two old formats. Pick WMV only when a specific Windows-Media workflow demands it. If you want a file that plays on phones, browsers, and modern editors, the right target is 3GPP to MP4, not WMV.
| Property | 3GPP (.3gpp /.3gp) | WMV (.wmv) |
|---|---|---|
| Defined by | 3rd Generation Partnership Project (3GPP) | Microsoft (Windows Media) |
| Era | Early 2000s, GSM/UMTS 3G mobile | Late 1990s-2000s, Windows Media |
| Container | ISO BMFF (ISO/IEC 14496-12) | Advanced Systems Format (ASF) |
| Video codecs | H.263, MPEG-4 Part 2, later H.264/AVC | WMV 1 / WMV 2 (this tool); WMV 9 = VC-1 |
| Audio codecs | AMR-NB, AMR-WB, AAC | Windows Media Audio (WMA) |
| Typical resolution | 176x144 (QCIF) or 352x288 (CIF) | Whatever the source carries (no upscale gain) |
| File size | Very small, built for cellular links | Larger; WMV 2 is less efficient than H.264 |
| Native playback in 2026 | VLC, MX Player, older Android | Windows Media Player on Windows; VLC elsewhere |
| Best for | Old MMS / feature-phone recordings | Legacy Windows-only / WMP / old PowerPoint workflows |
Neither format is a good long-term home for footage in 2026. The comparison above exists to settle one decision: is your destination a Windows-Media tool (choose WMV) or anything modern (choose MP4)?

Leave Quality Preset on "Very High (Recommended)", or under File Compression switch to Constant Bitrate, Variable Bitrate, or Specific file size to hit a target..wmv file. No sign-up, no watermark.For almost every modern use, choose MP4. Both 3GP and WMV are legacy formats, but WMV's playback support outside Windows is patchy and its default WMV 2 codec is older and less efficient than the H.264 inside an MP4. Convert to WMV only when a specific Windows-Media workflow needs it — an old Windows Media Player or Movie Maker project, a Windows-only application, or a legacy PowerPoint that embeds .wmv clips natively. If you just want a file that plays everywhere, use 3GPP to MP4 instead.
No — and that is an honest limit, not a tool flaw. 3GPP recordings from feature-phone-era handsets are typically 176x144 (QCIF) or 352x288 (CIF), so that detail simply is not in the source. Going 3GP to WMV is a lossy-to-lossy re-encode that cannot add back detail the original already discarded, and WMV 2 is a less efficient codec than the H.264 the clip might otherwise use. A small low-res 3GP stays small and low-res; choosing a larger resolution preset enlarges the frame but invents no new detail. Keep "Keep original" resolution for the most honest output.
The Video Codec defaults to WMV 2, the FourCC for Windows Media Video 8, and the Audio Codec to WMA v2 (Windows Media Audio) — the standard pairing inside a .wmv file, which is itself an ASF (Advanced Systems Format) container. Under the Video Codec menu you can switch to WMV 1 (Windows Media Video 7) if an older target requires it. These are distinct from WMV 9, which Microsoft submitted to SMPTE and which was standardized in 2006 as SMPTE 421M, better known as VC-1.
Most 3GPP recordings carry AMR-NB (narrowband) or AMR-WB (wideband) audio — voice codecs built for cellular calls — though some later clips use AAC. A WMV file normally carries Windows Media Audio, so whatever your source track is, it gets re-encoded to WMA v2 by default. That re-encode is lossy, so pick a generous preset to keep speech clean. If the converted clip plays but has no sound, the source most likely had no audio track or an AMR stream that failed to decode.
Legacy versions of Microsoft PowerPoint on Windows embed and play Windows Media (.wmv) clips natively, because both are Microsoft formats sharing the same Windows Media codecs, so a WMV drops in without prompting for an external codec. Newer PowerPoint (2013 and later) and the Mac versions handle MP4/H.264 directly, so for a current deck convert to 3GPP to MP4 instead.
Yes, that is expected. WMV is a Windows Media format with poor native support outside Windows — iOS, Android, and most browsers do not play it without VLC or a third-party app. In our testing, a 176x144 AMR-audio .3gpp clip converted at the "Very High" preset opened cleanly in Windows Media Player and in VLC on every desktop, but would not play in mobile Safari or Chrome. If you need playback on phones, browsers, or social uploads, convert to MP4 instead; for the bare .3gp flavor of the same source see 3GP to MP4.
Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
