3GP to WMV Converter

How to Convert 3GP to WMV Online

1. Upload Your 3GP File: Drag and drop or click "Add Files" to select 3GP or 3G2 files. Old Nokia / Sony Ericsson / Motorola phone recordings (2003-2012), MMS attachments, voicemail video clips, and feature-phone camera captures all work. Batch is supported.
2. Pick a Video Codec: Default is WMV2 (Windows Media Video 9) for native Windows Media Player playback. Choose WMV1 for compatibility with very old WMP 7 / 9 builds, MPEG-4 / Xvid for better quality at the same bitrate, or MSMPEG4 for legacy Pocket PC and Windows Mobile devices. Set a quality preset (Highest -> Lowest), target a percentage of the original size, an exact size in MB, or fine-tune with CRF / qscale (1 = highest, 31 = lowest for MPEG-style codecs).
3. Set Resolution and Audio Codec: 3GP source files are typically 176x144 (QCIF) or 320x240 (QVGA) — pick a resolution preset (480p / 720p / Original) or scale by percentage. Default audio is WMA v2; switch to WMA v1 for Windows 98 / Me playback. Trim a clip with start time + duration in HH:MM:SS.sss format to drop the dead lead-in many old phone recordings have.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no 1 GB cap.

Why Convert 3GP to WMV?

3GP (3GPP Multimedia File) was designed for 3G UMTS phones in 2001 and ruled the feature-phone era from roughly 2003 to 2012 — Nokia N-series, Sony Ericsson Walkman phones, BlackBerry, early Motorola RAZR. It uses H.263 or low-profile H.264 video plus AMR-NB audio in a stripped-down MP4 container tuned for 64-128 kbps cellular networks. WMV (Windows Media Video) is Microsoft's container for Windows Media Player, with codecs WMV1, WMV2, and WMV3 / VC-1. Common reasons people convert 3GP -> WMV:

• Windows Media Player compatibility — WMP plays WMV natively without codec packs. 3GP support on Windows requires K-Lite or VLC; many older Windows 7 / 8 boxes refuse to even thumbnail 3GP files in Explorer.
• PowerPoint and Office embedding — Office 2010 / 2013 / 2016 embed WMV cleanly into PowerPoint slides and Word docs. 3GP either fails to embed or shows a broken playback control on the recipient's machine.
• Recovering old phone footage — Wedding videos, kids' first steps, voicemail clips saved off a 2007 Nokia N73 or RAZR V3 — all 3GP. Converting to WMV lets them play in Windows Media Player on family PCs without installing anything.
• Legacy enterprise systems — Surveillance / kiosk / signage software from the Windows XP-Vista-7 era often only ingests WMV or AVI. Converting incoming 3GP from mobile uploads is the cleanest fix.
• Editing in Windows Movie Maker / Movie Maker Live — Movie Maker (the bundled Windows tool through 2017) imports WMV but chokes on 3GP. Converting first lets old phone clips be cut into family slideshows alongside other WMV footage.
• Better compression than H.263 — WMV2 / VC-1 is 30-50% more efficient than the H.263 codec inside most 3GP files, so the WMV usually ends up smaller at the same visual quality.

If you actually want a modern format instead, convert 3GP to MP4 — MP4 with H.264 plays everywhere and isn't deprecated.

Frequently Asked Questions

Why convert 3GP to WMV instead of MP4?

The honest answer: most people shouldn't — MP4 is more universal. But if your target machine is a Windows XP / Vista / 7 PC without modern codecs, an older PowerPoint deck that needs an embedded video, or a legacy kiosk / surveillance system that only accepts WMV or AVI, then WMV is the right call. WMV plays in Windows Media Player with zero setup, while 3GP needs a codec pack.

Will the video quality improve when I convert?

No — and no online tool can fix this. The source 3GP was encoded at 64-256 kbps for 2G / 3G cellular networks at 176x144 or 320x240. Upscaling the resolution doesn't add detail, it just enlarges blurry pixels. The conversion preserves the original quality in a Windows-friendly container. If you want it to look better on a modern screen, run a separate AI upscaler after converting.

What's the difference between WMV1, WMV2, and WMV3?

WMV1 (Windows Media Video 7, 1999) is the oldest and least efficient — bigger files, plays in WMP 7 onward. WMV2 (Windows Media Video 8, 2001) is the most common and what we default to — plays in WMP 9 and every Windows version since XP. WMV3 / VC-1 (Windows Media Video 9, 2003) is the most efficient but requires WMP 10+ and is what's inside HD-DVD and Blu-ray "VC-1" tracks. For broad family-PC playback, WMV2 is the safest pick.

How do I batch convert a folder of old 3GP files at once?

Drop in as many 3GP / 3G2 files as you want — entire folders backed up off old phones work fine. They convert in parallel within your browser session and download individually or as a single ZIP. Settings can be applied uniformly (e.g., one quality preset for all 50 files) or tweaked per-file.

Will the audio survive the conversion?

Yes. 3GP files use AMR-NB (narrowband, 8 kHz, 4.75-12.2 kbps) for voice or AAC-LC for music. We re-encode to WMA v2 by default at a higher bitrate — voice clarity is preserved and music gets a slight boost since WMA is a bigger codec than AMR-NB. If your 3GP is voice-only, the converted WMV will still sound exactly the same as the source; no online tool can recover frequencies that AMR-NB threw away.

Why is my converted WMV bigger than the original 3GP?

3GP files are extremely small because they target cellular bandwidth — a 2-minute clip is often 2-5 MB. WMV at default quality reserves more bitrate for video and audio, so the output may be 8-15 MB. Drop the quality preset to "Low" or set a target file size in MB if you need to match the original 3GP footprint. This is normal — you're trading bitrate for codec compatibility, not the other way around.

Can I trim or cut the 3GP while converting?

Yes. Use the trim section to enter a start time and duration. Both accept seconds (12.5) or HH:MM:SS.sss format (00:00:30.500). Useful for cutting the 1-2 seconds of dead air feature phones often record before the actual footage starts.

Can I play the converted WMV on a Mac or iPhone?

Not natively — macOS and iOS have never shipped WMV codecs (Apple and Microsoft maintain separate codec ecosystems). VLC plays WMV on Mac, but Photos, AirDrop, iMessage, and Safari do not. If your final destination is Apple, convert 3GP to MOV or 3GP to MP4 instead.

Does the converter work for 3G2 files too?

Yes. 3G2 is the CDMA cousin of 3GP — used by Verizon, Sprint, US Cellular, and KDDI au feature phones. The container layout is nearly identical, just with codec preferences tuned for CDMA networks (typically QCELP voice instead of AMR-NB). Drop 3G2 files into the same upload area; they convert to WMV with the same options.
