Frequently asked questions
Why convert 3GP to WAV?
Old phone videos in 3GP stutter in modern players and social media. Converting to MP4 preserves those 2008 memories in a format that still opens. WAV is the WORKING format: lossless editing, accepted by every audio software, and what telephony/IVR systems usually require (8 kHz mono WAV).
Where do 3GP files come from?
Typically from pre-smartphone cell phones (Nokia, Sony Ericsson, Motorola), old MMS and feature phones still in use. Derived from MP4 for 3G networks (3GPP); tiny video (176×144 was common) with AMR audio — the low quality comes from the original, not the conversion. The .3g2 is the variant for CDMA networks (3GPP2).
Is it worth using WAV?
WAV is the WORKING format: lossless editing, accepted by every audio software, and what telephony/IVR systems usually require (8 kHz mono WAV). Microsoft/IBM RIFF container (1991); 16-bit/44.1 kHz stereo is 10.1 MB/min; RIFF has a 4 GB ceiling — longer recordings use W64 or RF64.
Do I lose quality when converting 3GP to WAV?
There is no additional loss: the WAV preserves exactly what exists in the 3GP file. Keep in mind that the original quality of the 3GP (which is already compressed) is the ceiling — converting to a lossless format does not "recover" quality.
What if I need a transcript of this audio?
After converting, you can transcribe the file with AI on VoxScriber: 30 free minutes per month, with automatic punctuation and speaker identification. Ideal for WhatsApp audio messages, meetings, and interviews.
Is my file sent to any server?
No. All processing is local (FFmpeg compiled to WebAssembly running on the page). The file never leaves your device—it even works offline after the page loads.
Is there a size or quantity limit?
The limit is 500 MB per file (browser memory). There is no limit on the number of uses. For larger files, VoxScriber processes them on the server with uploads up to 5 GB.

Convert 3GP to MP3
MP3 is the format that opens on ANY device made since the 1990s — the safe choice for sharing, attaching to email, and playing on your car stereo.
Convert 3GP to M4A
AAC delivers the same quality as MP3 with about 30% less space — it's MP3's technical successor and the Apple ecosystem standard.
Convert 3GP to OGG
OGG compresses well with high quality and is an open, royalty-free format—great for web and games.
Convert MP3 to WAV
Leaving MP3 usually means needing WAV to edit without accumulating loss (recompressing MP3 degrades every generation) or a format required by a specific system — IVR/telephony wants 8 kHz WAV, iPhone ringtones want M4R.
Convert M4A to WAV
Older stereos, car radios, and some corporate systems won't open M4A — an iPhone voice memo arrives and no one can play it.
Convert M4B to WAV
M4B features (chapters, resume-where-you-left-off) only work in Apple apps and dedicated readers — many players won't even open the file.
