Add your 3GP file
Drop one or more .3gp files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
Pulling the soundtrack out of a .3gp video into .wav audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.
Batch files can each use a different output. Nothing uploads for local conversions.
Working inputs include camera RAW, browser-local audio/video, PDF, CBZ/CBR comics, office documents, ebooks, markup, 3D models, structured text, images, and archives.Pulling the soundtrack out of a .3gp video into .wav audio keeps what you can hear and drops the picture entirely. A .3gp file is a lightweight container defined by the 3GPP standards body for video recorded and shared on mobile phones. It packs low-bitrate video and compressed speech with minimal overhead, which made .3gp the format of MMS messages and early camera phones.
A .wav file is Microsoft's Waveform Audio format, which in practice almost always stores uncompressed PCM samples. Because every bit of the original signal is preserved and no decoding is required, .wav remains the default working format in recording studios and audio editors. For this route the practical draw is bit-perfect with zero generation loss and negligible CPU cost to read or write — balanced against enormous compared with FLAC, which halves the size losslessly, which is worth knowing before you commit a large batch.
The usual reason to take .wav audio out of a .3gp file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, picture quality is poor by any modern standard; on the target side, the payoff is bit-perfect with zero generation loss, which is exactly what you want for capturing and mixing sessions in a DAW.
| Aspect | 3GPP video (.3gp) | WAV audio (.wav) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Lossless — every pixel or sample is preserved exactly |
| How it stores data | iSO base media structure like MP4, but with a deliberately restricted codec list | a RIFF chunk container whose fmt chunk usually declares linear PCM, though compressed codecs are technically permitted |
| Strongest at | recovering videos from old feature phones and their memory cards | capturing and mixing sessions in a DAW |
| Weak spot | picture quality is poor by any modern standard | enormous compared with FLAC, which halves the size losslessly |
| Metadata | a small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them | rIFF INFO chunks hold basic tags, while the Broadcast Wave bext chunk and iXML add description, originator, and timecode for production workflows; some tools also embed ID3 chunks |

Select .wav in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if WAV is selectable, the route is real and validated.
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid WAV file. Outputs keep the original filename with the .wav extension.
Since 3gp is container-oriented and wav is lossless-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .wav itself requires.
Yes — the .3gp file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Windows, macOS, Linux, iOS, Android, and all major browsers play .wav natively. Recordings that exceed 4 GB require the RF64 variant, which some consumer software fails to recognize.
Much smaller — the video stream is usually 80–95% of a .3gp file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, a small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them; none of it is transmitted anywhere because the file never leaves your browser.
