3GP to W64 Converter
Processing entirely on your device — large files may take a moment.
3GPP Mobile Video and Sony Wave64 exist for different jobs: 3GP is the ultra-compressed video format old feature phones used. Modern players often cannot open these recordings. Convert W64 recordings to WAV or FLAC for standard editors.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

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
About the W64 format
W64 is Sony's Wave64 — what happens when WAV's 32-bit size fields run out of road. A RIFF variant with 64-bit offsets, it shrugs off the 4 GB ceiling that makes plain WAV choke, which is why long field-recording sessions and Sony Vegas projects land in W64.
Inside, it is the same uncompressed PCM as WAV — ffmpeg hands W64 to WAV, FLAC or MP3 without touching a single sample, so conversion is purely about container compatibility.
+ Strengths
- ✓No 4 GB size ceiling — hours-long recordings
- ✓Bit-exact PCM, same as WAV inside
- ✓Standard in Sony Vegas workflows
! Limitations
- −Almost nothing outside Sony tools opens it
- −Uncompressed — very large files
- −Legacy niche — new tools prefer RF64
Why convert 3GP to W64?
Think of it as moving your file to the container that fits the job. Very low resolution and quality ceiling W64 works differently: No 4 GB size ceiling — hours-long recordings If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this 3GP to W64 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 3GP to W64?
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.
Does converting 3GP to W64 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.
Will the audio track be kept?
Yes. The audio is carried over and re-encoded to the standard audio codec of W64, staying in sync with the video. If your 3GP file has multiple audio tracks, the first one is used.
