Pick from over a hundred output formats. Filter by category or search by name - every option is open to everyone, no account needed.

03

Convert & download

Hit Convert and grab your download link moments later. Originals are erased when the job completes; results are cleared within about an hour.

What is a 3GPP file?

The 3GPP file extension is functionally identical to 3GP, serving as a simplified version of the MPEG-4 Part 14 (MP4) container format. Designed by the 3rd Generation Partnership Project for GSM networks, it handles data storage for audio, video, and text (subtitles). The format adheres to ETSI 3GPP technical specifications TS 26.244, supporting variable bit rate (VBR) audio via the Adaptive Multi-Rate (AMR) codec. While less common than the three-character .3gp extension, .3gpp is fully compliant with the ISO/IEC 14496-12 standard.

How to open a 3GPP file

Opening a 3GPP file requires software capable of parsing the ISO base media file structure and decoding H.263/H.264 video alongside AMR audio. Native support exists in standard Android video players. For Windows and macOS users, if the default media players (Movies & TV, QuickTime) encounter playback errors, the VLC media player is the industry-standard solution for rendering these mobile-specific archives.

What is a WAV file?

The Waveform Audio File Format (WAV) is a raw audio bitstream standard developed by Microsoft and IBM, serving as a subset of the Resource Interchange File Format (RIFF) specification. It primarily stores uncompressed Linear Pulse Code Modulation (LPCM) audio data, making it the industry standard for archival and high-fidelity mastering on Windows systems. The format supports varying bit depths and sample rates, with the Red Book standard (44.1 kHz, 16-bit stereo) being the most prevalent implementation.

How to open a WAV file

WAV files enjoy near-universal native support across all major operating systems due to their status as a foundational audio standard. Windows Media Player, Apple QuickTime, and Linux-based media players (via ALSA/PulseAudio) open WAV files by default without requiring external codec packs or third-party software.

Developer API

Convert 3GPP to WAV via API

Automate 3GPP to WAV conversions in three steps: create a job, upload your file, then poll for the result.

# 1. Create job
curl -X POST https://api.runconvert.com/v3/jobs \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "tag": "3gpp-to-wav",
    "tasks": {
      "upload-file": {
        "operation": "import/upload"
      },
      "convert": {
        "operation": "convert",
        "input": "upload-file",
        "output_format": "wav"
      },
      "export-result": {
        "operation": "export/url",
        "input": "convert"
      }
    }
  }'

# 2. Upload your file (use upload_url from the response)
curl -X PUT "$UPLOAD_URL" --upload-file input.3gpp

# 3. Poll for result
curl https://api.runconvert.com/v3/jobs/$JOB_ID?include=tasks \
  -H "Authorization: Bearer YOUR_API_KEY"
