Free online 3GP to OGG converter

Older phones and recording apps often save audio inside .3gp video files, while some Linux, editing, and playback software expects Ogg audio. Converting the file removes the video stream and creates an .ogg file that can be edited, played, or shared where the original container is unsupported.

What the 3GP format is

3GP is a multimedia container based on the ISO Base Media File Format. It was designed for mobile phones, video messaging, and low-bandwidth networks, and was commonly created by older handsets and mobile recording applications.

A .3gp file can contain video encoded with H.263 or H.264 and audio encoded with AMR-NB, AMR-WB, AAC, or another codec. Since OGG is normally used for audio, the conversion usually discards the video and re-encodes the audio stream.

What the OGG format is

OGG is a multimedia container, not a single audio codec. An .ogg file most commonly contains Ogg Vorbis audio; Ogg Opus is also possible, although Opus files commonly use the .opus extension.

Vorbis is an open, lossy audio codec with good general-purpose compression for music and speech. Ogg Vorbis is supported by VLC, many Linux and open-source applications, Firefox, and numerous audio editors, but it is less universally accepted than MP3, AAC, or WAV. Confirm that the destination application supports Ogg Vorbis before converting.

How to convert 3GP to OGG

Using 101convert

1. Open the 3GP-to-OGG converter on 101convert.com.
2. Select or drag the .3gp file into the converter.
3. Choose OGG as the output format and start the conversion.
4. Download the resulting .ogg file when processing is complete.

The built-in converter can be used free without installing desktop software. Do not upload private recordings unless the service's storage and deletion policies are acceptable.

Using FFmpeg

FFmpeg provides control over the output codec and quality. To create Ogg Vorbis audio, run:

ffmpeg -i input.3gp -vn -c:a libvorbis -q:a 5 output.ogg

-vn omits video, libvorbis selects the Vorbis encoder, and -q:a 5 selects variable-quality encoding. The resulting bitrate varies with the audio and is not guaranteed to be a specific kilobit-per-second value. Replace the input and output filenames as needed.

To create Ogg Opus instead, use:

ffmpeg -i input.3gp -vn -c:a libopus -b:a 96k output.ogg

Use a higher bitrate such as 128k for music or a lower setting such as 32k for speech when the receiving application supports Ogg Opus. If FFmpeg reports that libvorbis or libopus is unavailable, install a build containing that encoder.

Quality and compatibility limitations

Audio from 3GP is often already compressed with AMR or AAC. Encoding it again as Vorbis or Opus is a lossy-to-lossy transcode: it cannot restore discarded detail and may add artifacts. Keep the original .3gp file as the archival copy, and avoid repeated conversions.

Inspect the source before converting with:

ffprobe input.3gp

If the file contains no audio stream, an audio-only OGG file cannot be produced. For a file with multiple audio streams, select the first one explicitly:

ffmpeg -i input.3gp -map 0:a:0 -vn -c:a libvorbis -q:a 5 output.ogg

Some software checks the codec rather than accepting every Ogg variant. If it rejects Ogg Vorbis, try Ogg Opus only if supported, or export to WAV or MP3 when those formats are required.
