Settings

Select the bitrate range for the Variable Bitrate (VBR) MP3 file. Note that some legacy audio players may display incorrect audio file duration if VBR mode is used, in this case use CBR mode instead.
Set the constant bitrate for the audio track. Leaving this setting to "Auto" will automatically choose a bitrate to achieve a decent quality based on the source audio.
Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

3gp

3GP is a multimedia container format defined by the 3rd Generation Partnership Project as the standard media format for 3G mobile services. Based on the ISO base media file format (MPEG-4 Part 12), it was designed to reduce storage and bandwidth requirements so that mobile phones with limited capabilities could efficiently capture, store, and play video content. The format typically uses H.263 or H.264 video codecs paired with AMR-NB, AMR-WB, or AAC audio. 3GP was instrumental in bringing multimedia to mobile devices during the early smartphone era, when network speeds and device hardware imposed tight constraints on file sizes. The streamlined container strips away overhead found in full MP4 files, resulting in significantly smaller files that stream reliably over slow 3G connections. 3GP supports both GSM and UMTS network protocols and includes provisions for timed text and still images within the container. Broad adoption by major handset manufacturers ensured that practically every 3G-capable phone could handle 3GP media natively. Although modern mobile devices now favor MP4 and other advanced formats, 3GP files are still encountered in archives of older mobile recordings and in regions where bandwidth-efficient video delivery remains important.

mp3

MP3 (MPEG-1 Audio Layer III) is one of the most widely used digital audio encoding formats. It uses a form of lossy data compression to significantly reduce file sizes while retaining near-CD-quality sound, typically achieving a 10:1 compression ratio. Developed by the Fraunhofer Society in collaboration with other digital scientists, the format became an international standard in 1993 as part of the MPEG-1 specification. MP3 files can be encoded at various bit rates, commonly ranging from 128 kbps to 320 kbps, allowing users to balance file size and audio fidelity. The format's efficient compression, broad device compatibility, and small file sizes made it the driving force behind the digital music revolution, enabling practical music storage and distribution over the internet. Today, MP3 remains one of the most universally supported audio formats across virtually all media players, operating systems, and portable devices.

Why should I convert 3GP to MP3?

Extracting MP3 audio from 3GP gives you lightweight, universally playable sound clips for any music player, phone, or portable device.

How can I open MP3 files?

Open MP3 using iTunes, VLC, Windows Media Player, Spotify (local), and every portable music device.

Do I need to install anything?

The converter is completely web-based. No software, no plugins — just open convertio.tools in any modern browser and convert 3GP to MP3 directly.

Will the entire audio track be extracted?

Yes, the converter extracts the entire audio stream from start to finish. The MP3 contains everything heard in the original 3GP recording.

Does converting 3GP to MP3 lose quality?

Quality depends on the bitrate and codec settings you choose. Higher bitrates preserve more detail from the original 3GP audio track.
