3GA to MP3 Converter

Upload your recording, and the tool first verifies that the file is a genuine 3GA or 3GPP audio stream. Step one checks file type and size to avoid launching a heavy conversion for unsupported input. Step two lets you choose MP3 bitrate settings from 128 to 320 kbps, depending on whether you prioritize smaller downloads or stronger fidelity. Step three loads FFmpeg WebAssembly and transcodes the source audio with the LAME encoder. Step four produces an MP3 file with a built-in preview player and a direct download button.

3GA files are commonly used by older mobile recorders and often wrap AMR, AAC, or similar streams inside a 3GPP container. During conversion, the container and codec are normalized into standard MP3 so playback works in nearly every media app, editor, and hardware player. Higher MP3 bitrate keeps more detail but increases output size, especially on music recordings.

Practical tip: for speech notes, 128 kbps is usually enough and keeps files compact. For music or ambience where artifacts are easier to hear, use 192 kbps or higher. If conversion fails, try re-exporting the source from your recorder app first. All processing happens locally in your browser. Files are never uploaded to our servers.
