About 3GP and AAC

3GP is the legacy mobile format; MP4 keeps the same content and plays everywhere.

AAC is the audio codec used by most streaming services.

3GP files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • Only the first audio stream is used.

Frequently asked questions

How do I convert a 3GP file to AAC?

Add your 3GP file to the box above. convertexa detects the format from the file content, applies the 3GP to AAC conversion and gives you the result to download. The whole operation runs inside your browser.

Are my 3GP files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the 3GP to AAC conversion lossless?

No. AAC is a re-encoded format, so some data is discarded to reach the target format. 3GP is the legacy mobile format; MP4 keeps the same content and plays everywhere.

Is there a size limit?

For reliable results keep the input under 300 MB. Very large files run out of memory in the browser rather than failing quietly.

Which browsers are supported?

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
