MP3 to 3GP Transformation FAQ
Can I batch-convert a whole album of MP3 files to 3GP?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Are my MP3 files private during the 3GP conversion?
+
Yes. Uploaded MP3 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted 3GP are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
