AMR to 3GP Conversion FAQ
Why would I convert AMR audio to a 3GP video?
+
A 3GP video plays everywhere a raw AMR sometimes will not — most notably on video-only platforms and social feeds that require a video container. It is the standard way to publish a podcast, song, or mix as a shareable 3GP.
Can I batch-convert many AMR 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.
Is the AMR to 3GP conversion free?
+
Yes, within the free size limit. PRO unlocks much larger AMR uploads, longer durations, and parallel jobs.
How long can the AMR be?
+
Full-length albums and multi-hour AMR recordings convert fine. Because the picture is static, even a long 3GP stays modest in size relative to a filmed video of the same length.
Will the 3GP play on YouTube, Instagram, and TikTok?
+
Yes. PDF.to encodes the 3GP with a widely supported codec and pixel format, so the resulting video uploads cleanly to the major platforms that reject bare AMR audio.
Are my AMR files private during conversion?
+
Yes. Uploads travel over HTTPS, nobody reads the contents, and nothing is shared. Your uploaded AMR and the resulting 3GP are deleted from our servers automatically about 24 hours after the conversion, which leaves time to download the result.
