Batch Settings
Quality reduction ahead
WAV is uncompressed, meaning every bit of data is preserved. 3GP uses lossy compression — some data is permanently discarded to reduce file size. At high quality settings the difference is usually imperceptible, but the original data cannot be recovered.
Some metadata may not survive
Your WAV file may contain RIFF chunks, BWF metadata metadata. 3GP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
3GP lossy compression can produce heavy blockiness (extreme compression). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
