3GP is a compact 3GPP container used by early mobile phones, commonly with H.263 or H.264 video and AMR or AAC audio.
What this converter actually supports
Convertr uses the deployed FFmpeg toolchain for published audio and video routes. A container such as MP4, MOV, MKV, AVI, or WebM can hold different codecs, so the file extension alone does not guarantee that a particular player will accept the contents.
MP4 is normally the practical output for archiving and sharing 3GP recordings on current devices.
The public upload limit is 1 GB. Convertr does not reduce dimensions, duration, resolution, or output quality merely to manage worker load.
Quality and format limits
Keep the original dimensions and frame rate unless you intentionally need a smaller result. Remuxing compatible streams avoids re-encoding; changing codecs is lossy, so repeated conversions should be avoided.
Low-resolution phone footage cannot gain missing detail during conversion.
Published 3GP inputs

Published 3GP outputs
Choose one of these implemented routes; a listed extension is not a promise that every codec variant will decode.
Check that the file opens in its original application, is not encrypted or DRM-protected, and really matches its extension. A damaged header, unsupported internal codec, missing linked asset, or mislabeled file can fail even when 3GP is generally supported. Try a different published target only when it fits your goal; changing the extension by hand does not convert the file.
