How to convert WEBM to 3GP
- Add your .WEBM file - drop it in the box above or click to browse.
- Convert it to .3GP in a few seconds.
- Download your new .3GP file.
What to expect
- The video and audio are fully re-encoded from VP8/VP9/AV1 and Vorbis/Opus into 3GP-compatible codecs (H.263/MPEG-4/H.264 plus AAC or AMR); this is a lossy step, not a straight copy.
- 3GP targets low bandwidth, so resolution and bitrate are typically reduced and the picture may look softer than the WEBM source.
- Container-level metadata and any features specific to WEBM do not carry over into the simpler 3GP structure.
Frequently asked questions
Will the video quality drop when I convert WEBM to 3GP?
Yes. WEBM holds VP8, VP9 or AV1 video, none of which 3GP supports, so the video is re-encoded to H.263, MPEG-4 or H.264. 3GP was designed for low-bandwidth 3G phones, so expect reduced resolution and bitrate.
Why would I convert WEBM to 3GP?
3GP is the container older 3G-era mobile phones and some basic handsets expect. If a device rejects the modern WEBM format, a 3GP file gives you the stripped-down, low-bandwidth profile those phones can play.
Where will the resulting 3GP file open?
3GP is an open 3GPP standard built on the ISO Base Media File Format, and VLC plays it (including AMR audio) on Windows, macOS, Linux, Android and iOS. Older mobile devices that expect 3GP will also play it natively.
What happens to the audio?
WEBM carries Vorbis or Opus audio, which 3GP does not use, so the audio is re-encoded to AAC or the low-bitrate AMR codec. AMR is tuned for speech, so music can sound noticeably worse than the original.
