Free online OGV to 3GPP converter

What the OGV format is

OGV is the video-oriented Ogg container, most commonly carrying Theora video with Vorbis audio. It is used by open-source video tools, older web-video workflows, educational material, and some screen-recording or editing applications. FFmpeg, VLC-based tools, and editors such as Kdenlive can create or export OGV files; Wikimedia and other open-media collections also contain them.

What the 3GPP format is

3GPP is a mobile-media container usually saved with the .3gp extension. It was designed for cellular networks, MMS, and older 3G phones, with common video codecs including H.263, MPEG-4 Part 2, and H.264, and audio codecs including AMR-NB and AAC.

Its compact encoding and broad support on legacy phones are the main reasons to use it. A 3GPP file is not automatically small: the final size depends on resolution, frame rate, codec, and bitrate.

How to convert OGV to 3GPP

For a desktop conversion, FFmpeg provides direct control over the codecs and compatibility settings. Run this command in the folder containing the source file:

ffmpeg -i input.ogv -c:v libx264 -profile:v baseline -level 3.0 -pix_fmt yuv420p -vf "scale=320:-2" -r 15 -c:a aac -b:a 64k -ar 16000 -movflags +faststart output.3gp

This creates a compact 3GPP file with H.264 video and AAC audio. Replace input.ogv and output.3gp with the actual filenames. The scale filter limits the width to 320 pixels while preserving the aspect ratio; remove it or change 320 if the receiving device supports a larger frame.

For an older phone that specifically requires H.263 and AMR-NB, try:

ffmpeg -i input.ogv -c:v h263 -b:v 300k -vf "scale=176:144" -r 12 -c:a amr_nb -b:a 12.2k -ar 8000 output.3gp

That command depends on the encoders included in your FFmpeg build. If FFmpeg reports that amr_nb is unavailable, use the H.264/AAC command or install an FFmpeg build with the required encoder.

Without installing software, upload the file to 101convert.com, choose 3GPP as the output format, and download the converted .3gp file after processing.

Quality and compatibility limitations

OGV-to-3GPP conversion requires decoding Theora and Vorbis and re-encoding both streams, so it is normally lossy. Keep the original OGV as an archive and use a higher video bitrate when image quality matters.

Older devices may reject H.264/AAC even though the file uses a 3GPP container; H.263 with AMR-NB is generally the safer legacy combination. Use conservative dimensions such as 176x144 or 320x240, a low frame rate, and filenames ending in .3gp. Test the result on the target phone or player because 3GPP codec support varies by model.
