Supports: 3GP, 3G2
3GP is the 3GPP mobile-phone container from the early camera-phone era; OGV is the Xiph.Org Ogg video container, almost always carrying the royalty-free Theora codec. People reach for this conversion to get an open, patent-free file for Linux tooling, MediaWiki, or an open-source pipeline. Be aware up front: OGV/Theora is now a legacy format, and for most people WebM or MP4 is the better target. Convert to OGV only when a tool specifically requires Ogg/Theora.

.3gp (or .3g2) clip onto the page, or click "+ Add Files." You can queue several clips and convert them with the same settings.Probably not. Chrome disabled Theora by default in version 120 and Chromium removed the codec in 123 (March 2024), Edge followed in version 122, Firefox disabled it by default in version 126, and Safari never supported Ogg/Theora at all. A Theora-based OGV no longer plays in a current desktop browser. If you need browser playback, convert to WebM or MP4 instead.
Not inherently. Both Theora and 3GP's H.263/MPEG-4 are older lossy codecs. Re-encoding a low-resolution 3GP into OGV cannot recover detail the original never captured — at best it preserves what is already there. In our testing, a 320×240 3GP re-encoded to OGV looked the same as the source, just in a different container; you do not gain sharpness by converting.
The Theora I bitstream was frozen in June 2004 and has never been revised, and browsers began switching the decoder off over security exposure and near-zero usage: Chrome disabled it by default in version 120 and removed the code in 123, and Firefox disabled it by default in 126. The reference library is still maintained — libtheora 1.2.0 shipped in March 2025 — but that does not bring browser playback back, and the open-web community moved to WebM (VP9, then AV1), which compresses better and is broadly supported.
Yes. The AMR or AAC audio in your 3GP is re-encoded into the OGV — by default to Vorbis, the codec normally paired with Theora in Ogg. You can also choose Opus or FLAC in the Audio Codec menu if your target tool prefers them.
That is the tension with OGV: it is royalty-free but barely plays in browsers anymore. WebM with VP9 or AV1 is also royalty-free and has wide modern support, so it is usually the better open-format choice. Pick OGV only when a specific tool requires Ogg/Theora.
Close enough that both work the same way here. .3gp is the 3GPP container from GSM-network phones, and .3g2 is the 3GPP2 variant from the CDMA side; both are ISO base-media files carrying mobile-era codecs, differing mainly in which audio codecs they favor. This converter accepts either .3gp or .3g2 and re-encodes the video and audio into your chosen OGV codecs, so you don't need to know which flavor your old phone produced.
Vorbis is the classic pairing with Theora inside an Ogg file and is the safe default — if a tool asks specifically for "Ogg/Theora with Vorbis," that's the combination to keep. Opus is a newer, more efficient codec that Ogg also supports and is a good pick when your target software accepts it. FLAC is lossless but noticeably larger and only worth it if you specifically need lossless audio. Since a 3GP source carries low-bitrate AMR or AAC to begin with, Vorbis or Opus at a modest bitrate is plenty.
VLC, mpv, and most open-source media players handle OGV directly, but no current browser does — Firefox disabled Theora by default in version 126, and Chromium removed it in 123. On Windows and macOS the default players often will not open it either, which is another reason most users convert their 3GP clips to MP4 or WebM instead.
