Fast, secure 3GP to TS conversion. No registration required.
Here is the short version — 3GP is the mobile video container standardised by 3GPP for early smartphones. Hence the need for TS. A 3GP to TS conversion rescues a clip that refuses to play somewhere important — a phone, a smart TV, a web uploader. KaijuConverter uses FFmpeg under the hood, the same engine video professionals rely on, and prioritises stream-copy over re-encode so the output stays faithful to the source. Background. 3GP is the mobile video container standardised by 3GPP for early smartphones. Destination side, TS is the MPEG transport stream, used in broadcast and HLS streaming segments.
3GPP Video
Source format3GP is a multimedia container designed for 3G mobile phones. It stores video and audio at low bitrates optimized for limited bandwidth. Many early mobile phone recordings use this format.
MPEG Transport Stream
Target formatTS (Transport Stream) is used for broadcasting, streaming, and recording live TV.
Why convert 3GP to TS
The usual reason to convert from 3GP into TS is the same reason anyone transcodes video: the original container is not accepted where you are trying to send the file. Swapping to TS flips that rejection into a clean upload without altering the footage itself.
HOW TO CONVERT
3GP → TS
Provide the 3GP clip
Upload through the browser; transfers are encrypted end-to-end and files are quarantined per session.
Convert to TS
The conversion keeps resolution, frame rate and bit depth identical to the source unless you explicitly override them.
Save to your device
Click download to pull the TS to local storage; share the short-lived URL with collaborators if needed.
Common Use Cases
Share across platforms
Send TS files to anyone without worrying about whether they have the right software for 3GP.
Embed in documents
Drop TS output into Word, Google Docs, PowerPoint, Notion or a website without conversion warnings.
Optimize size
TS often produces smaller files than 3GP for web, email and storage.
Archive & future-proof
Store in a widely-supported format that will still open on future operating systems without legacy plugins.
3GP vs TS — Strengths and limitations
What each format does best, and where it falls short.
3GP Strengths
- Extremely low bitrate and file size — great for 2G/3G networks.
- Universal playback in feature phones and early smartphones.
- Based on MP4 — easy to convert and handle with modern tools.
- Mandatory codec in every 3G device since 2001.
Limitations
- Tiny resolutions — rarely above 320×240 in practice.
- H.263 video is far behind H.264 in compression efficiency.
- Metadata support is minimal.
TS Strengths
- Designed for noisy channels — packet-level error correction.
- Multi-program: one TS can carry several TV channels.
- Native format for all digital TV broadcasts and HLS streaming.
- Streaming-first: no need to download whole file to start playing.
- 30+ years of stable, deployed infrastructure.
Limitations
- Packet overhead (~3% vs Program Stream).
- Seek index is implicit — requires scanning for random access.
- Multiple audio/subtitle selection requires parsing PMT (Program Map Tables).

3GP vs TS — Typical file sizes
Approximate file sizes for common scenarios.
3GP
- 1-min MMS video (176×144) 300-800 KB
- 5-min phone clip (320×240) 5-15 MB
TS
- HLS video segment (6 seconds, 1080p) 2-5 MB
- 1 hour recorded TV (HD) 4-8 GB
- Satellite transponder capture (1 min) ~300 MB
Quality & Compatibility
The conversion does not upscale or sharpen the video. A 1080p 3GP produces a 1080p TS; a 4K source stays 4K unless you select a lower output resolution explicitly. Picking higher bitrates does not improve perceived quality beyond the source ceiling.
Tips for Best Results
- If your 3GP has variable frame rate, force a constant frame rate in TS to avoid stuttering on some players and streaming platforms.
- For screen recordings at high resolution, quality 22 CRF H.264 keeps text perfectly readable at a fraction of the source size.
- Check the audio track after transcoding — some 3GP containers carry unusual audio codecs that downgrade subtly when remapped to TS.
Frequently Asked Questions
Only when it has to. If the codecs inside 3GP (usually H.264 or H.265 for video, AAC for audio) are accepted by TS, we stream-copy — the bytes are repackaged into the new container with zero re-encoding and no quality loss. When the source uses a codec the target does not support, we transcode at a matching bitrate to keep the visual quality close to the original.
With stream copy, expect the job to finish in seconds to tens of seconds regardless of video length — the work is mostly rewriting the container. Transcoding is slower (roughly real-time: a ten-minute clip takes about ten minutes) because every frame must be decoded and re-encoded. The progress bar shows which mode applies.
Yes. Resolution, frame rate, colour space and bit depth are preserved by default; stream copy is literally bit-identical on these parameters. If you explicitly pick a lower bitrate or a different codec in Advanced, the output is rebuilt to those settings, but the default is always "match the source".
