Free online 3GP to TS converter

Older mobile-phone recordings and MMS attachments may not open in broadcast, IPTV, or editing software that expects MPEG transport stream files. Converting them to .ts makes them usable in those workflows, although incompatible codecs may require re-encoding.

What the 3GP format is

3GP is a compact multimedia container based on the ISO Base Media File Format and developed for third-generation mobile networks. Older phones commonly saved .3gp video with H.263, MPEG-4 Part 2, or H.264 video and AMR-NB, AMR-WB, or AAC audio. The format is still found in phone backups, MMS files, feature-phone recordings, and archived mobile video.

What the TS format is

TS, usually meaning MPEG transport stream, stores packetized audio, video, and metadata for broadcast and continuous transmission. Digital television, IPTV, broadcast ingest systems, and some Blu-ray and editing workflows use it. TS includes timestamps and packet structures designed to help receivers handle transmission errors, but changing the container does not make every 3GP codec compatible with every TS application.

How to convert the file with FFmpeg

FFmpeg is the most flexible desktop option. Install it from ffmpeg.org, open Command Prompt, PowerShell, or a terminal in the folder containing the source file, and inspect the streams if necessary:

ffprobe input.3gp

If the receiving software supports the source codecs, remux the streams without re-encoding:

ffmpeg -i input.3gp -map 0 -c copy -f mpegts output.ts

Remuxing changes the container, so it is fast and does not reduce quality. It may fail or create an unusable file when the 3GP contains AMR, H.263, or another codec that the target TS application does not support.

For broader compatibility, decode the source and encode H.264 video with AAC audio:

ffmpeg -i input.3gp -map 0:v:0 -map 0:a:0? -c:v libx264 -preset medium -crf 23 -c:a aac -b:a 128k -f mpegts output.ts

Replace input.3gp and output.ts with the actual filenames. A lower CRF value such as 18 produces higher quality and larger files; a higher value such as 28 produces smaller files. Omit the optional audio mapping only when the source has no audio or the target requires video alone.

How to convert the file on 101convert

On 101convert.com, select the 3GP file, choose TS as the output format, start the conversion, and download the resulting file. This avoids installing software, but do not upload recordings containing confidential or private material.

Quality and compatibility limits

• Re-encoding cannot restore detail lost in the original low-resolution or low-bitrate 3GP recording.
• H.264/AAC output may be larger than the source because it uses codecs and settings commonly accepted by TS-based software.
• Use remuxing only when the destination supports both the source video and audio codecs; otherwise use the H.264/AAC command.
• TS is a container, not an image-quality upgrade. It does not increase the source resolution, frame rate, or detail.
• Some hardware or broadcast systems require particular frame rates, dimensions, audio codecs, or bitrate limits. Add settings such as -r 25 or -r 30 only when the destination specifies them, because changing frame rate can alter timing and motion.
