Need help?JPEG to 3G2 Converter
JPEG (JPG) is a still photo; 3G2 (3GPP2) is a video container built for old CDMA cellphones. This tool wraps your single JPEG into a short 3G2 clip by holding the one frame on screen for a duration you choose — there is no motion and no audio, just a still picture encoded as a tiny mobile-format video. You would only need this for a legacy CDMA handset, an old MMS-style workflow, or software that insists on a 3G2 input.

3G2 (3GPP2) Format at a Glance
| Property | Value |
|---|---|
| Standard | 3GPP2 C.S0050, on the ISO base media file format (ISO/IEC 14496-12, MPEG-4 Part 12) |
| Initial release | January 2004 |
| Designed for | 3G CDMA2000 mobile phones (less storage, less bandwidth) |
| Extensions | .3g2, .3gp2, .3gpp2 |
| MIME type | video/3gpp2 |
| Video codecs | H.263, MPEG-4 Part 2, and H.264/AVC |
| Audio codecs | AMR-NB, AMR-WB, AAC-LC, plus CDMA codecs EVRC / QCELP / SMV |
| Sibling format | 3GP — the 3GPP version for GSM/UMTS phones |
3G2 and 3GP are near-identical containers; the split is which cellular family they targeted. 3G2 was made for CDMA2000 networks, and the major US CDMA networks have since shut down (Verizon retired its CDMA network at the end of 2022), so a fresh 3G2 file is rarely needed today. When you do need one, H.264 video gives the widest playback, while H.263 maximizes compatibility with the oldest handsets. Because the source is a still photo, the output carries no audio track.
How to Convert JPEG to 3G2
- Upload Your JPEG File: Drag and drop your JPG or JPEG onto the page, or click "+ Add Files." You can add several stills at once.
- Set the Duration: Use the "Duration" control to choose how long the still is held on screen — the default is 5 seconds per frame, adjustable from a single frame up to 10 seconds.
- Pick Background Color and Quality Preset (Optional): "Background Color" (default White) fills any gaps if the frame is padded to fit; "Quality Preset" (default Very High) sets the encode quality. The video codec defaults to H.264.
- Convert and Download: Click "Convert" to get your 3G2 file. No sign-up, no watermark. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion.
Frequently Asked Questions
Will the 3G2 file have sound?
No. The source is a single JPEG still image with no audio, so the resulting 3G2 has a video track only. 3G2 itself can carry AMR or AAC audio, but there is nothing to encode from a photo — the clip is silent by design.
Why is my 3G2 just a frozen image instead of a moving video?
That is expected. A JPEG is one frame, so the converter shows that single picture for the duration you set (5 seconds by default). There is no animation or panning — it is a still held on screen, then encoded as a short 3G2 clip. If you want motion, you would need multiple images or an actual video source.
Which video codec does the 3G2 output use?
H.264/AVC by default, which is the most broadly playable codec the 3G2 container supports. The format also allows H.263 and MPEG-4 Part 2; H.263 is the safest choice for very old CDMA handsets, while H.264 is best for anything newer.
What is the difference between 3G2 and 3GP for my JPEG?
They are almost the same container built on MPEG-4 Part 12. 3G2 (3GPP2) targeted CDMA2000 phones; 3GP (3GPP) targeted GSM/UMTS phones. For a still image either works, so pick the one your device or software expects. To produce the GSM variant instead, use JPEG to 3GP.
Is 3G2 still worth using in 2026?
Rarely. It was designed for 3G CDMA phones, and those networks have largely been shut down, so most people are better served by a modern container. Convert to 3G2 only when a specific legacy device or program requires it; otherwise JPEG to MP4 produces a far more compatible clip from the same photo.
Can I turn several JPEGs into one 3G2 slideshow?
Yes. Upload multiple files and choose "Merge images" to combine them into a single 3G2, with each still shown for the duration you set. Pick "Video per image" instead to get a separate 3G2 file for every photo. In our testing, three 1080p JPEGs at the default 5-second duration produced a single 15-second 3G2 clip.
How do I open or play a 3G2 file on a computer?
Desktop players such as VLC play 3G2 directly. If you need to edit or share it more widely, convert it back with 3G2 to MP4, since MP4 plays on virtually every modern phone, browser, and editor.
Will my photo be cropped or padded to fit the 3G2 frame?
Padded, not cropped. The picture is scaled to fit the output frame, and if its aspect ratio doesn't match, the leftover area is filled with the Background Color you choose (White by default) rather than trimming the image edges. So a wide landscape photo placed in a squarer mobile frame gets bars around it instead of losing its sides. If you would rather avoid the bars, pick an output resolution whose shape matches your photo's aspect ratio.
