Need help?JPG to 3G2 Converter
3G2 (the 3GPP2 file format) is the small, legacy video container built for CDMA mobile phones, so a JPG cannot simply be "renamed" into one — it has to be wrapped in a video stream. This tool takes a still JPG and holds it on screen for a duration you choose, encoding that single frame into a playable 3G2 clip with no motion and no audio. It is useful when an old or basic device, a CDMA-era handset, or a system that only accepts 3GPP2 video needs a picture delivered as a tiny video file.

How to Convert JPG to 3G2
- Upload Your JPG File: Drag and drop your image onto the page or click "+ Add Files" to select one or more JPG, JPEG, or JFIF files.
- Set the Image Duration: Pick how long the still frame plays from the Duration dropdown (the default is 5 seconds per frame). This sets the length of the resulting 3G2 clip.
- Choose Merge Strategy and Background: Use "Merge images" to combine several pictures into one clip or "Video per image" for a separate file each; set a Background Color (default Black) to fill any area the image does not cover, and pick a Quality Preset or Fixed Resolution if needed.
- Convert and Download: Click "Convert" and download your 3G2 file. No sign-up, no watermark.
Frequently Asked Questions
Why would I turn a JPG into a 3G2 video instead of just sending the image?
3G2 exists for situations where a target device or system only accepts 3GPP2 video, not still images. A basic or legacy CDMA-era handset, an old multimedia-messaging pipeline, or a kiosk that plays only mobile video may reject a JPG outright but accept a short 3G2 clip. Wrapping the picture in a 3G2 lets it pass through as a tiny, low-bandwidth video.
Will the 3G2 file have any motion or sound?
No. The conversion holds your single JPG on screen for the duration you set, so every frame is identical — there is no motion — and no audio track is added. The result is a still image presented as a video for the length of time you chose.
What video codec does the 3G2 output use?
The 3GPP2 container supports H.263, MPEG-4 Part 2, and H.264/AVC video. xconvert encodes a baseline-compatible stream so the clip stays small and plays on devices that expect standard 3GPP2 video, which is the whole reason to use the format rather than a modern container.
How is 3G2 different from 3GP?
Both are built on the same ISO base media file format (MPEG-4 Part 12), but 3GP was defined by 3GPP for GSM-based phones (.3gp) while 3G2 was defined by 3GPP2 for CDMA-based phones (.3g2). 3G2 is designed to consume less space and bandwidth and drops a few of the newer audio codecs 3GP allows, such as HE-AAC v2 and AMR-WB+. If your device is a GSM-era phone, you may want JPG to 3GP instead.
What controls the size of the 3G2 file?
Three things: the Duration you choose (a longer clip stores more frames), the resolution (keeping the original versus picking a smaller Fixed Resolution), and the Quality Preset. Because 3G2 was built for narrow mobile bandwidth, even a multi-second clip from one image typically stays very small. In our testing, a single 1920x1080 JPG held for 5 seconds produced a 3G2 file well under 1 MB at the default quality.
Can I combine several JPGs into one 3G2 clip?
Yes. Upload multiple images and choose "Merge images" as the Merge strategy; each picture plays for the duration you set, in upload order, inside a single 3G2 file. Choose "Video per image" instead if you want each JPG exported as its own separate 3G2 clip.
Do modern phones still play 3G2 files?
Most current smartphones no longer record 3G2, but desktop players such as VLC and QuickTime open them, and the format remains relevant when you specifically need compatibility with older CDMA handsets or systems standardized on 3GPP2 video. For everyday playback on a modern device, converting to 3G2 to MP4 is the more practical direction.
Are my uploaded files kept private?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
