Why Convert JFIF to 3G2?
JFIF (JPEG File Interchange Format) is the standard JPEG image format. 3G2 (3GPP2) is a mobile video container designed for CDMA phones and low-bandwidth networks. Converting JFIF images to 3G2 creates mobile-optimized video slideshows that play on feature phones, can be sent via MMS, and transfer quickly over slow connections — useful when you need to share photo content as video on basic mobile devices.
JFIF vs 3G2
| Feature | JFIF (image) | 3G2 (video output) |
|---|---|---|
| Type | Still image | Mobile video |
| Developer | JPEG committee | 3GPP2 |
| Primary use | Photos, web images | CDMA mobile phones |
| File size | ~100–500 KB | ~50–200 KB per second |

Use Cases
- MMS video messages — Create 3G2 video slideshows from JFIF photos for sending as MMS video messages on CDMA networks.
- Feature phone content — Convert photos to 3G2 video for playback on basic phones that handle video better than image galleries.
- Low-bandwidth sharing — 3G2 is optimized for slow connections. Convert photos to compact 3G2 video for sharing over 2G/3G networks.
- Photo slideshows for mobile — Combine multiple JFIF photos into a single 3G2 video slideshow for easy mobile viewing.
Does this accept JPG and JPEG files too?
Yes. The converter accepts JFIF, JPG, and JPEG files — they are all the same JPEG image format with different file extensions.
How long will each image display?
You control this with the Image Duration setting. Options range from 1/60s to 10 seconds per image.
Can I merge multiple photos into one video?
Yes. Select "Merge images" under Merge Strategy. All uploaded images are combined into a single 3G2 video in upload order.
What is 3G2?
3G2 (3GPP2) is a multimedia container format developed for CDMA mobile networks (Verizon, Sprint). It is based on the MP4 format but optimized for smaller file sizes and lower bandwidth.
Can I set a background color?
Yes. Under Background Color, choose from Black (default), White, and other colors. This fills the space around images that don't match the output resolution.
