Need help?DNG to 3G2 Converter
DNG (Adobe Digital Negative) is a raw still-photo format — a single frame straight off a camera sensor. 3G2 (3GPP2) is a video container built for old CDMA-network mobile phones. So this is not a normal image conversion: it wraps your one raw photo into a short, silent video clip that simply holds that single picture on screen for a few seconds. The image does not move or animate, and 3G2 carries no audio in this mode.
If you instead want a viewable picture, convert to a still image with DNG to JPG. If you want a clip you can actually share today, DNG to MP4 is far more universal than 3G2.
DNG Format at a Glance
| Property | Value |
|---|---|
| Type | Raw still image (one photo) |

| Released | 2004 (built on TIFF 6.0) |
| Latest spec | 1.7.1.0 (September 2023) |
| Bit depth | 8 to 32 bits/sample, integer or floating point |
| Holds | Unprocessed sensor data + EXIF, plus full editing latitude |
| Best for | Archival, raw editing, recovering highlights/shadows |
3G2 Format at a Glance
| Property | Value |
|---|---|
| Type | Video container (silent here, since the source is one image) |
| Standard | 3GPP2, based on ISO/IEC 14496-12 (MPEG-4 Part 12) |
| Released | January 2004 |
| Video codecs | H.263, MPEG-4 Part 2, H.264 (xconvert outputs H.264 by default) |
| Audio codecs | AMR, AAC, QCELP/EVRC family (not used for an image source) |
| Designed for | CDMA2000 phones (Verizon / Sprint era); development has stagnated |
| Best for | Legacy CDMA handsets; for anything modern, prefer MP4 |
How to Convert DNG to 3G2
- Upload Your DNG File: Drag and drop your .dng file or click "+ Add Files." You can queue several photos, and "Video per image" creates one clip per file.
- Set Image Duration: Under Advanced Options, use the "Duration" dropdown to choose how long the still is shown (1/60s up to 10 seconds per frame).
- Pick Background Color and Resolution: Choose a "Background Color" for any letterboxed area, and set the video resolution (keep original or a fixed preset); the "Quality Preset" defaults to Very High.
- Convert and Download: Click "Convert" to get your 3G2 file. No sign-up, no watermark.
Frequently Asked Questions
Why does my DNG photo become a silent video instead of an image?
3G2 is a video container, not an image format, so there is no way to store a bare photo in it. The converter renders your raw frame to a fixed picture and writes a short clip that displays it. Because the source is a single image, the output has no audio track. If you only want a picture, convert to DNG to JPG instead.
Will I lose image quality going from DNG to 3G2?
Yes, substantially. DNG holds wide-latitude raw data at up to 32 bits per sample, while 3G2 is an 8-bit, small-resolution mobile format. The conversion flattens that tonal range and scales the picture down to a size old CDMA phones could play, so highlight and shadow detail is discarded. Keep the original DNG if you ever want to re-edit.
What devices and players actually open a 3G2 file?
3G2 was made for CDMA2000 handsets from the Verizon/Sprint era. On a computer, QuickTime and most general media players (such as VLC) open it on Windows, macOS, and Linux. Modern phones and web browsers often will not play 3G2 directly, which is why MP4 is the safer choice for sharing.
Should I convert DNG to 3G2 or to MP4?
Choose 3G2 only if a specific legacy CDMA device requires it. For almost every other purpose — phones, social apps, browsers, modern players — DNG to MP4 with H.264 is more compatible and usually smaller at the same visual quality. 3G2 development has effectively stalled, so it is a compatibility format, not a quality one.
Does the converter preserve my DNG's metadata in the 3G2 file?
No. EXIF fields such as camera model, lens, and capture settings live in the still-image layer of the DNG and are not carried into a 3G2 video stream. If you need that metadata intact, convert to a still format like JPG or keep the DNG, since the raw file remains your archival master.
Is my DNG file kept private during conversion?
Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. In our testing, a single 24-megapixel DNG rendered to a 10-second 3G2 clip finishes in a few seconds on a normal broadband connection.
