Need help?Convert 3G2 to APNG Online
Turn an old 3G2 mobile clip into an animated PNG that keeps full 24-bit color and a real alpha channel — the two things a GIF throws away. 3G2 is the CDMA-era container (3GPP2, ~2004) that Verizon and other CDMA phones recorded to, so the footage is usually short, low-resolution, and a good fit for a looping animation. Pick your output framerate, cap the resolution, and download a lossless-frame APNG with no sign-up and no watermark.
How to Convert 3G2 to APNG
- Upload Your 3G2 File: Drag and drop your
.3g2(or.3gp) onto the page, or click Upload to browse. The file is sent over an encrypted connection. - Set the Framerate: Choose the output frame rate from the Framerate dropdown — 10 FPS is the recommended default and keeps the file small; raise it toward 20-30 FPS for smoother motion at the cost of size.
- Adjust Image Quality, Image Resolution, and Colors (Optional): Use Image quality (%) and the Image resolution presets (or a width x height with aspect ratio kept) to control sharpness and pixel size; leave Colors on ORIGINAL for full color, or switch to By Color Reduction + Dither to shrink the file.
- Convert and Download: Click Convert. Frames are extracted, assembled into an APNG, and optimized — then your file is ready to download. No sign-up, no watermark.
APNG vs GIF vs Animated WebP
| Property | APNG | GIF | Animated WebP |
|---|---|---|---|
| Color depth | 24-bit (16.7M colors) | 256 colors per frame | 24-bit |
| Transparency | Full 8-bit alpha | 1-bit (on/off) | Full 8-bit alpha |
| Frame compression | Lossless | Lossless (palette) | Lossy or lossless |
| Typical file size | Larger than GIF at equal quality | Small but banded | Smallest of the three |
| Fallback in old viewers | Shows first frame as static PNG | Universally shown | May not render |
| Native browser support | Chrome 59+, Edge 79+, Firefox 3+, Safari 8+ (~94.7% globally) | Universal | Chrome, Edge, Firefox, Safari 16+ |
| Best for | Crisp short loops needing real transparency | Maximum compatibility, simple loops | Smallest web-delivered animation |
For maximum reach or a smaller file you may prefer 3G2 to GIF; if you just want the clip playable again rather than as a loop, convert 3G2 to MP4 instead.
Frequently Asked Questions
Why convert an old 3G2 file to APNG instead of MP4?
3G2 is a CDMA-network video container from the mid-2000s, so the clips tend to be a few seconds long at a small resolution — exactly the kind of footage that works better as a self-playing loop than a video file. An APNG plays inline anywhere an image can (a chat thread, a README, a forum post, an email) without a media player or codec, and unlike MP4 it carries a transparent background if you need one. If you instead want a normal, scrubbable video you can share or re-edit, convert 3G2 to MP4.
Does APNG keep transparency that GIF loses?
Yes. APNG carries a full 8-bit alpha channel, so semi-transparent pixels, anti-aliased edges, soft shadows, and glows stay smooth. GIF only has 1-bit transparency — each pixel is either fully visible or fully transparent — which produces the jagged "halo" outline you see when a clip is placed over a colored background. Most 3G2 footage is fully opaque camera video, so this only matters if your source already has an alpha channel; for plain recordings the bigger win is APNG's 24-bit color over GIF's 256-color palette.
Why is my APNG larger than a GIF would be?
APNG stores lossless frames with full 24-bit color and a real alpha channel, so it does not throw away color data the way GIF's 256-color palette does. That fidelity costs bytes. In our testing, a 6-second 176x144 (QCIF) 3G2 clip exported as APNG at 10 FPS came out larger than the same clip as a 256-color GIF. To shrink it, lower the Framerate, cap the Image resolution, drop Image quality (%), or switch Colors to By Color Reduction + Dither — and if size matters more than fidelity, convert to 3G2 to GIF instead.
What framerate should I pick for a 3G2 clip?
10 FPS (the default) is a good balance for short loops and keeps the file manageable. Old 3G2 video was often captured at 15 FPS or lower to begin with, so there is no benefit to setting the output above the source rate — you would just be duplicating frames and inflating the file. Bump it to 20-30 FPS only if your specific clip was recorded at a higher rate and the motion looks choppy at 10.
Will the APNG play everywhere?
APNG renders natively in Chrome 59+, Edge 79+, Firefox 3+, and Safari 8+ — about 94.7% of browsers worldwide per caniuse. Anything that does not understand the animation simply shows the first frame as a normal static PNG, so it degrades gracefully rather than breaking. That first-frame fallback is part of the APNG specification.
Is my uploaded 3G2 file kept private?
Your file is uploaded over a TLS-encrypted connection, converted on our servers, and automatically deleted after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
