Convert 3GP to APNG Online

Convert 3GP to APNG Online

3GP is the low-bitrate video container that old 3G phones and basic camcorders recorded to, so most 3GP clips are short and small to begin with. Turning one into an APNG (animated PNG) gives you a single looping image that drops anywhere a PNG works — chat threads, docs, wikis, README files — while keeping lossless frames, 24-bit color, and smooth 8-bit alpha transparency that a GIF cannot match.

How to Convert 3GP to APNG

1. Upload Your 3GP File: Drag and drop your .3gp or .3g2 clip onto the page, or click "Upload" to pick it from your device. The file is sent over an encrypted connection and deleted from our servers automatically after a few hours.
2. Set the Framerate: Open the options and choose a value under "FRAMERATE" — 10 FPS is the recommended default and keeps the APNG small. Raise it toward 15-25 FPS for smoother motion at the cost of more frames and a larger file.
3. Adjust Image Quality, Resolution, and Colors (Optional): Use "Image quality (%)" to trade size for fidelity, "Image resolution" (a percentage, a width/height in pixels, or a preset) to shrink the canvas, and "Colors" to keep the original 24-bit palette or apply color reduction with dither for a smaller output.
4. Convert and Download: Click "Convert" and save your APNG. No sign-up, no watermark.

APNG vs GIF vs Animated WebP

Frequently Asked Questions

Why is my APNG larger than the original 3GP?

3GP uses inter-frame video compression (each frame is stored as the difference from the last), while APNG stores frames losslessly. A short 3GP can therefore expand into a much bigger APNG. In our testing, a 5-second 176x144 3GP clip at 10 FPS produced an APNG several times the size of the source; dropping to 8-bit color with dither cut that back down sharply. Keep it small by lowering the framerate to 10 FPS, shrinking the resolution, or reducing the color palette in the "Colors" option before converting.

Will an APNG play in every browser?

Animated PNG has roughly 94.7% global browser support — Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, and Opera. In a viewer that does not support it (notably Internet Explorer and Opera Mini), the file gracefully falls back to showing the first frame as a static PNG, so nothing breaks; it just stops animating.

Should I convert 3GP to APNG or to GIF?

Pick APNG when you need lossless quality, more than 256 colors, or smooth alpha transparency — logos, screen recordings, and gradients look far cleaner. Pick GIF when universal compatibility matters more than fidelity, for example embedding in an email client or a very old platform. If you want a GIF instead, use our 3GP to GIF converter.

How long can the 3GP clip be?

APNG stores every frame, so duration times framerate equals total frames, and frames drive the file size. Short 3GP clips (the format's typical use) work best. For a longer clip, drop the framerate and resolution first, or keep it as a video — convert it with our 3GP to MP4 converter instead.

Does the APNG keep transparency from the source?

3GP video has no alpha channel, so a converted clip is fully opaque. APNG's 8-bit alpha support matters most when your source already has transparency (for example a screen recording with a transparent background). The format will preserve it; a plain 3GP simply has none to carry over.

Can I make the finished APNG smaller?

Yes. The biggest levers are framerate (10 FPS), resolution, and the "Colors" reduction-with-dither setting. After converting, you can shrink it further with our APNG compressor, which re-optimizes the file with lossless Zopfli-style compression.
