Turn AVIF images into an animated APNG: drop several AVIF stills to build a frame-by-frame animation, or upload a single animated AVIF (AVIFS) and re-encode it as APNG for wider playback. APNG keeps AVIF's full 24-bit color and 8-bit alpha transparency intact and plays in roughly 94.7% of browsers, with a clean first-frame fallback everywhere else — useful when an animated AVIF won't render in an older viewer, editor, or email client.
How to Convert AVIF to APNG
- Upload Your AVIF Files: Drag and drop one animated AVIF, or add several still AVIF images in the order you want them to play. You can queue a batch at once.
- Set the Framerate: Open the options and pick a Framerate — 10 FPS (Recommended) suits most loops; raise it to 15-30 FPS for smoother motion or drop it to 2-5 FPS for a slideshow feel.
- Tune Colors and Image Quality (Optional): Leave the full palette for photographic gradients, or use Colors (with optional dither) to shrink the file; adjust Image quality (%) and resolution preset to balance size against detail.
- Convert and Download: Click Convert and save your animated PNG. No sign-up, no watermark.
APNG vs GIF for Your Animation
| Property | APNG | GIF |
|---|---|---|
| Color depth | 24-bit (16.7M colors) | 8-bit (256 colors) |
| Transparency | 8-bit alpha (smooth edges) | 1-bit (on/off only) |
| Browser support | ~94.7% (Chrome 59+, Firefox 3+, Safari 8+, Edge 79+, Opera 46+) | Effectively universal |
| Fallback when unsupported | First frame shown as a static PNG | N/A |
| Best for | Soft-edged stickers, gradients, logos with alpha | Maximum legacy reach, simple loops |
Frequently Asked Questions
Can I convert an animated AVIF to APNG?
Yes. AVIF can store animation (sometimes saved as AVIFS), and this tool re-encodes that animated AVIF into an APNG frame for frame. APNG is handy when a viewer, image editor, or email client can play animated PNG but not animated AVIF.
Will the conversion keep AVIF's transparency?
Yes. AVIF supports an alpha channel, and APNG carries full 8-bit alpha transparency, so soft, anti-aliased edges and partial opacity survive the conversion without the jagged 1-bit cutout you get from GIF.
How do I control the animation speed?
Use the Framerate option. It runs from 1 FPS (a slideshow) up to 50 FPS, with 10 FPS set as the default. A higher framerate plays the same frames faster and produces smoother motion; a lower one slows the loop and trims file size.
Why is my APNG larger than the AVIF?
AVIF uses AV1 video-grade compression, which is far more efficient than PNG. APNG is essentially lossless PNG per frame, so the same animation is usually bigger. To reduce size, lower the Colors count, enable dither, drop the resolution preset, or reduce Image quality (%). If you only need one still rather than the full loop, convert AVIF to PNG instead.
Do my files stay private?
Yes. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public. In our testing, a short three-frame AVIF set at 10 FPS and the full palette produced an APNG of about 180 KB.
