GIF → animated PNG (APNG)

POST /api/gif-to-apng

Convert an animated GIF to an animated PNG (APNG). Preserves every frame and its delay. APNGs are backwards compatible — viewers that don't understand the animation chunks just show the first frame.

Re-encodes an animated GIF as an animated PNG (APNG). Every frame is composited (handling GIF's disposal modes), encoded losslessly, and packed into a standard APNG file. APNGs are a strict superset of PNG — a viewer that doesn't know about animation just sees the first frame, so the output works as a fallback PNG too. Compared to animated WebP, APNGs are larger but render correctly in older browsers and image viewers.
