Online Lottie JSON to APNG (Animated PNG) converter

Convert your vector Lottie JSON animations (.json, .lottie, .tgs) into crisp, high-quality APNG (Animated PNG) files with full alpha transparency support. Our free online converter renders your Lottie vector graphics frame-by-frame into lossless or compressed animated PNG images.

Why convert Lottie to APNG instead of GIF?

Unlike traditional GIF files, which are limited to 256 colors and binary (on/off) transparency, APNG supports full 24-bit color depth and 8-bit smooth alpha channel transparency. If your Lottie animation features smooth semi-transparent shadows, gradients, or soft vector edges, converting it to APNG ensures the background blends seamlessly onto any light or dark web page without unwanted color artifacts or pixelated edges.

Key Features

  • Full Alpha Transparency: Preserves smooth semi-transparent gradients and soft shadows from vector graphics.
  • Customizable Size & Speed: Adjust target width, height, and frame rate (FPS) before converting.
  • No Quality Loss: Renders sharp vector lines into 24-bit PNG frames.
  • 100% Free & Automatic Cleanup: Uploaded files are private and automatically deleted after 1 hour.
