How to use

There are 2 options:

  • Run using Docker. One-line command, the option requires only Docker installed
  • Download and run compiled executable files. The option requires run-time dependecies installed

Using Docker

Replace with directory with Lottie animations / Telegram stickers and run:

  • Convert to GIF:
    docker run --rm -v <path to directory>:/source edasriyan/lottie-to-gif
    
  • Convert to PNG:
    docker run --rm -v <path to directory>:/source edasriyan/lottie-to-png
    
  • Convert to APNG:
    docker run --rm -v <path to directory>:/source edasriyan/lottie-to-apng
    
  • Convert to WEBP:
    docker run --rm -v <path to directory>:/source edasriyan/lottie-to-webp
    
  • Convert to WEBM:
    docker run --rm -v <path to directory>:/source edasriyan/lottie-to-webm
    

You can provide parameters via env variables:

  • HEIGHT: Output image height. Default: 512
  • WIDTH: Output image width. Default: 512
  • FPS: Output frame rate. Default: apng,png,webp - 60; gif - 50
  • QUALITY: Output quality. Default: 90
  • THREADS: Number of threads to use. Default: number of CPUs

Example:

docker run --rm -e HEIGHT=256 -e WIDTH=256 -e FPS=30 -v /home/ed/Downloads/lottie-animations:/source edasriyan/lottie-to-apng

Results will be saved next to each source file in the same directory.

Using compiled executables

  1. Install run-time dependencies. Make sure the path to them present in PATH variable:
    • gifski if you want to convert to GIF
    • ffmpeg if you want to convert to APNG or WEBM
    • img2webp if you want to convert to WEBP
  2. Download executable from releases section of this repo for your OS and arch
  3. In downloaded archive find the following executable scripts:
    • lottie_to_apng.sh
    • lottie_to_gif.sh
    • lottie_to_png.sh
    • lottie_to_webp.sh
    • lottie_to_webm.sh
    All of them have the same CLI:
    $ ./bin/lottie_to_gif.sh -h                       
    usage: ./bin/lottie_to_gif.sh [--help] [--output OUTPUT] [--height HEIGHT] [--width WIDTH] [--threads THREADS] [--fps FPS] [--quality QUALITY] path
