Page guide

Make a GIF play forwards and then backwards for a back-and-forth animation.

How to use Ping-pong GIF
  1. Choose a GIF and run the tool. It keeps the original sequence, then adds the interior frames in reverse order. Preview the result before downloading.
  2. The first and last frames are not duplicated at the turning points. Every frame keeps its display time. The original loop count is preserved; a GIF that played once will still play once.
