Page guide

Play an animated GIF backwards. Each frame keeps its original display time.

How to use Reverse GIF
  1. Choose a GIF and select Reverse GIF. The last frame becomes the first. Preview the animation and download the new file.
  2. Every frame keeps its original delay when the order changes. The original loop count is preserved. Transparency and frame disposal are decoded before the frames are reversed.
