GIF Reverser

Play an animated GIF backwards, or forward and back as a boomerang.

Choose a GIF and pick Reverse or Boomerang. Every frame keeps its own delay, so uneven timing stays right, and the loop setting is kept. The preview plays the result before you download it.

No GIF selected.

You can also drop a file here.

Output
Choose a GIF to play backwards.

What GIF Reverser does

GIF Reverser plays an animated GIF backwards. Reverse turns the frame order around, and Boomerang plays the frames forward and then back again, so the animation swings to and fro without a jump at the loop.

Each frame keeps its own delay, so a GIF with uneven timing, such as a long pause on the first frame, still pauses on that frame. The loop setting stays as it was.

How to use it

  1. Select Choose GIF and pick a .gif, or drop one on the file row.
  2. Pick Reverse or Boomerang under Mode. The preview plays the result.
  3. Check the frame count and length under the preview, then select Download GIF.

Formats and limits

  • Input: one GIF file.
  • Output: a GIF named after the original with -reversed or -boomerang added, such as cat-reversed.gif.
  • Boomerang does not repeat the last or the first frame, so a GIF with 10 frames becomes 18. A GIF with one or two frames stays the same.
  • The frames are not changed, but the GIF is encoded again with its own palettes, so the file size can differ from the original. A Boomerang GIF is about twice as large.

Settings explained

Mode
Reverse plays the frames from last to first. Boomerang plays them first to last and then back toward the start.

Privacy

The frames are reordered in this tab, and the GIF is encoded in a Web Worker, a background thread of the same page. Nothing is uploaded, and the file is only written when you select Download GIF.

FAQ

Why does the first frame of my reversed GIF stay so long?

Delays move with their frames. If the original paused on its last frame, the reversed GIF pauses on its first. GIF Frame Editor or GIF Speed Changer can change the delays.

Why is the Boomerang file bigger?

It holds almost twice as many frames. GIF Optimizer can make it smaller.

Does it keep transparency?

Yes. Transparent pixels stay transparent in every frame.
