How to Reverse a GIF in 3 Steps
Drop a GIF
Drag an animated GIF onto the left pane; it previews immediately.
Choose a mode
In Settings pick Reverse for a plain backwards loop or Boomerang, which plays forward then backward so the loop never jumps.
Reverse and download
Click Reverse GIF. Frames are re-ordered and re-encoded in a second; download from the toolbar.
GIF Reverser — Frequently Asked Questions
Is my GIF uploaded anywhere?
No. The GIF is decoded frame by frame in your browser and re-encoded on your device with a small open-source encoder. Nothing leaves your computer.
Does it keep the original frame timing?
Yes. Each frame's own delay is preserved, so GIFs with mixed timing (a long pause on the last frame, for example) play exactly as before.
Does Boomerang double the file size?
Almost — it contains every frame twice except the turning points, so expect roughly 1.9× the original size. Run the GIF Compressor afterwards if that matters.
Will the quality change?
Frames are re-quantised to a 256-colour palette built from the GIF itself, so the result is visually identical for almost all GIFs. Photographic GIFs with thousands of subtle shades may show slight banding; no dithering is applied to keep files small.
