How to use this tool

- Pick how many bounces and the output format; the tool plays it forward, then backward, seamlessly joined.
- Press “Make a boomerang” and download the results, individually or as one ZIP.
About this tool
Forwards then backwards on a loop, with no visible join. Free and unlimited, and nothing is uploaded: it all runs in your own browser. Everything is analysed and produced on your own device — nothing is uploaded anywhere, and you can verify it: the tools keep working even offline.
Privacy & limitations
Files over roughly 2 GB, or long 4K videos, can exhaust the browser's memory — everything runs on your machine, so your machine is the limit. The bounce re-encodes the clip twice (forward and reversed); a long source makes a very long output — trim first.

Frequently asked questions
Why is there no visible join?
Because the clip is joined to its own reverse. The last frame going forwards is the first frame coming back, so there is no cut between them to see.
Why is the sound removed?
Audio played forwards and then immediately backwards is unpleasant, and a boomerang is a visual thing. Use Reverse if you want the sound reversed too.
How long should the source be?
One to three seconds. A boomerang plays through at least twice, so anything longer stops reading as a loop and starts reading as a video that went wrong.
