About this tool
Play a clip backwards, sound and all. 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. Reversing requires reading the whole file into the engine's memory — long videos are the practical ceiling here more than anywhere else.

Frequently asked questions
Why is there a length limit?
Reversing cannot begin until the end has been read: the last frame has to come out first, so the whole clip is held in memory at once. That is inherent to the operation rather than a limitation here, and the cap exists so a long video fails with an explanation rather than by exhausting the tab.
Does the audio reverse too?
Yes, when there is any. Speech played backwards is famously strange; music and ambient sound often survive it rather well.
Can I reverse just part of a clip?
Trim it to the part you want first, then reverse that.
