Is Reverse video free? Is there a watermark?

Yes — Reverse video is free to use with no sign-up or watermark. Very large files can still be limited by your browser's available memory and processing resources.

Do my files get uploaded to a server?

No. Reverse video runs entirely in your browser with WebAssembly, so your MP4, MOV, WebM, MKV file never leaves your device and nothing is stored or seen by us.

What can I put in, and what do I get out?

Reverse video accepts MP4, MOV, WebM, MKV and gives you back a MP4 file. Actual codec support depends on what the bundled engine or browser decoder can read.

Does Reverse video change my original file?

No. It never touches your original — Reverse video creates a brand-new MP4 file to download and leaves the source on your device untouched.

Get a better result

Best for: Short visual reveals, backward-motion effects, and shots whose action remains understandable when played in reverse without sound.
Input → output: The complete video stream is reversed and encoded as H.264/yuv420p MP4. Audio is deliberately removed instead of reversed or preserved.
Quality tip: Trim to the exact action first. A shorter input uses less browser memory and makes the reversed movement easier to judge.
Know before running: The reverse filter buffers frames and becomes expensive on long or high-resolution clips. Output is silent and receives another lossy H.264 encode.
Next step: Boomerang loop to combine forward and backward motion in one repeating gesture.
