Reversing holds every frame in memory. On a phone, reverse about 10 seconds of 1080p video at a time; the full 30 seconds may need a computer.

Upload a short video and play it in reverse, right in your browser. No upload to a server, no watermark.

MP4, WebM, or MOV
Full reversal works on videos up to 30s and 50MB — this keeps the whole clip in memory while it plays backwards. For longer videos, use range mode below to reverse just a clip.
Upload a video to play it backwards
This free tool plays your video backwards using ffmpeg running entirely inside your browser. Upload a clip, choose whether to keep the (reversed) audio, and download the result in seconds — nothing is ever sent to a server.
Is my video uploaded to a server?
No. Everything happens locally in your browser using ffmpeg.wasm — your video is never uploaded anywhere.
What video formats are supported?
You can upload MP4, WebM, or MOV files. The reversed result is always saved as an MP4.
Will the reversed video have sound?
Yes, by default the audio is reversed along with the picture. You can mute the reversed audio instead if you prefer a silent clip.
Why is there a 30-second limit?
Reversing a video requires decoding and holding every frame of the processed span in memory before it can play backwards, so a long clip can exhaust your browser's available memory. Capping full reversals at 30 seconds and 50MB keeps this reliable; use range mode to reverse a short clip out of a longer video instead.
Can I reverse just part of a longer video?
Yes — enable 'Reverse only a selected range' and pick a start and end time up to 30 seconds apart. Only that portion is decoded and reversed, so the source video itself can be longer.
Why does reversed audio sound strange?
Audio waveforms aren't symmetrical, so playing them backwards changes their pitch and rhythm in ways that don't match normal speech or music patterns — that's why reversed voices often sound garbled or otherworldly. Mute the reversed audio if you'd rather keep the video silent.
Your video is processed entirely on your device. It is never uploaded to our servers, keeping your content completely private.
