Video Reverser
Video Reverser is a free online video effect tool. Upload a video, drag the timeline to pick a clip, and both the picture and sound are reversed into a backwards-playing MP4 — perfect for comedy, magic reveals, time-rewind effects, and other creative edits.
Everything runs locally in your browser with FFmpeg.wasm, so your videos are never uploaded to any server. Because reversing must buffer every frame of the clip in memory, clips are limited to 30 seconds, and longer clips are automatically scaled down to keep processing reliable.
How to Use
- Upload a video file, up to 300 MB
- Drag the timeline handles to pick the clip to reverse, up to 30 seconds
- Preview the selection to confirm the range
- Start the generation — reversing happens locally in your browser
- Preview the reversed video and download the MP4
FAQ
Are my videos uploaded to a server?
No. Reading, reversing, and result generation all happen locally in your browser via FFmpeg.wasm — nothing is sent over the network.
Why is a clip limited to 30 seconds?
Reversing must buffer every decoded frame of the clip in memory before writing them out backwards. Longer clips use far more memory, so clips are capped at 30 seconds to keep the tool reliable on most devices.
Why was my output resolution reduced?
Longer clips need a large frame buffer, so the tool automatically lowers the output resolution based on the clip length (with a notice on the page). Shorten the clip to keep a higher resolution.
Does the reversed video have sound?
Yes. The audio track is reversed along with the picture, producing the classic "rewind" effect. If the source video has no audio, the output has none either.
What format is the output?
Always MP4 (H.264 video + AAC audio), which plays on virtually any phone, computer, or platform.
