Reverse a video online

Reverse Video lets you play any video backwards online, from the last frame to the first, and reverses its audio along with it — all 100% in your browser. Drop in an MP4, WebM or MOV clip, click Reverse, and download a new reversed MP4 in seconds. This free video reverser is powered by ffmpeg.wasm, so your file is processed locally on your own device and is never uploaded to any server. Whether you want to rewind a clip for a fun backwards effect, create a reverse-motion loop, or flip a short video for social media, everything happens privately in your browser.

🔒 100% private — files never leave your device

How to use

  1. Drop in a video file (MP4, WebM, MOV and more) or click to select one from your device.
  2. Click Reverse — the ffmpeg.wasm engine downloads on first use, then rewinds the video and its audio.
  3. Wait while the whole clip is processed locally; the progress percentage updates as it runs.
  4. Download the reversed MP4 once processing finishes — nothing was ever uploaded.

Frequently asked questions

What video formats can I reverse?

You can reverse common video formats including MP4, WebM and MOV. The reversed clip is always exported as an MP4 so it plays reliably everywhere.

Is my video uploaded anywhere?

No. Everything runs locally in your browser with ffmpeg.wasm — your video is never uploaded to any server, so your files stay completely private.

Does it reverse the audio too?

Yes. It reverses both the video and its audio together. If the clip has no sound, the tool automatically falls back to reversing the video alone.

Why is it slow on long videos?

Reversing needs the entire clip held in memory before it can be played back from the end, so very long or high-resolution videos take longer and use more memory.

Does it need to download anything?

The first time you reverse a video, the ~30 MB conversion engine (ffmpeg.wasm) downloads. After that it is cached and runs offline, with no further downloads.

Will reversing reduce the quality of my video?

The tool re-encodes the reversed clip to MP4, so there may be minor compression, but it keeps the original resolution and aims to preserve visual quality.
