How to reverse a video
- Press Choose video and pick a clip, or drop it on the box. MP4 and MOV files from phones and cameras work best.
- Choose what happens to the sound: reversed with the picture, kept playing forwards, or removed.
- Press Reverse video. The last frame becomes the first, and the clip plays backwards to the start.
- Watch the preview, then press Download MP4.
Limits
To play a video backwards, every frame has to be decoded and encoded again, and that happens on your device. To keep memory in check, the tool works through the video in short pieces, from the end to the start, and holds at most about 96 MB of decoded frames at a time. The browser needs a lot more than that for decoding, encoding and the picture itself: in our tests on a laptop, reversing 10 seconds of 1080p video peaked at about 0.8 GB in Chrome’s page and graphics processes when saving at 1080p, and about 1.3 GB when scaling down to 720p.
| Item | Fast path | Fallback |
|---|---|---|
| Used for | MP4 and MOV in browsers with WebCodecs | WebM, MKV, and browsers without WebCodecs |
| Longest video | 3 minutes (1 minute on phones and tablets) | 60 seconds |
| Output size | Up to 1080p (720p by default) | Up to 720p |
| Speed in our tests | 60 s of 1080p: about 25 s in Chrome, 2.5 to 3 min in Firefox and Safari’s engine | 10 s of 1080p: about 18 s |
Speeds are from our own tests on a laptop, saving at 720p; yours will depend on your device. The output is always an H.264 MP4 with AAC sound. Frame rates above 60 fps are saved at 60 fps, on both paths. In Firefox, the sound goes through the fallback encoder, which downloads about 32 MB once.
Phones and tablets get a 1-minute limit and start at 720p, because a phone browser can close the tab when memory runs short. The page treats your device as a phone or tablet when the browser says it is mobile (Chrome’s client hints, or the browser’s user-agent string, which names Android, iPhone or iPad), and also applies the limit in Chrome on devices that report 4 GB of memory or less.
FAQ
How can I reverse a video so it plays backwards?
Choose the video above and press Reverse video. The tool decodes the clip, writes the frames out in the opposite order with the same timing, and saves a new MP4. If you keep the sound on Reverse, the audio is flipped too, so it lines up with the picture.
Where can I reverse a video for free?
Right here. There’s no sign-up, no watermark and no daily limit, because the work happens in your own browser rather than on a paid server. The trade-off is the length limit: 3 minutes on the fast path, 60 seconds on the fallback, and 1 minute on phones and tablets.
Can I reverse a video but keep the sound normal?
Yes. Pick “Keep the original sound” before you press Reverse. The picture plays backwards and the original audio plays forwards over it. Pick “No sound” to save a silent clip.
How do I reverse a video on my phone?
Open this page in your phone’s browser, tap Choose video and pick a clip from your gallery. Phones have less memory than computers, so on a phone the limit is 1 minute and the resolution starts at 720p. We have tested with phone emulation in Safari’s and Chrome’s engines on a computer, not on a physical phone yet.
Does this tool upload my video?
No. Your video is read and processed by your browser on your own device, and the MP4 is created there too. You can check: open your browser’s developer tools, go to the Network tab, and reverse a video. No request carries it. The page counts visits and finished downloads (tool name only) with analytics that sets no cookies, and no file data is ever sent (see privacy).
Why is there a length limit?
Video files are stored so they can be played forwards: most frames only record what changed since the frame before. To get a frame near the end, the frames before it must be decoded first. The tool decodes one short section at a time, from the last section to the first, which keeps memory bounded but means the whole video is decoded and re-encoded on your device. Long videos would take too long and could run a phone out of memory.
Is this a reverse video search?
No. This tool plays a video backwards. A reverse video search is something else: it looks for where a video or image appears online. This page doesn’t search for anything, and your video never leaves your device.
