Play a short clip backwards, sound and all. The page does the memory maths from your real file first, so a job that cannot fit never freezes your tab.

Play it backwards: the splash rises back into the glass, the falling dominoes stand up, the jump lands in reverse. Reverse Video takes a short part of a clip and writes it frame by frame in the opposite order, sound included, all inside your browser.
Short is the honest headline. The part you reverse has a hard length cap that depends on its size, and the cap is printed on this page with your file’s numbers, because reversing means holding every frame in memory at once and a browser tab only holds so much. A five minute video is not reversible here. Ten great seconds are.
1. Add the video. A preview and the file’s facts appear, including the exact second limit for its size.
2. Set the start and end of the part to reverse, in seconds or m:ss form. Keep it inside the limit shown.
3. Choose the sound: reversed with the picture, muted, or kept playing forwards.
4. If the part is too long, pick the 720p or 480p downscale and the limit grows. Press Reverse the Video and download.
Reversed sound is half the joke: speech turns to gibberish, impacts whoosh backwards, music swells the wrong way. Keep it when the clip is about the effect. Mute it when the reversed audio would fight a caption or a voiceover you plan to add. Keeping the sound forwards while the picture runs backwards is a known surreal trick, and it is offered because some clips genuinely want it, but know that the two fall out of step more as the part gets longer.
The engine note: this runs a real encoder inside your browser. Adding your first file downloads about 31 MB of engine files once, your browser caches them, and your video itself never leaves the device.
The caps come from one piece of arithmetic the page does for you: seconds times frames per second times width times height times 1.5 bytes per pixel. At 1080p and 30 frames a second that memory budget gives about 15 seconds of headroom, at 720p about 30, at 480p about 60, and 60 fps footage halves each figure. Exceed the cap and the tool refuses with the numbers shown, rather than eating your tab’s memory until the browser gives up. Files up to 500 MB load, but the cap is about the frames, not the file. For longer reversed passages a desktop editor, which streams frames from disk, is the right tool, and the usual video tools here handle the everyday jobs.
Every frame of the part must sit in memory simultaneously while the reversed file is written. A tab has a memory ceiling, and at HD sizes a minute of frames is several gigabytes. The cap keeps the job inside what a browser can safely hold.
Downscale it. The 480p option quadruples the seconds you can reverse compared with 1080p, and for a social clip the smaller frame is usually fine.
Only if you choose it. The default reverses sound and picture together. You can also mute the sound or keep it playing forwards.
Yes. The output is an ordinary MP4 written in reverse order, not a trick file, so any player shows it.
Not on this page. Convert the GIF to MP4 first, reverse the part you need, and convert back if a GIF is what you want to share.
The part is re-encoded once at a high quality setting, so a small cost. Downscaling, when you choose it, is the bigger and deliberate trade.
