No. Everything runs in your browser - your file never leaves your device. How this is verifiable
A "reverse effect" for social media, a small trick clip (someone "spits" a drink back into the glass) or simply curiosity about how a motion looks backwards - this tool plays a video completely from end to start, frame by frame in reverse order.
Important and honest: because reversal needs random access to every frame, the video is fully decoded and held in the browser tab's memory first - so at most about 30 seconds of source material is supported (possibly less at high resolutions). The audio track is deliberately NOT reversed: a naive backwards playback of audio chunks would just sound chopped and wrong, not a real sample-accurate reversal like the sibling "Reverse audio" tool - an honestly silent result beats a wrong soundtrack.
Everything runs locally in the browser with mediabunny (MPL-2.0, self-hosted, no third-party CDN) on the browser's native WebCodecs API. Your video is not uploaded.

Limitations: Audio is not reversed along with the video (deliberately silent instead of wrong-sounding). Because fully decoding the clip needs real memory, only about 30 seconds of source material is supported - longer or very high-resolution videos are honestly truncated to the opening section, shown in the output filename. One file per run, ~600 MB limit. Needs a secure context (https) and browser WebCodecs support.
No. The whole reversal happens locally in your browser.
No, deliberately not. A real, sample-accurate audio reversal is a very different job from reversing frame order - a roughly chopped-up soundtrack would be worse than none.
About 30 seconds, possibly a bit less at high resolutions - the video must be fully decoded before it can be reassembled in reverse.
Then only the opening section up to the limit is honestly reversed, visible in the filename suffix - no silent data loss without a hint.
No, only the frame order - width and height stay unchanged.
