About reversing a video in the browser
This plays a video — picture and sound both — backwards from end to start, a well-worn short-form effect. Unlike the other video tools here, which process one frame at a time as the video streams through, a true reversal needs every frame decoded and held in memory before any of them can be written back out in the opposite order, since there's no way to know the last frame until the whole video has been read.
That's also why it's capped at 30-second clips: memory use scales with how many frames get held at once, and an uncapped long video could exhaust a browser tab's available memory. The audio is decoded, reversed sample-by-sample, and muxed back in alongside the reversed video, so the result sounds right, not just looks right. Everything happens on your device; nothing is uploaded.

Reverse Video — frequently asked questions
Is my video uploaded?+
No. It's reversed entirely in your browser.
Does the audio reverse too?+
Yes — both video and audio play backwards, so it sounds right, not just looks right.
Why the 30-second limit?+
Reversing needs every frame held in memory at once before re-encoding — there's no way to stream it. 30 seconds keeps memory use reasonable in a browser tab; trim a longer clip first with Trim Video.
Which browsers work?+
Chrome, Edge and Safari 17+ — reversal needs WebCodecs.
Do you upload my files to a server?+
No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.
Is there a file size limit?+
There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
