Rotate or flip a video
Turn a sideways or upside-down video the right way up, or mirror it. Done on this device, never uploaded.
- Nothing is uploaded

- No watermark · limit is your device’s memory; phones hold less
Rotates a video by 90° or 180° or flips it, from MP4, MOV or WebM to MP4. It is free, needs no account and adds no watermark, and your files are not uploaded: everything runs in your browser on your device. The size limit is your device’s memory, and phones hold less; give the page a short while after one visit to save itself for offline use, and then it works offline.
Done
Open the network tab. Your files never appear in it.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
How it works
- Drop one or more videos (MP4, MOV, WebM or MKV), or tap to pick them.
- Choose how far to turn them, and tick a flip if you want a mirror image.
- Rotate. Each video is re-encoded the right way up into an MP4 and downloads straight away.
In your browser, not on a server
Mediabunny (MPL-2.0) reads the MP4, MOV, WebM or MKV container in your tab. Each frame is decoded by your browser (WebCodecs), turned and flipped, and encoded again, H.264 where the browser has it and VP9 or AV1 otherwise, so the turn is part of the picture rather than a flag some players ignore. The sound is copied as it is when the MP4 can hold it.
Compared with upload-based tools: Online rotators upload the video to turn it on a server, cap the file size, and some add a watermark. A sideways phone video is often a personal one. Here it never leaves your device, and you can rotate a batch at once.
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Is my video uploaded?
No. Your browser decodes the video, turns each frame and encodes it again with its own video encoder, all in this tab. There is no upload and no watermark.
Will the rotation show everywhere?
Yes. Some tools only set a rotation flag that certain players ignore. Here the turn is built into the picture itself, so the video looks the same in every player, editor and upload form.
Which way is 90° right?
Clockwise. A video filmed with the phone turned left, that plays lying on its side, usually needs 90° right; if it ends up upside down, choose 90° left instead.
Does rotating lower the quality?
Turning the picture means encoding it again. That is done at high quality, so the result is close to the original, and the sound is copied as it is.
