Rotate Video
Rotate video online for free — fix sideways and upside-down phone videos by rotating them 90° clockwise, 90° counter-clockwise or 180°, and mirror them if needed. The pixels are rotated (not just a flag), so it plays correctly everywhere. Runs privately in your browser.
100% private — your video is processed on your device, never uploaded. Conversion happens on your device; nothing is uploaded.
Processing uses your browser’s built-in video encoders (WebCodecs) through the open-source Mediabunny library — your video is never uploaded. Works best in recent Chrome, Edge and Safari; the output is kept in memory, so very large files (several GB) may need a computer with plenty of RAM.

How do I rotate a video 90 degrees?
Drop the video in, choose 90° clockwise (or counter-clockwise), and click Rotate video.
Why does my rotated video play correctly everywhere?
Some tools only add a rotation flag that certain players ignore. This tool rotates the actual frames, so every player shows it the right way up.
Does rotating reduce quality?
The video is re-encoded at a high bitrate, so the difference is hard to see.
Is my video uploaded?
No. The video is read and encoded by your own browser using its built-in video encoders, so it never leaves your device — even large or private videos stay private.
Is there a file size limit?
There's no upload limit. The finished video is held in memory before download, so files up to a few GB work on most computers; very large files need more RAM.
Which browsers work?
Recent Chrome, Edge and Safari work best (they have hardware video encoders). Firefox 130+ works for most files.
