How to rotate videos online
Whether you recorded a video in portrait mode by mistake, need to rotate footage from your phone, or want to flip a video upside down, this free video rotator makes it easy. Simply select your rotation angle and click a button — the video is processed directly in your browser.
Unlike server-based tools, this rotator processes everything in your browser using FFmpeg WebAssembly. Your video files are never uploaded to any server, ensuring complete privacy. The tool supports MP4, WebM, MOV, and AVI formats, and preserves the original format in the output.
The first rotation requires a one-time download of the video engine (~30 MB), after which subsequent rotations start immediately. The video is re-encoded at high quality settings (CRF 23 for MP4/MOV, CRF 30 for WebM) to minimize quality loss while reducing file size.
Frequently asked questions
How do I rotate a video?
Upload your video, select a rotation angle (90°, 180°, or 270°), then click Rotate Video. Download the result when processing is complete.
Is my video uploaded to a server?

What video formats are supported?
The rotator supports MP4, WebM, MOV, and AVI formats. The output is saved in the same format as the original.
Will rotating reduce video quality?
