What is Video Rotator?
A video rotator fixes clips that were recorded in the wrong orientation - sideways phone videos being the classic case. This tool re-encodes the video with FFmpeg in your browser, physically rotating every frame 90° clockwise or counterclockwise, turning it 180°, or mirroring it horizontally or vertically. Because the rotation is baked into the pixels rather than stored as a metadata flag, the fixed video displays correctly in every player.

Frequently asked questions
Why does my video play sideways in the first place?+
Phones record sensor-orientation video and store a rotation flag telling players how to display it. Some players and platforms ignore that flag. This tool physically rotates the frames so the flag no longer matters.
Does rotating reduce quality?+
Rotation requires re-encoding, which costs a small amount of quality - visually negligible at the settings used. The resolution itself is preserved exactly (width and height swap for 90° rotations).
Can I rotate and flip at the same time?+
Apply one transform, download the result, and run it through again for combinations. Most orientation fixes need only a single step.
Is the video uploaded for rotation?+
No. FFmpeg runs in your browser via WebAssembly and every frame is transformed on your own device.
Does the audio change?+
No. The audio track is copied through untouched - only the picture is rotated or flipped.
