About Rotate Video — Free Online Tool

Rotate Video turns a clip 90, 180 or 270 degrees, or mirrors it, and writes the new orientation into the picture itself.

The pixels are genuinely moved by ffmpeg's transpose filter, and the container rotation flag is then written as zero so no player adds a second rotation of its own — a sideways phone video fixed here stays fixed in the players that read the flag and in the ones that ignore it. Because the frame really turns, a quarter turn swaps the dimensions: 1920x1080 comes back as 1080x1920. Horizontal and vertical mirroring can be applied as well as a rotation or instead of one, and asking for neither is refused rather than handing back an identical file. Any angle you type is snapped to the nearest quarter turn.

The rotation runs locally. A video is not worth handing to a server merely to turn it the right way up.

Fixing a clip a phone recorded sideways, uprighting footage from a camera mounted upside down, mirroring a selfie recording so text in shot reads correctly, and correcting orientation before an upload that offers no rotate button afterwards.

When to use it

Fix videos recorded horizontally where the phone sensor failed to trigger auto-rotation.

How it works

Applies transpose=1 (90 CW) or transpose=2 (90 CCW) video filters during encoding.

Metadata vs Transcode Rotation

Rotating the pixels rather than setting a metadata flag means players that ignore the flag still show the video upright.
