Rotate video files
Upload a video file and rotate it. For MP4 and MOV files the rotation is written as metadata, so it is lossless and near-instant; WebM and MKV files are re-encoded.

For MP4 and MOV files, rotation is written as container metadata: the video data itself is copied untouched, the operation is lossless, and it finishes instantly. Players then display the file correctly rotated.
For formats without rotation metadata, the tool re-encodes the frames at high quality instead, so the result is correct everywhere regardless.
Phone clips recorded before the sensor caught up with how you were holding it, footage from mounted cameras installed sideways, and screen recordings of rotated devices.
On MP4 and MOV, yes: only an orientation flag changes while streams are copied. Other containers get a high-quality re-encode.
A few old players ignore rotation metadata. If you hit one, rotating a re-encoding format like WebM bakes the rotation into the pixels themselves.
No, rotation happens locally either way.
