Rotate video

Questions fréquemment posées

Why is rotating so fast?

MP4 and MOV files store a display rotation. Toolula changes that value and copies the video data unchanged, which takes seconds and keeps the original quality.

An app still shows my video sideways — what now?

Some older players and editors ignore the rotation value. Tick “Re-encode the turn into the picture” and the frames themselves are rotated.

Is my video uploaded to a server?

No. The file is read and written inside your browser tab using WebCodecs — nothing is uploaded, there is no account and no watermark. Once loaded, the page also works offline.
