How to use

Load an MP4, WebM or MOV video that was filmed sideways.
Pick a rotation of 90 degrees clockwise, 180 degrees or 270 degrees.

Example

A clip recorded on a phone held upright appears lying down on a computer screen. A 90-degree turn in the right direction puts the picture back upright while keeping the soundtrack.

Limits and formats

The available turns are limited to 90, 180 and 270 degrees, with an optional mirror.
The wrong rotation can flip the image; check the preview before exporting.
The output file can depend on your browser and the original video.
The tool does not automatically crop black edges that may appear.
The file must match the formats and maximum size shown.

Where processing happens

The rotation is calculated in the visitor's browser. No copy of the video is sent outside, and the processing finishes without remote storage.

Frequently asked questions

How do I know whether to rotate 90 or 270 degrees?

Look at the direction in which the image is tilted. Try a 90-degree turn; if the result is upside down, use 270 degrees or add a 180-degree turn.

Do I have to use the mirror option?

No, the mirror is optional. Leave it set to none if you only want to straighten the picture without flipping left and right or top and bottom.

Does the rotated video keep its original framing?

Rotation changes the image orientation and may leave empty edges depending on the format. Check the result to decide whether you need extra cropping.
