Why phone videos arrive sideways in the first place

Your phone does not rotate the pixels when you turn it. The sensor records the frame in its native orientation and writes a rotation flag into the file's metadata, a note that says display this 90 degrees clockwise. Players that read the flag show the video upright, and everything looks fine, right up until the file reaches something that ignores it.

That is the whole reason a clip can look correct in your gallery and land sideways in an editor, a browser, or somebody else's feed. Nothing is corrupted. Two pieces of software simply disagreed about whether to trust a note attached to the video, and the pixels underneath were always in the orientation the sensor used.

Rotating properly means baking the orientation into the pixels themselves and clearing the flag, so no downstream player has to be trusted to do the right thing. That is what this tool does, which is why the result stays upright everywhere rather than only in the players that happened to agree with you.

Rotate and flip video without uploading it anywhere

Rotation in 90 degree steps, plus horizontal and vertical mirroring for footage shot on a front camera or a mirrored webcam. The preview shows the real orientation of the output, not the flag, so what you see is what other people will see.

The work happens on your own machine. There is no upload, no watermark on the result, and no limit on the length or size of what you feed in, which matters because the videos most likely to be sideways are the long unedited ones straight off a phone.

If the clip also needs to end up in a vertical format rather than simply the right way up, the horizontal-to-vertical converter handles the reframing, and the cropper will tighten the shot once the orientation is settled.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

Can I fix a sideways phone video?

Yes. Rotate 90 or 270 degrees to turn a sideways clip upright.

Does my video get uploaded?

No. Rotating happens in your browser; your file never leaves your device.

Is there a watermark?

No. You get the same video with the orientation baked into the pixels, plus nothing: no watermark, no signup, no size limit.
