How to Rotate a Video (and Fix Sideways Clips)

To rotate a video, open a rotate tool, drop in your clip, choose 90 degrees right, 90 degrees left, or 180 degrees, then download the result. That re-saves the file with the correct orientation locked into the frames, so it plays the right way up everywhere, not just on your phone.

Why your video looks fine on your phone but sideways everywhere else

This is the single most common video complaint, and it is not your imagination. When a phone records, it often captures the frames in one orientation and stores a separate rotation flag in the file's metadata telling the player how to turn the picture before showing it. Your phone's gallery app reads that flag and displays the clip correctly. The problem is that plenty of other apps and players ignore the flag entirely, so the same file that looks perfect on your phone shows up sideways or upside-down once you upload it, email it, or open it on a desktop.

Because the flag is not honored consistently, you cannot rely on it. The reliable fix is to rotate the video and re-save it so the correct orientation is physically baked into the frames themselves. Once the pixels are turned the right way, there is no flag to interpret and no player left to guess wrong. That is exactly what the rotate video tool does: it turns the actual image and writes out a file that displays correctly in every player.

How to rotate a video, step by step

• Open the rotate tool and drop your video onto it. Your file is never uploaded to a server, there is no account to create, and nothing gets watermarked.
• Pick your rotation. Choose 90 degrees right (clockwise) or 90 degrees left (counter-clockwise) for a clip that is lying on its side, or 180 degrees for one that is fully upside-down.
• Check the preview so you can confirm the picture is now the right way up before you commit.
• Keep the quality setting on High. Rotating re-encodes the video (more on why below), so a higher setting protects the image.
• Download the corrected file. The new orientation is now part of the frames and will look right anywhere you open it.

Which direction do you need?

• Sideways, top of the scene points right: rotate 90 degrees left (counter-clockwise).
• Sideways, top of the scene points left: rotate 90 degrees right (clockwise).
• Completely upside-down: rotate 180 degrees.
• Not sure: try one 90-degree option, glance at the preview, and switch to the other if it went the wrong way. There are only a handful of possibilities, so you will land on the right one quickly.

Rotating 90 degrees swaps width and height

When you rotate a clip by 90 or 270 degrees, its dimensions flip: a landscape 1920x1080 video becomes a vertical 1080x1920 video, and the reverse for a vertical clip turned on its side. This is expected behavior, not a crop, and none of your footage is cut off. If a landscape recording that was stored sideways suddenly reads as a tall vertical video after rotating, that is the correct result. A 180-degree rotation keeps the same dimensions because it simply flips the image end over end.

Why rotating changes the file (and trimming doesn't)

Trimming a video can often just cut at existing points and copy the rest untouched, which is why it is fast and lossless. Rotating is different: every frame has to be redrawn in its new orientation, which means the video is re-encoded from scratch. Re-encoding always carries some risk of quality loss, so keep the quality on High to keep the result as close to the original as possible. This is also why rotation takes a little longer than a simple trim, especially on longer clips.

What you can and cannot do

Rotation works in fixed 90-degree steps: 90, 180, and 270 degrees (270 being the same as 90 the other way). You cannot rotate by an arbitrary angle like 12 or 45 degrees, because that would require cropping into the frame or padding the edges with empty space to keep a rectangular picture. Fixed rotations avoid both problems and keep every pixel of your footage intact, which is precisely what you want when the goal is to fix an orientation, not to add a creative tilt.

Fix it once and be done

A sideways clip is almost always a metadata mismatch rather than a damaged file, so the fix is quick and permanent. Drop your video into the rotate video tool, choose 90 degrees left, 90 degrees right, or 180 degrees, keep quality on High, and download. The corrected orientation is baked into the frames, your file stays private and free of watermarks, and the clip will finally play right way up wherever you share it.
