A sideways video is annoying to watch and just as annoying to fix. You filmed it on a phone, it looks fine there, and then it lands on a computer lying on its side. To rotate video is to turn the picture itself, so it plays the right way up everywhere.
This tool turns a video a quarter at a time and can also mirror it. It opens at 90° clockwise, and the stage shows your video with that turn already applied. The Result line tells you the new size. It all runs in your browser, so your file is not uploaded.
Below is how the controls work, what order the turn and the mirror happen in, and how to fix the most common problems.
How to rotate a video, step by step
- Drop your video onto the page, or choose it from your device.
- The tool opens at 90° clockwise, so the stage already shows your video turned a quarter to the right.
- Under Turn, press Turn left or Turn right until the picture stands upright. Each press turns it a quarter of the way round. The words next to the label show where you are: No turn, 90° clockwise, Upside down or 90° anticlockwise.
- If you also want a mirror, switch on Mirror left to right, Flip upside down, or both. Then check the Result line for the size the finished video will have.
- Press Rotate. Save each result, or download them all as a zip.
The stage turns and mirrors as you change the settings, so you can see the result before you commit. If you go back to No turn with both mirrors off, the Rotate button is blocked with the hint "Turn or mirror it first", so you cannot save an unchanged copy by accident.
Rotate video 90 degrees, 180 degrees or the other way
The Turn control has two big buttons, Turn left and Turn right, with a letter F between them. The F shows what your settings do to an upright picture. Your own video on the stage gets the same turn, so judge by the stage: when your picture stands upright, the turn is right.
| Label | What happens | From the start, press | Size changes? |
|---|---|---|---|
| No turn | The picture stays as it is | Turn left once | No |
| 90° clockwise | A quarter turn to the right | Nothing, the tool opens here | Width and height swap |
| Upside down | A half turn, so the picture is turned right round | Turn right once | No |
| 90° anticlockwise | A quarter turn to the left | Turn right twice, or Turn left twice | Width and height swap |
A quarter turn changes the shape of the frame. A wide 1920×1080 video becomes a tall 1080×1920 one. That is why the Result line matters: it shows the swapped size so you are not surprised. A half turn leaves the size alone.
Fix a sideways phone video
Work out which way the top of the picture points. If it points left, the 90° clockwise the tool opens with already fixes it: check the stage and press Rotate. If it points right, press Turn right twice, or Turn left twice, until the label reads 90° anticlockwise.
This tool re-draws the picture itself, so what you see on the stage is what is in the saved file. It will not depend on how a player reads the video.
Rotate an iPhone video on your computer
To rotate an iPhone video here, first copy the clip to a Windows, Mac or Linux computer. Then open this page in Chrome, Edge or Firefox and drop the clip in. iPhone clips are usually HEVC (H.265) in a MOV file.
A clip filmed with the phone held upright is often stored on its side, with a note that tells players to show it upright (rotation metadata). The tool reads that note, so the stage shows the clip the way your phone did, and the turn you choose is added once, on top. If your browser cannot decode HEVC, the job is slower and the file can be up to 2 GB.
Fix an upside-down video
If the whole picture is upside down, press Turn right once from the start, so the label reads Upside down. That is a half turn, so the size stays the same and the picture is the right way up again, with writing reading correctly.
Flip video: mirror left to right or top to bottom
Turning and mirroring are not the same thing. Turning spins the picture. Mirroring flips it as if you were looking at it in a mirror. The tool gives you two switches for it.
- Mirror left to right: the left side becomes the right side. Writing in the picture will read backwards.
- Flip upside down: the top becomes the bottom.
Turning a picture upside down is not the same as flipping it top to bottom. A half turn also swaps left and right. A top-to-bottom flip does not. If you only want the vertical flip, see flip video upside down. For a plain left-to-right mirror, there is a dedicated page for mirror video.
A mirror is useful when a selfie camera has saved the picture the wrong way round, or when you want to match the direction of movement between two clips. It is a poor idea for anything with text, signs or logos, because they will read backwards.
If you switch on both mirrors at once, the result is the same as a half turn. The tool treats it that way, so the saved file is exactly what the preview shows.
The order matters: turn first, then mirror
When you use a turn and a mirror together, the order changes the result. This tool always turns first and mirrors after, and the stage preview follows the same order. That means what you see is what you get.
A short example shows why. Take a video with a person walking in from the left. Turn it 90° clockwise, then mirror it left to right. The mirror is applied to the turned picture, so it swaps the sides of the new, tall frame. If the mirror had been applied first, the final picture would be different.
Once the clip looks right, you may want to frame or size it. Crop video removes the edges, and the resize tool puts it at a platform size, such as the YouTube video size of 1920×1080 or the square Instagram video size of 1080×1080.
Rotate video online without uploading it
This video rotator re-draws the video on your own computer, inside the browser tab. It is never uploaded, and the server does no video work. It opens MP4, MOV, MKV, WebM and M4V files, and the result is saved as a new MP4 whose file name ends with _rotated.
- Free, with no account and no watermark.
- Video tools are not counted in the free daily limit, which applies to document conversions only.
- Works in current Chrome, Edge and Firefox.
- Most videos have no size limit. A few files, such as certain AVI or WMV videos, take longer and can be up to 2 GB.
Drop in several clips and they are all turned and mirrored the same way, which saves time when a whole batch was filmed on its side. Once a batch is upright, you can size it for a Reel or a TikTok at the Instagram Reels size of 1080×1920.
Turn your video the right way up
To rotate video, start from the 90° clockwise the tool opens with and press Turn left or Turn right until your picture stands upright on the stage. Add Mirror left to right or Flip upside down only if you need them, and check the Result line. The turn always happens first and the mirror after, so the preview matches the file.
It is free, has no watermark, and nothing leaves your device. Drop your video in the tool above and press Rotate.
