Rotate Video

Rotate a video 90° left or right or 180°, or mirror it, in your browser. Lossless for MP4 and MOV, with a preview. Free, no sign-up, nothing uploaded.

Runs in your browser. Your files are never uploaded. How it works

Rotate Video turns a sideways or upside-down video the right way round: 90° right, 90° left or 180°. You can also mirror it, left to right. For MP4 and MOV files there is a fast, lossless method that keeps the original quality; or the frames can be re-encoded so the video plays the right way round in every app and site. A preview shows the turn before you save. The video stays on your device.

How to rotate a video

  1. Choose a video: MP4, MOV, WebM or MKV.
  2. Pick ↻ 90° right, ↺ 90° left or 180°. Tick Mirror (flip left to right) if you need it.
  3. Check the preview of the turn.
  4. Choose the Method: Fast and lossless or Re-encode the frames.
  5. Click Rotate video, then download the result.

Which turn do I need?

The video looks Choose
Lying on its left side (top points left) 90° right
Lying on its right side (top points right) 90° left
Upside down 180°
Text reads backwards, like in a mirror No turn, with Mirror ticked

The preview shows the result straight away, so if the first choice is wrong, simply pick the other one.

Two methods

Fast and lossless (MP4 and MOV; players apply the turn). Video files can carry a rotation note, the same way phones record portrait videos. This method writes that note and copies the video and sound exactly as they are, without re-encoding. It takes seconds even for long videos, and the quality and file size stay the same. Most players follow the note.

Re-encode the frames (works in every app and site). Every frame is turned and the video is encoded again. It takes longer, but the picture itself is now the right way round, so it also plays correctly in the few apps and editors that ignore the rotation note. Mirroring and WebM or MKV files always use this method. The result is MP4 with H.264 video and AAC sound, or WebM where the browser cannot encode MP4.

Start with the fast method. If the video still plays sideways in the app you use, rotate the original again with re-encoding.

Why videos end up sideways

Phones decide between portrait and landscape from how you hold them when recording starts. Begin with the phone flat on a table or turn it after pressing record, and the video can be saved the wrong way. Some cameras, drones and older apps also ignore orientation altogether. Webcam and selfie videos are often mirrored, which makes writing in the picture read backwards: use Mirror to fix it.

Good to know

  • iPhone videos in HEVC cannot be read in some browsers. If yours will not open, try a recent Chrome or Edge, or Safari on a Mac.
  • Portrait videos for social media: after turning, crop to the shape you need with Crop Video.

Frequently asked questions

How do I rotate a video?

Choose the video, pick 90° right, 90° left or 180°, and check the preview. Choose the method, click Rotate video and download the result.

Does rotating lower the quality?

Not with Fast and lossless. For MP4 and MOV files the turn is stored in the file and the video and sound are copied as they are, so nothing is re-encoded and the quality stays exactly the same. Re-encode the frames makes a new copy at high quality, which can lose a little detail.

Why does my rotated video still play sideways somewhere?

The fast method stores the turn as a note in the file, and a few apps and websites ignore that note. Rotate the original again with Re-encode the frames: the picture itself is then turned and plays the right way round everywhere.

Can I flip a video like a mirror?

Yes. Tick Mirror (flip left to right), with or without a turn. Mirroring always re-encodes the frames, because the picture itself has to change.

Is my video uploaded?

No. The video is processed in your browser, on your device. Nothing is sent to a server.

Which formats work?

MP4, MOV, WebM and MKV can be opened. The fast lossless method works for MP4 and MOV. WebM and MKV files are re-encoded, and the result is MP4 or, in browsers that cannot encode MP4, WebM.
