Rotate & Flip Video

Rotate & Flip Video fixes clips that play the wrong way round: a phone video that comes out sideways, a recording that is upside down, or a selfie video that is mirrored. Turn it left or right by 90°, by 180°, mirror it left to right or flip it upside down, and watch the preview change as you go.

There are two ways to save. Re-encode redraws every frame the new way round, so the video looks right in every player, app and website. It takes a little longer and costs a tiny bit of quality. Rotation flag only is the quick way: MP4 and MOV files carry a small flag that tells players which way up to show the picture, and this option changes just that flag. The frames are copied untouched, so it takes a second and loses nothing.

The catch, which most tools don’t mention: some players ignore that flag. Phones, QuickTime, VLC and web browsers obey it, but some older players, smart TVs and upload sites don’t. That is often why a video looks fine on your phone and sideways elsewhere. When in doubt, re-encode.

Your video never leaves your device; there is no sign-up and no watermark.

1. Tap “Choose a video” or drop one onto the box. MP4, MOV, WebM and MKV all work.
2. Press “Turn left”, “Turn right”, “Turn 180°”, “Mirror left–right” or “Flip upside down” until the preview looks right. “Reset” starts again.
3. Under “How to save it”, keep “Re-encode” for a video that is right everywhere, or pick “Rotation flag only” for an instant, lossless change to an MP4 or MOV.
4. Press “Save turned video”, check the result as it plays, then press “Download video”.

• Turn 90° left or right, 180°, mirror left–right and flip upside down, in any combination.
• A live preview that plays and scrubs, showing exactly how the saved video will look.
• Re-encode bakes the new orientation into every frame, saved as MP4 (H.264 + AAC) or, where a browser can’t write that, WebM.
• Rotation flag only: an instant, lossless change for MP4 and MOV files, keeping the original picture and sound bytes.
• Tells you when your file already carries a rotation flag, the usual reason a clip looks sideways in some players.
• Keyboard shortcuts: L turns left and R turns right.
• Keeps the sound, or drops it if you untick “Keep the sound”.

• If a video looks right on your phone but sideways on a computer or TV, it has a rotation flag that player ignores. Re-encode fixes it for every player.
• Mirroring always re-encodes. Players disagree about mirror flags, and Safari even shows them upside down, so the tool doesn’t offer a mirror flag.
• Front-camera videos often look mirrored compared with what you saw while filming. “Mirror left–right” puts writing the right way round again.
• The rotation flag works only for MP4 and MOV files. WebM and MKV have no such flag, so they always re-encode.
• Turning a video 90° swaps its width and height: a 1920×1080 clip becomes 1080×1920.
