How do I rotate a video 90 degrees?

Add your video, tap rotate left or rotate right once to turn it 90 degrees, then download. The preview shows the result before you save.

Is my video uploaded to a server?

Never. Everything runs locally in your browser. Your file never leaves your device.

Can I rotate and flip at the same time?

Yes. The rotation and flip controls combine, and the preview shows exactly how the final video will look.

Will rotating reduce the quality?

Rotating re-encodes the video at a high quality, so the result looks essentially the same as the original.

Which video formats are supported?

You can rotate MP4, MOV, MKV, WEBM and AVI files. The result is saved as an MP4.

Does the rotation stick in every player?

Yes. Sondra bakes the rotation into the video itself rather than setting a flag, so it stays corrected everywhere.

Why rotate or flip a video?

Phones often record video in the wrong orientation, so a clip that looked fine on screen ends up sideways or upside down on a computer or when uploaded. Rotating it puts the picture upright again so it plays the way you meant.

Flipping is just as handy. A horizontal flip mirrors the video, which fixes the reversed look of a front-camera selfie or lets you match the direction of a dance or workout move. A vertical flip turns the picture upside down when you need it.

Sondra bakes the rotation or flip straight into the video so it stays corrected in every player, with no watermark. It works with MP4, MOV, MKV, WEBM and AVI, and everything happens in your browser.

What you can do by rotating a video

Turning or mirroring a clip fixes a lot of everyday problems. Here are the most common ones.

Fix a sideways clip

Rotate a phone video that came out 90 degrees off so it plays upright.

Turn an upside-down video

Rotate 180 degrees to fix a clip that recorded the wrong way up.

Mirror a selfie

Flip a front-camera video horizontally so text and faces look the right way round.

Match a move

Mirror a dance or workout video to follow along facing the same direction.

Rotate video for any platform

An upright MP4 plays correctly everywhere. A few notes for the most popular places people share.

Instagram and TikTok

Rotate to portrait so your clip fills the screen instead of showing sideways.

YouTube

Fix a rotated upload once instead of relying on the viewer to tilt their head.

iPhone and Android

The corrected file plays upright in any gallery or messaging app.

Email and messaging

Send a clip that already plays the right way up on any device.

Private by design

Most online rotators upload your video to a server before turning it. Sondra does not. All the work happens inside your browser on your own device, so your video is never sent anywhere and nobody else can see it.

That also means there is no waiting for a long upload, no account to create, and no limit on how many videos you rotate. Close the tab and nothing is left behind.
