Rotate Video Online — Fix Orientation Free

How to Rotate Video Online

Rotating a video is one of the most basic yet most commonly needed editing operations. Anyone who has ever recorded video on a smartphone has encountered the problem of sideways or upside-down footage. This free online video rotation tool lets you fix orientation with just a few clicks.

Everything is processed directly in your browser using the Canvas API and MediaRecorder. Your video never leaves your device, ensuring complete privacy. Simply upload your video, choose a rotation angle, preview the result in real-time, and download the corrected file.

Rotation vs Flip — What’s the Difference?

Many people confuse rotation and flipping. Understanding the difference is essential for choosing the right operation:

• Rotation: Turns the entire video around its center point. A 90-degree rotation swaps width and height. Use when video is sideways or upside-down.
• Horizontal Flip: Creates a mirror effect from left to right. Dimensions remain unchanged. Use when selfie/front-camera video appears mirrored (text is backwards, left hand appears as right hand).
• Vertical Flip: Mirrors the video from top to bottom. Rarely used alone, but useful when combined with a 180-degree rotation.

You can combine rotation and flip operations for complex corrections. For example, a selfie video filmed sideways needs both a 90-degree rotation and a horizontal flip to correct both the orientation and the mirror effect.

Fix Sideways Video from Phone

The most common problem is video playing sideways after recording on a phone. This happens because the phone's orientation sensor (gyroscope) fails to detect the correct direction when you start recording. Common scenarios include:

• Rotating the phone from portrait to landscape after pressing the record button
• Phone lying flat on a table where the gyroscope cannot determine orientation
• Screen rotation lock is enabled but you physically hold the phone in landscape

To prevent this issue, always hold your phone steady for 1-2 seconds before pressing record so the sensor has time to detect the correct orientation. Alternatively, enable screen rotation lock before filming.

When fixing existing footage, the key is identifying which direction the video needs to go. If people in the video have their heads pointing to the left side of the screen, you need a 90-degree clockwise rotation. If heads point right, use 90 degrees counter-clockwise. If everything is upside-down, a 180-degree rotation does the trick.

Rotate for Social Media Platforms

Each social media platform has specific orientation requirements. Uploading a video with the wrong orientation results in black bars, automatic cropping, or distorted display. Here is what each major platform expects:

• Instagram Reels/Stories, TikTok: Require portrait 9:16 format (1080×1920 pixels). Landscape video will be shrunk with black bars above and below.
• YouTube: Standard is landscape 16:9 (1920×1080). Portrait video gets pillarboxed with black bars on the sides, though YouTube Shorts accept 9:16.
• Facebook: The most flexible platform, accepting landscape, portrait, and square. Square 1:1 takes up the most screen space on the mobile feed.
• Twitter/X: Landscape 16:9 is preferred. Portrait videos get cropped to near-square in the feed view.

After rotating your video to the correct orientation for your target platform, consider using our Compress Video tool to optimize the file size before uploading. Smaller files upload faster and may avoid platform size limits.

Common Rotation Mistakes

Here are the most frequent errors people make when rotating video and how to avoid them:

• Rotating the wrong direction: Choosing 90° CW instead of CCW (or vice versa) results in an upside-down video. Always use the live preview to verify before downloading.
• Ignoring EXIF metadata: Some videos contain rotation metadata that tells players to auto-rotate. The video file itself may be sideways, but a smart player shows it correctly. When you upload to a platform that reads this metadata, it may rotate the video an extra time, making it wrong again.
• Multiple re-encodings: Every time you process a video, quality degrades slightly due to re-encoding. Try to get the rotation right on the first attempt. This tool outputs WebM with VP9 at high bitrate to minimize quality loss.
• Forgetting aspect ratio changes: A 90-degree rotation swaps width and height. A 1920×1080 landscape video becomes 1080×1920 portrait. If your target platform requires landscape, you may need to crop or add padding after rotating.
• Not keeping the original: Always retain a copy of the unrotated original. This tool creates a new file and never modifies your source.
