What Is Video Rotator?

A Video Rotator is a software application designed to adjust the orientation of video files by rotating them by specific angles, typically 90, 180, or 270 degrees. It is commonly used by social media creators, videographers, and smartphone users who need to fix sideways phone recordings or correct upside-down videos. One specific problem it solves is allowing users to rotate video online without having to upload their files to a server, thus maintaining control over their data.

The tool is particularly useful for fixing issues with video orientation that occur during recording, such as when a phone is held in the wrong position. What makes this tool different is its ability to use Canvas transformations to rotate each frame of the video during processing, producing a properly oriented output video. It also provides a real-time preview of the rotated result before processing, allowing users to see how their video will look after rotation.

It uses a MediaRecorder to capture the rotated video stream and supports various rotation angles, including 90, 180, and 270 degrees. All processing happens locally in the browser, meaning that video files never leave the user's device, addressing concerns around data privacy and security. This approach enables users to rotate videos without uploading them, making it a convenient solution for those who need to fix their video orientation quickly and securely.

Why Use Video Rotator?

  • Fix sideways or upside-down phone recordings
  • Real-time rotation preview before processing
  • No file uploads — complete privacy
  • Simple one-click rotation in 90° increments

Common Use Cases

Fix Phone Videos

Correct the orientation of phone recordings that were captured sideways.

Portrait to Landscape

Rotate vertical videos to horizontal orientation or vice versa.

Upside-Down Fix

Fix videos that were accidentally recorded upside down.

Creative Effects

Adjust video orientation for artistic or presentation purposes.

Technical Guide

The Video Rotator uses Canvas 2D transformations to rotate video frames. When rotating by 90° or 270°, the canvas dimensions are swapped (width becomes height, height becomes width). The rendering context's transform is set using ctx.translate() to move the origin and ctx.rotate() to apply the rotation in radians. Each frame from the video is drawn onto the transformed canvas, producing the rotated output. The canvas stream (with swapped dimensions for 90°/270° rotations) is combined with the audio stream and fed to MediaRecorder. The tool handles the dimensional changes properly to ensure no stretching or cropping occurs during rotation.

Tips & Best Practices

  • 1
    For 90° and 270° rotations, the video dimensions are swapped (width ↔ height)
  • 2
    Preview the rotation before processing to confirm the correct direction
  • 3
    180° rotation is useful for upside-down videos
  • 4
    Rotation does not affect video or audio quality beyond normal re-encoding

Frequently Asked Questions

Q Why is my phone video sideways?
Some phone recordings embed rotation metadata instead of rotating the actual frames. This tool physically rotates the frames to fix the orientation.
Q Does rotation affect quality?
The rotation itself is lossless, but re-encoding the video introduces minor compression artifacts typical of any video processing.
Q Does this tool upload files to a server?
No. All processing happens locally in your browser. Your files stay completely private.
Q Can I rotate by custom angles?
This tool supports 90°, 180°, and 270° rotations. For arbitrary angle rotation, video editing software would be needed.
Q Does it preserve audio?
Yes, the audio track is fully preserved in the rotated video.
