Free Tool
Fix sideways or upside-down video — free, in-browser
Rotate video 90°, 180°, or 270°. No upload, no software to install.
The problem
Phone videos sometimes record sideways or upside-down when the orientation sensor misfires. Video editing software re-encodes unnecessarily for a simple rotation. Online tools ask you to upload to their servers.
The NSS solution
NSS Video Rotate uses canvas transform to rotate your video and re-encodes it with the correct orientation. 90° CW, 90° CCW, or 180°. Runs entirely in your browser.
How to use it
- 1
Fix phone video filmed sideways
When a phone's orientation lock fails, the video records in landscape even though you were holding the phone vertically. Rotate 90° to correct it.
- 2
Flip upside-down recordings
Action cams, mounted cameras, and some screen recordings can produce upside-down footage. Use 180° rotation to correct it instantly.

Reformat for vertical platforms
Sometimes it's easier to rotate a horizontal clip 90° and then canvas-extend to 9:16 than to re-shoot in portrait orientation.
Step-by-step guide
- 1
Choose your rotation
90° Clockwise, 90° Counter-clockwise, or 180°. 90° rotations also swap width and height.
- 2
Upload your video
Drop or browse to upload. The video plays through at real time during rotation.
- 3
Download the corrected video
The output file has the correct orientation permanently encoded — not just a metadata rotation flag.
Common questions
Does this just set a rotation metadata flag?
No — the video is re-encoded with the rotation applied to every frame. The resulting file plays with the correct orientation in all players, not just those that read rotation flags.
Will the output be cropped?
No. For 90°/270° rotations, the width and height swap. A 1920×1080 video becomes 1080×1920 after a 90° rotation — no cropping.
