Rotate Video Online Free – Fix Sideways and Upside-Down Videos

Permanently fix video orientation by rotating 90, 180, or 270 degrees. The rotation is written into the pixel data, not just the metadata. Your video will play correctly on every device, app, and platform. No uploads, no watermarks, and no software.

Why Videos Play Sideways (And How This Fixes It)

Phones and cameras don't always store video in the orientation you see. They record in a fixed orientation and add a metadata tag telling players how to rotate it. The problem: many platforms and editors ignore that tag and play the raw data — which looks sideways.

This tool doesn't just change the metadata tag. It rotates every single frame's pixel data and writes a new file. The result plays correctly everywhere because the orientation is baked into the actual image, not stored as a hint that players can ignore.

The rotation is permanent. Your original file isn't modified — you get a new MP4 with the corrected orientation.

When This Fixes Your Problem

Sideways phone recordings

You started recording in portrait, rotated to landscape, and now the video plays sideways on YouTube. Rotate 90 degrees clockwise. The output fills the player correctly without viewers tilting their heads.

Upside-down action camera footage

Helmet or handlebar mounts sometimes require upside-down camera placement. The footage looks inverted. Rotate 180 degrees and the scene appears upright.

Metadata tags that editors ignore

Premiere Pro and DaVinci Resolve sometimes import phone footage sideways because they ignore rotation metadata. Rotating the file before importing fixes it permanently.

Vertical digital signage

Retail screens are often mounted vertically. Rotate a 1920x1080 landscape video 90 degrees and it becomes 1080x1920 portrait — perfect for vertical displays.

Standardizing mixed-orientation clips

Some clips shot horizontal, some vertical. Rotate them all to match before editing. Your timeline stays consistent and you avoid per-clip rotation fixes in your editor.

Not sure which direction? Try 90° first. If it's still wrong, try 270°. The preview shows the result before you download.

How to Rotate Your Video

1

Upload your video

Select or drag your file. It stays on your device — no server upload. The preview shows the current orientation so you can see what needs fixing.

2

Choose rotation angle

Click 90°, 180°, or 270°. For sideways video, start with 90° clockwise. For upside-down footage, use 180°. The preview updates to show the result.

3

Rotate and download

Click rotate and wait. Processing time depends on video length. Keep the tab open. When done, preview the result and download the corrected file.

Frequently Asked Questions

Load your video into the tool, select the 90-degree clockwise or counter-clockwise option, and click Rotate Video. The encoder rewrites every frame in the new orientation and produces a standard MP4 file. The rotation is burned into the pixel data, not stored as a metadata tag, so the file plays correctly on every platform. No watermarks are added because all processing happens on your device at no cost.
Smartphones record video based on the position of the device at the moment you start recording. If the gyroscope detected landscape mode, the video data is stored horizontally. Some phones attach a metadata rotation tag that tells compatible apps to display it upright, but many websites, video editors, and social platforms ignore that tag and play the raw data orientation instead.
Rotating 90 degrees clockwise spins the video one quarter turn to the right. The top edge of the original image becomes the right edge of the output. Rotating 270 degrees clockwise produces the opposite result, which is the same as rotating 90 degrees counter-clockwise. The top edge of the original image becomes the left edge of the output.
Yes. When you rotate a 1920x1080 video by 90 degrees, the output dimensions become 1080x1920 because the width and height swap. The encoder recalculates the pixel grid to fit the new orientation. A 180-degree rotation keeps the same 1920x1080 dimensions because the image flips upside down without swapping the sides.
No. This tool rotates video in 90-degree increments around the center axis. A mirror flip inverts pixels horizontally or vertically, which is a different operation. You would need a video editor that supports horizontal or vertical flip to achieve a mirror image effect.
The rotation is permanent. The encoder reads every frame, rotates the pixel grid to the new orientation, and writes the result into a new MP4 file. This is different from apps that add a rotation metadata tag. A metadata tag only works if the player reads and respects it. This tool changes the actual pixel data, so the video displays correctly in every player and platform regardless of metadata support.
