Rotate Video

About Rotate Video

Easily rotate your videos 90, 180, or 270 degrees (clockwise or counter-clockwise) with our Free Online Rotate Video Tool. This tool operates entirely within your web browser using FFmpeg.wasm, meaning your video files are processed directly on your device and are never uploaded to any server. Your privacy is guaranteed.

Simply upload your video, select the desired rotation angle (90° Clockwise, 90° Counter-Clockwise, or 180°), and click 'Rotate Video'. You can preview both the original and the rotated result before downloading the modified video. The original audio track is preserved in the rotated video.

Features:

• Client-Side Processing: Uses FFmpeg.wasm for secure, in-browser video rotation. Your files stay private.
• Multiple Video Formats: Supports common video types like MP4, WEBM, MOV, AVI (depending on browser & FFmpeg support).
• Rotation Options: Rotate 90° Clockwise, 90° Counter-Clockwise, or 180°.
• Audio Preservation: Keeps the original audio track in the rotated video.
• Dual Preview: See your original video and a preview of the rotated version side-by-side (after processing).
• Easy Download: Download the rotated video directly to your device (output as MP4).
• Progress Tracking: Monitor the rotation process with a real-time progress bar.

How to Use:

1. Load Engine: Wait for the video processing engine (FFmpeg) to load (progress bar shown).
2. Upload Video: Drag and drop your video file onto the upload area or click "Select Video" to browse your device.
3. Preview Original: Your uploaded video will appear in the "Original Video" preview player.
4. Choose Rotation Angle: Select the desired rotation from the dropdown menu (e.g., "90° Clockwise").
5. Rotate: Click the "Rotate Video" button.
6. Wait & Preview: The progress bar will show the rotation status. Once complete, the rotated video (with audio) will appear in the "Rotated Video Preview" player. Any errors will be displayed in the status area.
7. Download: Click the "Download Rotated Video" button to save the result.
8. Share (Optional): Click "Share Tool" to share the tool's link.

Note: Video processing happens entirely in your browser. Rotating larger or longer videos may take more time and consume more system resources (CPU/Memory).

Quick Answer

To rotate a video online, upload the file to this page, choose 90° clockwise, 90° counter-clockwise or 180°, click Rotate Video, and download the MP4. Everything runs in your browser through FFmpeg.wasm, so nothing is uploaded, there is no watermark and no account is needed. Use 90° when a phone recorded a clip sideways, and 180° when the footage came out upside down. A 90° or 270° rotation swaps the frame's width and height, turning a 1920×1080 landscape clip into a 1080×1920 vertical one.

Common Use Cases

Fixing phone video recorded sideways

If the phone was held at the wrong angle or the orientation lock was on, the clip plays rotated on a computer even though it looked fine on the phone. A 90° rotation bakes in the correct orientation so every player shows it upright.

Converting landscape footage to vertical for Shorts and Reels

Rotating a landscape clip 90° produces a vertical frame that fits TikTok, Instagram Reels and YouTube Shorts without letterboxing.

Correcting upside-down action-camera or drone footage

Cameras mounted inverted on a helmet, roll bar or gimbal record a 180° image; one pass here puts it right way up.

Repairing broken rotation metadata

Some editors and messaging apps ignore the rotation flag stored in an MP4 file. Rotating the actual pixels removes the ambiguity, so the video looks the same everywhere.

Preparing footage for editing

Fixing orientation before importing into an editor saves re-framing every clip on the timeline.

Frequently Asked Questions

How do I rotate a video 90 degrees?

Upload the video, select 90 degrees clockwise or 90 degrees counter-clockwise from the rotation dropdown, and click Rotate Video. The tool applies FFmpeg's transpose filter to every frame. When it finishes, preview the result and download the MP4.

Does rotating change the video's dimensions?

A 90 or 270 degree rotation swaps width and height, so a 1920x1080 clip becomes 1080x1920. A 180 degree rotation keeps the same dimensions and simply turns the picture upside down.

Is my video uploaded anywhere?

No. Rotation runs entirely in your browser using FFmpeg compiled to WebAssembly. The file is read from your disk into browser memory and the result is written straight back to your device, so no video data is transmitted to any server.

Will rotating reduce the quality of my video?

Rotation moves pixels without resampling them, so the transform itself is lossless, but the output has to be re-encoded to MP4. The tool uses a high-quality encode, and the loss is not noticeable in normal viewing. Resolution, frame rate and duration are otherwise unchanged.

Why does my video look correct on my phone but sideways on my computer?

Phones usually store the clip in the sensor's native orientation and add a rotation flag to the file's metadata. Players that honour the flag show it upright; players and editors that ignore it show it sideways. Rotating the pixels with this tool removes the dependency on that flag.

Is the audio kept when rotating?

Yes. The original audio track is carried over and stays in sync. Only the video stream is transformed.

What is the difference between rotating and flipping?

Rotating turns the whole frame by a multiple of 90 degrees. Flipping mirrors the frame across an axis, which reverses left and right (or top and bottom) without turning it. Use rotate for wrong orientation and flip for mirrored selfie footage.

Is there a file-size limit?

No hard limit is imposed, but processing runs in your browser's memory. Very long or very high-resolution files may exhaust the tab. If a large file fails, try compressing or trimming it first, or use a desktop browser with more available RAM.

Which rotation method should I use if another player ignores the rotation flag?

Choose Rotate the picture (plays the same everywhere) if you need the orientation to be applied to the video image itself. The instant method sets an orientation flag and is described as lossless for MP4 and MOV, but a player that does not read that flag may show the picture sideways. Preview the exported file in the app where you plan to use it.

How do I fix a video that looks upright on my phone but sideways after sharing it?

Choose the rotation that makes the preview upright, then use Rotate the picture so the change is applied to the image and plays the same way across players. Some devices and apps use orientation metadata when displaying a video, and another player may interpret it differently. Check the rotated preview and the downloaded file in the app where you plan to share it.

Will rotating a video also reverse its left and right sides?

No. Rotation turns the picture by the selected angle; it does not mirror or flip the image. If text or a person appears backward, that is a reflection issue rather than an orientation issue, and the form lists rotation controls rather than a flip option. Choose the angle that turns the footage upright, then check the preview before downloading.
