The Video Rotator rotates your footage by 90, 180, or 270 degrees to fix clips that recorded sideways or upside-down. Pick an angle, and the tool permanently re-orients the actual video frames so the file plays the right way up on every device and player — phones, social platforms, editors, and TVs — not just one that happens to honor a rotation flag.

Rotation runs entirely in your browser using ffmpeg.wasm (FFmpeg compiled to WebAssembly) with the transpose filter. Your video is never uploaded to a server — it is read, rotated, and saved locally on your own device, so the footage stays completely private. It is free with no signup, and it is ideal for anyone fixing phone clips shot in the wrong orientation, GoPro or dashcam footage, or videos that look correct on a phone but turn sideways once shared.

Why use this tool

Permanent, true rotation

The transpose filter rotates the actual pixels, so the fix is baked into the file and looks correct on every player and platform — not just devices that read a rotation flag.

100% private, nothing uploaded

Your video is rotated locally with WebAssembly and never sent to a server, so even personal or sensitive footage stays entirely on your device.

Audio stays untouched

Sound is stream-copied without re-encoding, so your audio track is preserved at its original quality with no loss while the picture is rotated.

No software or signup

Everything runs in your browser for free with no account, no app install, and no watermark, on Windows, Mac, Linux, or Chromebook.

How to use the Video Rotator

  2. Choose a rotation angle

    Select 90 degrees, 180 degrees, or 270 degrees to correct the orientation of your footage.

  3. Rotate the video

    Click "Rotate Video" and ffmpeg.wasm re-orients the frames locally in your browser.

  4. Preview the result

    Check the rotated preview to confirm the video now plays the right way up before saving.

  5. Download the file

    Download the rotated MP4 to your device, ready to share or upload anywhere.

Popular use cases

  • Fixing a phone clip that recorded sideways and turns 90 degrees the moment you upload it to YouTube or Instagram.
  • Flipping upside-down footage from an action camera, drone, or dashcam mounted in an inverted position.
  • Correcting a video shot in portrait when it should be landscape (or the reverse) before sharing or editing.
  • Re-orienting old camcorder or converted clips so they display upright on a TV or in a video editor that ignores rotation metadata.

Frequently asked questions

Is the Video Rotator free to use?
Yes, the Video Rotator is completely free with no signup, watermark, or usage limits. You can rotate as many videos as you want, as often as you want, at no cost.
Are my videos uploaded to a server when I rotate them?
No. The Video Rotator processes everything locally in your browser using ffmpeg.wasm (WebAssembly). Your video file never leaves your device and is not uploaded anywhere, which keeps your footage fully private.
What video formats can I rotate?
You can rotate MP4, MOV, AVI, MKV, WebM, FLV, WMV, and M4V files, along with most common video formats. The rotated video is exported as an MP4 (H.264) file for broad compatibility.
What rotation angles are available?
You can rotate clockwise by 90 degrees, flip 180 degrees (upside-down to right-side-up), or rotate 270 degrees (equivalent to 90 degrees counter-clockwise). These cover every common orientation fix for sideways or inverted footage.
Will rotating my video reduce its quality?
Rotation re-encodes the video stream with H.264, so there is a small, usually unnoticeable quality change from one encoding pass. The audio is stream-copied unchanged, so sound quality is preserved exactly with no loss.
Is there a file size limit?
You can rotate videos up to around 1 GB. Larger files depend on your device's available memory, since all processing happens in your browser's RAM rather than on a server.
How long does it take to rotate a video?
Most short clips rotate in well under a minute. Because rotation re-encodes the video frames, longer or higher-resolution files take more time, and overall speed depends on your device's processor.
Why does my video look sideways everywhere even though it plays fine on my phone?
Many phones store a rotation flag in the file's metadata rather than rotating the actual pixels, and not every player or platform reads that flag. This tool physically rotates the video frames, so the corrected orientation is baked into the file and displays correctly everywhere.
