Rotate or flip a video

Drop a video, pick a turn or a mirror, and download it. Turning an MP4 or a MOV only changes the flag that says which way up it plays, so it takes seconds and nothing is re-encoded.

Your file never leaves this device. Everything runs in your browser.

How it works

  1. Drop your video.
  2. Pick a turn or a mirror and check the preview.
  3. Press Rotate and download the video.

Questions

Does rotating lose quality?

Not for an MP4 or a MOV. A turn only changes the rotation flag, the setting that tells a player which way up to show the video, and every frame is copied as it was. A mirror, or a turn of a WebM or an MKV, is re-encoded to H.264 at high quality.

Why is a turn so fast?

Because nothing is decoded. Phones record what the camera sensor sees and store which way up it goes as a flag, and this tool rewrites that flag. A file of any length takes seconds.

Why is a mirror re-encoded?

A mirror is drawn into every frame rather than written as a flag, so it looks the same in every player and every app you upload to. That takes a re-encode, for videos up to 15 minutes.

What format do I get?

A turned MP4 stays an MP4 and a MOV stays a MOV. Anything re-encoded comes back as an MP4 with H.264 video and AAC sound: WebM and MKV have no rotation flag players honour.

Does my video get uploaded?

No. It's turned in your browser, on your device.

Which browsers does it work in?

A turn of an MP4 or a MOV needs no encoder, so it works in current Chrome, Edge, Safari and Firefox. A mirror or a re-encode makes H.264 video, which Chrome, Edge and Safari can.
