About Rotate Video
Rotate Video turns a video a quarter, half, or three-quarter turn, and can mirror it left-right or top-bottom, with or without a rotation. It works two ways. "Compatible everywhere", the default, turns the picture itself on our video service and returns an MP4 that plays upright in any player. For MP4, MOV, M4V, 3GP, and 3G2 files, "Instant, lossless" only rewrites the rotation setting stored in the file, in your browser, so its size, quality, and format stay the same. A mirror always goes through the video service.
How to rotate or flip a video
- 1Choose or drop a video file; a preview appears.
- 2Click an angle button (90°, 180°, or 270°) or "No rotation", and "Mirror ⇆ (left-right)" or "Flip ⇅ (top-bottom)" if needed: the preview turns with your choice.
- 3For an MP4, MOV, M4V, 3GP, or 3G2 file, choose "Compatible everywhere" or "Instant, lossless" under "How to rotate".
- 4Click "Rotate video"; with "Compatible everywhere" the page shows the upload and processing progress.
- 5Play the result and click "Download": an MP4, or your file's own format with "Instant, lossless".

Where your file is processed
With "Instant, lossless", nothing is uploaded: the page rewrites a few bytes of the file's header in your browser and gives the file back. With "Compatible everywhere", any mirror, or a format other than MP4, MOV, M4V, 3GP, or 3G2, the video is sent to our video service on Railway, which turns it with ffmpeg, deletes the original at the end and deletes the result once this page has downloaded it. If the rotation fails, its cleaned message, the error type, the tool name, the file type, a size range, and your browser and its version are reported to us, never the video.
Frequently asked questions
Which option should I choose?
"Compatible everywhere" when the video will be sent to others or played in the old Windows Media Player, which ignores rotation settings. "Instant, lossless" for your own viewing in Photos, QuickTime, Safari, Chrome, Firefox, VLC, Android, or the Windows 11 Media Player, which apply the setting; it keeps the exact quality and size.
Does rotating reduce quality?
No with "Instant, lossless": the picture is not re-encoded. Yes, slightly, with "Compatible everywhere" or a mirror: the turned picture is encoded again in H.264 at full resolution, at the service's high-quality setting or, if that would make it larger than the original, with stronger compression.
Is the sound changed?
No with "Instant, lossless": the sound is left as it is. With "Compatible everywhere", the first audio track is encoded again as AAC at 160 kbps and other audio tracks are dropped.
Can I rotate a WebM, MKV, or AVI video?
Yes, with "Compatible everywhere" only: these formats store no rotation setting, so the picture is turned on our video service and comes back as an MP4.
Can I rotate by 45° or another angle?
No. Only quarter turns are offered: 90°, 180°, and 270°, alone or with a mirror. A slightly tilted picture cannot be straightened with this tool.
