Get a video the right way up
Every orientation
90° left or right for a video lying on its side, 180° for an upside-down video, mirror for a reversed image.
Preview before exporting
Check the result before starting the processing: you know right away if it's the right way up.
MP4 with sound
The video is saved as MP4, the format that plays everywhere, and its soundtrack is kept.
No upload
Processing happens in your browser with FFmpeg: your videos never leave your device.
Rotate a video filmed sideways
The phone was held flat when recording started, you turned it partway through, or the video shows up sideways once transferred to your computer: it's one of the most common problems with smartphone videos. Rotate it 90° to the left or right to straighten it, or 180° if it's completely upside down. The preview shows you the right choice before any processing.
Flip a video like a mirror
Depending on the settings, a phone's front camera or a webcam can record a reversed image: text, a logo, or a sign then appears backward, as in a mirror. The mirror effect flips the video horizontally to set everything right. It's also handy for reversing a dance or workout tutorial, so you can copy the moves on the same side as the person on screen.
A video the right way up, everywhere
Some players only rotate the video on screen: it's back in the wrong orientation as soon as you send it or open it elsewhere. Here, the video is re-encoded with FFmpeg, right in your browser: the rotation is applied to the image itself, and the resulting MP4 displays correctly on a phone, on a computer, or in a messaging app. To keep only one part, then use “Cut / Trim Video”; to make it smaller before sending it, “Compress Video”.
Frequently Asked Questions
How do I fix a video that was filmed upside down?
Add it and choose 180°: the preview instantly shows it the right way up. Start the export, then download the corrected MP4.
Does a 90° rotation make the video vertical?
Yes: width and height are swapped, so a horizontal video becomes vertical, and vice versa. The tool rotates the whole image; it doesn't crop a horizontal video to portrait format.
Is the sound kept?
Yes, the soundtrack is kept in the downloaded MP4. To extract only the audio from a video, use “Convert MP4 to MP3”.
Does rotating a video reduce its quality?
To actually rotate the image, the video has to be re-encoded as MP4. The quality stays very close to the original; this re-encoding is what takes a few seconds to a few minutes, depending on the length.
Is my video uploaded to a server?
No, everything happens in your browser thanks to FFmpeg; only the conversion engine is downloaded on first use. It's free, with no account and no watermark.
