How to flip a video

Mirror a video online
A phone's front camera often records the picture like a mirror: the text on a T-shirt or a poster then appears backwards. Flipping horizontally puts left back on the left and right back on the right. It's also handy for a symmetry effect, for matching two shots filmed from opposite sides, or to keep a clip from being recognized as is. Upload the video, keep “Flip horizontal” checked, check the preview and download the result.
Flip vertically: turn a video right side up
A vertical flip swaps the top and bottom of the picture. It fixes a security camera or dashcam mounted upside down, or creates a reflection effect. Careful: if your video is simply upside down, what you need is a 180° rotation, which is the same as checking both mirrors at once. For a video lying on its side (filmed at 90°), use “Rotate Video” instead.
Flip, rotate, reverse: what's the difference?
Flipping (this tool) creates a mirror effect: the picture is swapped left to right or top to bottom. Rotating turns the picture a quarter or half turn, with no mirror: that's the “Rotate Video” tool. Reversing changes the playback direction: the video plays backwards, with “Reverse Video”. For a photo, “Flip Image” gives the same mirror effect.
Frequently Asked Questions
How do I mirror a video?
Upload the video, leave “Flip horizontal” checked (or choose “Flip vertical”), check the preview, then click “Flip video”. You download an MP4 with the original sound.
How do I unmirror a selfie video?
Apply the horizontal flip: the video is mirrored a second time and the text becomes readable again. The preview shows you the result before export.
My video is lying on its side: is this the right tool?
No: a sideways video needs to be rotated a quarter turn, not flipped. Use “Rotate Video”. For an upside-down video, check both mirrors, which equals a half turn.
Can I flip a video on iPhone or Android?
Yes, from Safari or Chrome, with no app: choose the video from your gallery, then download the flipped video.
Are sound and quality kept?
The sound is kept (in AAC). The picture is re-encoded in good-quality H.264, at its original resolution up to Full HD; a 4K video is saved in 1080p to stay fast in the browser.
Is my video uploaded to a server?
No. Flipping happens in your browser with FFmpeg; only the video engine is downloaded, once. It's free, with no sign-up and no watermark.
