About Flip Video
This free tool flips a video. Press Mirror to swap left and right, or Flip upside down to turn the picture over top to bottom. The preview changes at once, so you see the result before anything is made. Then press Save video and download the MP4.
The most common reason: a selfie or webcam video where the text on your shirt or on a sign reads backwards. One press of Mirror fixes it.
Everything happens in your browser. Your video is never uploaded.
Features
- Mirror left to right — the fix for backwards text in selfie and webcam clips
- Flip upside down — top and bottom swap, left and right stay
- Instant preview — the picture flips as you press, with no waiting
- Turn buttons too — 90° left or right and 180°, in the same save
- Sound copied, not changed — the audio is not re-encoded
- MP4 out with fast start, ready for phones and the web
- Private — no upload, no account, no watermark
Mirror, flip or turn: which one do you need?
| What is wrong with the video | Button to press | What changes |
|---|---|---|
| Text reads backwards (selfie, webcam) | Mirror | Left and right swap |
| You want a "mirror view" for dance or sport practice | Mirror | Left and right swap |
| Top and bottom are swapped, but left and right are correct | Flip upside down | Top and bottom swap |
| The camera was mounted upside down (dashcam, action camera) | Turn 180° | Top/bottom and left/right swap |
| The video is on its side | Turn left 90° or Turn right 90° | Width and height swap |
Mirror and Flip upside down together give the same picture as Turn 180°. A flip never changes the size of the video: a 1920×1080 video stays 1920×1080. Only a 90° turn swaps width and height.
Why selfie videos come out mirrored
When you film yourself, the screen shows you like a mirror, because that feels natural: you raise your right hand and the hand on the right side of the screen moves. Many phones save the photo or video the other way, the way other people see you. But some apps, webcam programs and video calls save exactly what the screen showed — the mirror view. Then every word in the picture is backwards.
Nothing is wrong with the video itself. It only needs one horizontal flip, and that is what Mirror does.
What people use it for
- Selfie and webcam clips with backwards text
- Dance, yoga and workout videos — a mirrored teacher is easier to follow: when they move right, you move right
- Screen and camera recordings for a lesson, where the board or the paper reads backwards
- Dashcam and action camera footage from a mount that was upside down
- Creative edits — a mirrored copy of a clip for a symmetric effect
Good to know
- The first save downloads the video engine (about 30 MB). That happens once per visit.
- Saving takes about 1 to 3 times as long as the video. A one-minute clip takes one to three minutes on a laptop, longer on a phone.
- The picture is re-encoded (H.264), so there is a very small quality loss, as with any video edit. The sound is copied untouched.
- If a file will not open, convert it first with Video Converter, then flip the MP4.
Frequently asked questions
How do I mirror a video?
Drop the video on the box, press Mirror (left ↔ right), check the preview, and press Save video. When it is ready, press Download. The new MP4 is the mirror image of the old one.
How do I unmirror a selfie video?
The same way: press Mirror. Mirroring twice gives back the original, so a mirrored selfie becomes a normal video.
What is the difference between flip and rotate?
A flip makes a mirror image: the picture turns over, like a page. A rotation turns the picture around its middle, and nothing is mirrored. Text stays readable after a rotation, but not after a flip. For a sideways phone video use Rotate Video.
Does flipping lower the quality?
Very little. The picture is encoded again as H.264 at a good quality setting, and the sound is copied without change. On a phone screen you will not see a difference.
Can I flip only part of a video?
No, the whole video is flipped. To flip one part, cut that part out first with Trim Video, flip it, and join the pieces with Merge Video.
Is my video uploaded?
No. The video is flipped inside your browser with ffmpeg. It never leaves your device.
