About the Video Flipper

VideoKit's Online Video Flipper is built on WebCodecs technology, letting you mirror videos right in your browser. It supports horizontal flip (left-right mirror) and vertical flip (up-down mirror), with a real-time preview so you can see the result before processing.

Frequently Asked Questions

What's the difference between horizontal and vertical flip?

Horizontal flip swaps left and right, like a mirror image. Vertical flip swaps top and bottom, turning the image upside down. Choose whichever matches your needs.

Will flipping affect video quality?

By default we use high-quality encoding parameters, so quality loss is minimal and typically invisible to the naked eye. The flip requires re-encoding the video to properly apply the mirror effect.

Will my video files be uploaded?

No. All video processing happens locally in your browser. Files are never uploaded to any server, and your video data stays entirely under your control.

Which video formats are supported?

Reads most common video formats (MP4, WebM, MOV, MKV, AVI, and more) and outputs in MP4, WebM, or MOV. For the best compatibility, we recommend a recent browser (Chrome or Edge).
