Crop video
Cut the edges off a video, to a square, a vertical shape or an exact rectangle.
Video Tools
Turn a sideways video the right way up, or mirror it, in seconds.
Your files and text are processed on your own device, inside this page. Nothing is uploaded to Dubinity or stored, and closing the tab discards it. How privacy works
Most sideways videos are not really sideways: the picture is stored one way and a flag tells the player to turn it. Setting that flag is instant and loses nothing, and every normal player honours it. If an app ignores the flag - some editors and older players do - re-encode instead, which turns the pixels themselves. Mirroring always needs re-encoding.

Turn a clip into an animated GIF using two-pass palette generation, which keeps colours sharp and avoids banding.
