How to rotate a MKV video

  1. 1

    Drop in the video that is facing the wrong way.

  2. 2

    Pick a direction. 90° clockwise fixes most sideways phone footage; mirror and vertical flip cover the odd cases.

  3. 3

    Hit Rotate it and download the corrected video. It is re-encoded once at matching quality, so a single pass looks identical.

Why rotate it here

Real pixels, not a flag

Some tools just flip the rotation flag in the file's metadata, which plenty of players ignore. Flippy re-renders the frames upright, so the video plays correctly everywhere.

Audio copied untouched

Only the picture is re-encoded, once, at matching quality. The soundtrack is stream-copied bit for bit.

Five ways to turn

90 clockwise, 90 counter-clockwise, 180, mirror and vertical flip cover every wrong-way-up video we have ever seen.

No watermark, gone in an hour

Free for everyday use, no signup, and files delete themselves from our servers within an hour.

Why your video was sideways in the first place

Phones do not rotate their sensor when you rotate your hand. They record the same way up regardless and write a rotation flag into the file, trusting players to spin it at playback. Your phone's gallery respects the flag; plenty of browsers, projectors and editing tools do not. Same file, two orientations.

Flippy fixes it at the pixel level: each frame is transposed and the video is re-encoded once at quality matched to the source. After that, no player has to guess.

One rotation pass is visually lossless. Just avoid spinning the same file back and forth repeatedly: every re-encode of a lossy codec shaves a little, so get the direction right and keep that copy.

Questions people ask

Which rotation do I need for phone videos?

Usually 90° clockwise. If it comes out wrong, run it again the other way. It takes seconds and quality holds up fine for a single pass.

Does rotating lose quality?

The video is re-encoded once at matching quality, visually identical for a single rotation. The audio is copied untouched.
