Rotate Video 90 Degrees
A video filmed with the phone turned the wrong way plays sideways. Rotate it a quarter turn right or left and the fix is written into the picture, so it stays upright everywhere.

Why use Aback Video for this
Every orientation
Rotate by 90, 180 or 270 degrees and mirror horizontally or vertically, in any combination.
Live preview
The player shows the new orientation before you process anything.
Fixed for good
The rotation is applied to the pixels, so every app shows it the right way up, not just players that read rotation tags.
Never uploaded
The video is rotated in your browser and stays on your device.
Frequently asked questions
Why does my video play sideways on some devices only?
Phones often store rotation as a hidden flag that some players ignore. Rotating here turns the actual frames, so every player shows it the same way.
Which way should I rotate?
Pick 90 right if the top of the picture currently points left, and 90 left if it points right. The preview shows the result before you process.
Why is my phone video sideways on some apps but not others?
Phones often save a rotation tag instead of rotating the pixels. Some apps read the tag, some ignore it. Rotating here writes the turn into the picture itself, so it looks right everywhere.
Will I lose quality?
Rotating requires a re-encode. With the default Higher quality setting the difference is very hard to see.
How do I mirror a selfie video?
Set Rotate to 0 and Flip to Mirror. Text that appeared backwards will read correctly.
Is my video uploaded?
No. FFmpeg in WebAssembly rotates it on your device.
What size will the rotated video be?
A 90 or 270 degree turn swaps width and height, so a 1920 x 1080 landscape video becomes 1080 x 1920 portrait. The file size stays in the same range.
Can I rotate on my phone?
Yes, in Safari and Chrome. Long videos re-encode more slowly on phones.
