Rotate & Flip

What this tool does

Rotates an image or GIF in 90-degree steps or flips it horizontally or vertically. Use it to fix a photo taken sideways or to undo a mirror image.

Steps

1. Upload an image or GIF.
2. Rotate with "Left 90°", "Right 90°" or "180°" and flip with "Flip horizontal" or "Flip vertical". The result shows in the preview right away.
3. If you pressed the wrong button, use "Reset transform" to return to the original.
4. Choose the format and quality and press "Download". (A GIF is saved as a GIF)

Settings

• Rotations and flips accumulate in the order you press them. Four turns in the same direction return to the original.
• A 90-degree rotation swaps the width and height.
• Output format: PNG is lossless; JPG and WebP use the quality slider to control file size. For a GIF the format cannot be chosen.

How it works

Rotation and flipping are applied as a coordinate transform (a matrix) when the image is drawn on a canvas. Pixels are only moved, not recalculated, so 90-degree rotations lose no quality. A GIF is first decoded into full composited frames, the same transform is applied to each frame, and it is encoded to a GIF again.

Good to know

• A GIF with many frames or a large size takes time, and a very large one may exceed the memory limit.
• There is no free-angle rotation; only 90-degree steps are supported.
• A GIF does not keep the original loop count and is saved to loop forever.
• JPG does not support transparency, so transparent areas are filled with white.
