Image Flip & Rotate

What this tool does

Flips an image horizontally or vertically, rotates it by 90° or 180° with one click, or rotates it by any custom angle from -180° to 180° with a choice of transparent or solid-color background for the exposed corners, all directly in your browser.

How It Works

Flip Horizontal mirrors every pixel across the vertical center line, so the pixel at column x swaps with the pixel at column (width - 1 - x) in the same row. Flip Vertical does the same across the horizontal center line, swapping row y with row (height - 1 - y). Rotate 90° and Rotate 180° remap every pixel to a new position using exact integer coordinates, no resampling and no quality loss, and swap the image's width and height for the 90° rotations. The custom-angle slider uses the canvas's native rotation transform to rotate the image around its center by any angle, with the new canvas size calculated from the classic bounding-box formula for a rotated rectangle: newWidth = |W×cos(θ)| + |H×sin(θ)|, newHeight = |W×sin(θ)| + |H×cos(θ)|, so the whole rotated image always fits without being cropped.

Problems it solves

• Fixing a photo taken sideways or upside down from a phone or camera.
• Mirroring a photo so a person or object faces the other direction.
• Straightening a slightly tilted photo, or creating an intentionally angled design element.
