Image Rotator & Flipper

Image rotation changes the orientation of an image by turning it 90, 180, or 270 degrees, or by any arbitrary angle. The most common need for rotation comes from smartphone cameras. When you take a photo holding your phone vertically or at an angle, the camera sensor captures the image in its native landscape orientation and stores the actual orientation as EXIF metadata. Most modern software reads this EXIF orientation tag and displays the image correctly, but some applications ignore it — causing photos to appear sideways or upside down. Rotating the image permanently applies the correct orientation to the pixel data itself, eliminating dependence on EXIF metadata for proper display. The Canvas API used by this tool creates a new canvas at the rotated dimensions, applies the rotation transformation, and draws the image in its new orientation. For 90-degree rotations, width and height swap. For arbitrary angles, the canvas must be enlarged to contain the rotated image without clipping corners.

Photo rotation needs arise in several common scenarios. Fixing sideways phone photos is the most frequent — when a photo appears rotated in an email, on a website, or in a presentation, rotating it permanently corrects the display across all platforms. Scanned documents often need rotation when pages are fed at angles or the scanner orientation doesn't match the document. Architectural and real estate photography sometimes requires rotation to correct for tilted camera angles. Creative photography uses rotation for artistic effect — tilting horizon lines, creating diagonal compositions, or converting landscape shots to portrait orientation. When preparing images for specific platforms, rotation may be needed to match orientation requirements — Instagram Stories require portrait orientation (9:16), while YouTube thumbnails need landscape (16:9). Batch rotation is useful for photographers processing shoots where the camera orientation changed frequently throughout the session.
