Rotate Image (90°, 180°, 270°)
Rotate images clockwise by 90, 180, or 270 degrees. Permanently embeds physical orientation into pixel arrays without lossy degradation.
Best solution
Local processing: Rotate Image (90°, 180°, 270°); Exact right-angle orthogonal rotation; embeds physical orientation.

Methodology & calculation rule
90°/270°: Canvas Width ↔ Height Transpose; 180°: Invert both X and Y axes
Quarter turns (90° and 270°) transpose canvas width and height. Eliminates EXIF orientation tag misinterpretations.
All image processing executes client-side within your browser sandbox via HTML5 Canvas and WebAssembly. No photographs, bitmaps, or metadata are ever uploaded to remote servers.
Output files are generated in-memory as local object URLs. Files must be smaller than 20 MB and under 24 megapixels.
Real-World Context & Technical Standards
90°, 180°, and 270° Clockwise Canvas Swaps
Rotating by 90° or 270° transposes the canvas dimensions (width and height exchange places), while a 180° rotation preserves overall canvas dimensions while turning the image completely upside down.
Baking Physical Orientation Into Pixels
Digital cameras frequently rely on EXIF orientation tags (values 1 through 8) that legacy web viewers ignore. Rendering on canvas and re-exporting permanently burns the correct physical pixel orientation into the file.
Lossless Orthogonal Coordinate Mapping
Right-angle rotations do not require fractional pixel interpolation or anti-aliasing resampling, ensuring raster lines and edges remain perfectly sharp without softening.

Frequently Asked Questions
Why did my vertical photo become horizontal?
A 90° or 270° clockwise turn transposes the canvas dimensions so the full rectangular scene fits without clipping.
Will this fix sideways photos on website uploads?
Yes. Rotating burns the orientation permanently into the raster pixels, so platforms that ignore EXIF flags display it correctly.
