Image Orientation & Dimension Rules
Understand how angle rotations adjust viewport bounds, coordinate matrices, and color profiles.
Automatic Dimension Swapping
When rotating 90° clockwise or counter-clockwise, width and height values swap automatically (e.g. 1920×1080 becomes 1080×1920) without visual clipping.
Alpha Transparency Preservation
Rotated PNG and WebP files preserve 8-bit alpha channels. Transparent backgrounds remain fully transparent without unwanted solid borders.
Hardware Accelerated Canvas
Rotations use GPU-accelerated 2D context affine transformations inside your web browser, ensuring high performance with zero network transfer.
