Technical Overview & Architecture
Rearrange and organize PDF document pages visually. Rotate upside-down or sideways pages (90°, 180°, 270°), shift page order with arrow controls, and delete unwanted blank or draft pages before saving your finalized PDF document.
Page thumbnails are generated locally via pdfjs-dist. Rotation modifications adjust the page dictionary /Rotate attribute in pdf-lib, ensuring instantaneous, mathematically lossless rotation without recompressing page contents.
