All rotation matrix modifications execute inside client browser memory. Zero files leave your device.
PDF page orientations are controlled by the /Rotate dictionary key stored within each page object entry. Valid rotation values must be positive multiples of 90 degrees ($0^\circ, 90^\circ, 180^\circ, 270^\circ$).
Using page.setRotation(degrees((currentRotation + angle) % 360)), pdf-lib updates rotation dictionary values directly without re-encoding page content streams.
Because rotation keys instruct PDF viewers to transform display coordinate systems upon rendering, rotating pages is 100% zero-loss and preserves original vector quality and text sharpness.
