Hypothesis uses the PDF.js viewer, which is the same PDF viewer used in Firefox. This viewer contains controls that allow you to rotate the PDF. We’ve noticed that some users accidentally rotate the PDF while annotating. To fix this, simply press the ‘r’ key on your keyboard. This hotkey rotates PDFs in the viewer and will bring your PDF upright again.
