PDF Editor & Annotator

Adds a text note onto any page of a PDF. Runs entirely in your browser — your PDF is never uploaded anywhere.

Lilu Baba's PDF Editor & Annotator overlays new text onto any page at a position you choose, rebuilding the PDF entirely on your device. This adds new text on top of the page rather than editing existing text in place.
