Edit / Annotate PDF online, free and private

Editing a PDF should not require sending a contract, worksheet or private draft to a remote server. This editor places text, highlights, ink, rectangles, ellipses, images and links on a live preview, then writes those edits into a new PDF.

The complete workflow runs locally in your browser. Your source file is not sent to PDFToolz or stored on a server.
