Your document stays in your browser

PDF Master Editor processes the PDF and image files you choose on your device using browser JavaScript. The application does not send those documents, drawn signatures or document text to a file-processing server.

What is saved?

Your open document, added objects and Undo/Redo history are held in browser memory for the current session. Download PDF writes a new file using your browser's download controls. The application does not overwrite your source file.

What happens when I close the page?

Session edits are not automatically saved to an account or cloud database. Download the edited copy before refreshing or closing the page. A drawn signature is retained only in the current page session.

Website requests

Loading the website requests its application files from the hosting service. The hosting service may handle ordinary connection metadata, such as your IP address and request time, according to its own policies. The editor itself does not include advertising, analytics trackers or a document-upload endpoint.

Shared devices

Downloaded PDFs remain wherever your browser saves them. Take normal care with files on shared devices, especially documents containing private information. This web version does not provide encrypted cloud storage or certificate-based signing.
