Authors, market research analysts, and educators sharing pre-release manuscripts, proprietary training modules, or legal contracts need reviewers to read documents without leaking the digital file. Sending standard PDF links allows anyone to download the master file, print physical copies, or forward it to competitors.
In Google Drive: select the PDF file > click Share > click the Settings gear icon at the top right of the share modal > uncheck "Viewers and commenters can see the option to download, print, and copy". When recipients open the link, the browser disables the download button, right-click saving, and text copying, enforcing secure view-only mode.
