Everything you need to share documents and run secure data rooms

Link and document permissions

Control access at every level: per link, per folder, and per document. Granular view and download toggles let you decide exactly who can see and who can download each file. Some links get full access; others see only what you release. Sensitive files stay protected while still easy to share.

Document protection in action

Screenshot protection keeps your documents secure whether viewers try inspect, tab switching, or screen capture.

sendpaper.io/view

Screenshot protection

Documents stay protected when viewers try to use developer tools or right-click inspect. Your confidential data remains secure.

sendpaper.io/view

Screenshot protection

Documents stay protected when viewers open another app or switch tabs to capture the screen. Content remains secure no matter how they try to capture it.

Configure once, protect everywhere

Set up watermark position, rotation, opacity, and tiling in the settings sidebar. Viewers see the watermark applied across every page of your documents.
