NullClipper

NullClipper is a simple snipping tool for the page you are looking at.

Click the toolbar icon or press Alt+Shift+X. Choose Snip or GIF, then drag a region (or capture the whole tab). The image is copied so you can paste it with Ctrl+V.

Optional: turn on NullImage in the popup to upload an encrypted snip and copy a private share link. You can set expiry, burn after first view, and a password.

This extension only captures the current tab, not your whole desktop or other windows. Pages like opera:// cannot be captured.
