Page Pruner: hide what you don’t need

Want to clear clutter from a webpage? Drag Page Pruner to your bookmarks bar.

Click the bookmark on any page. A floating panel lets you choose Delete element or Keep element and delete the rest. Hover to highlight an element, then click to apply your choice. Use Undo to reverse a click, or Done to close the panel. You can also press U or Esc.

The changes only affect your current view. Reload the page to restore it. The bookmarklet is self-contained and loads no external scripts.
