Transform any webpage into an editable canvas with Web Screen Draft.
Web Screen Draft is a powerful yet privacy-first tool for legal professionals, product teams, compliance officers, and anyone who needs to modify web content visually and capture the results. Whether you're documenting evidence, creating mockups, or preparing compliance reports, Web Screen Draft makes it effortless.
VISUAL PAGE EDITING Select any element on a webpage and drag it to a new position. Switch to text mode to select specific words or phrases and turn them into movable overlays. Double-click any text to edit its content inline. All changes stay in place until you reload the page or click Reset.
DRAWING & ANNOTATION TOOLS A built-in floating toolbar gives you access to a full set of annotation tools: • Selection tool — select, move, and manipulate page elements • Rectangle & Circle — draw shapes to highlight or redact areas • Arrow & Line — point out specific elements or draw connections • Freehand draw — sketch directly on the page • Text box — add custom text annotations anywhere • Eraser — remove any annotation or pasted element • Type inside shapes — double-click a rectangle or circle to add text inside it
The toolbar is draggable, so you can reposition it anywhere on the page to stay out of your way.
RESIZE & ROTATE Select any element, pasted image, or drawn shape to reveal 8 resize handles — drag corners for proportional scaling, edges for free scaling. A rotate handle above the selection lets you rotate any element to the exact angle you need.
