Fonctionnement
How does this tool work?
The drawing is created locally on a transparent canvas using the color and line width you choose. The eraser works before insertion so you can correct the sketch without changing the PDF. Once confirmed, the drawing is cropped and inserted into the shared PDF workspace as a transparent element. You can still move, resize or delete it before creating a new copy of the document.
Use cases
Quick corrections
Circle, underline or point to part of a document to communicate a correction or comment quickly.
Handwritten annotations
Add a note, symbol or small sketch with a mouse, finger or stylus on a touch-enabled screen.
Visual approval
Add a freehand mark to a document without changing its source content or installing desktop software.
