Calling out something on a screenshot or diagram
Drop an arrow on the thing that matters and circle it with an ellipse. Faster than typing out where to look in a long document.

How it works
How it works
Three steps from a plain PDF to a marked-up copy you can hand back.
1
Open your PDF
Drop a single PDF up to 100 MB. Pages render in your browser, so the drawing tools work over scans and image-based PDFs the same as regular ones.
2
Pick a tool and a color
Switch between freehand draw, rectangle, ellipse, and arrow. Pick any color from the swatches or grab a custom one. Move, resize, or delete anything you placed.
3
Download the marked-up PDF
Click Download and your drawings are baked into the page. Anyone opening the file sees them right away, in any PDF reader, on any device.
Use cases
What people use it for
Marking up plans, blueprints, and drawings
Sketch revisions over a floor plan or a wiring diagram, then send the copy back with the changes drawn straight on the page.
Reviewing assignments and homework
Circle answers, draw lines between steps, and add quick notes. The marked-up copy goes back to the student as a single PDF.
Annotating contracts and proposals
Box the clauses that need a second look and draw arrows between linked sections. The other side sees exactly where you want them to focus.

Frequently asked questions
Baked in. When you click Download, every stroke, shape, and arrow is flattened into the page. The file opens correctly in Adobe Reader, Preview, Chrome, Edge, and any other PDF viewer.
