Arrows are essential annotation tools for pointing out specific content, creating callouts, or directing attention to important sections. Here's how to add arrows to a PDF in your browser.
Go to pdfeditor.onl/pdf-studio and upload your PDF.
Select the Annotation / Pen tool. Choose a color (red is most visible) and an appropriate stroke width. Draw an arrow shape — a straight line ending in a small V or triangle for the arrowhead.
Tip: For a clean straight arrow: draw the shaft line first as one stroke, then add the arrowhead as two short diagonal lines at the endpoint. Zoom in to 150% for more precise control.
If you need to adjust the arrow's position, use the Undo button and redraw. Annotations can be repositioned immediately after drawing before confirming.
