Draw Directly on Any PDF
Sometimes you need to circle something, draw an arrow to a key detail, or sketch a quick note in the margin. Text boxes aren't always enough.
Helperbird's PDF drawing tools let you draw directly on any PDF - freehand pen, rectangles, ovals, lines, and arrows. Pick your color, adjust the stroke width, and mark up the document however you need.

What You Can Do
Draw freehand: Use the pen tool to draw, underline, or circle anything on the page. Great for quick marks and handwritten notes.
Add shapes: Drop rectangles and ovals to highlight sections, frame important content, or draw attention to specific areas.
Draw lines and arrows: Point to key details with straight lines or arrows. Perfect for calling out specific parts of a document.
Choose your color: Pick from nine colors - red, orange, yellow, green, blue, purple, pink, black, or white - to organize your markup.
Adjust stroke width: Cycle through thin, medium, thick, and extra-thick strokes to get the right look.
Move and delete drawings: Select any shape you've drawn and drag it to a new position. Delete individual shapes when you don't need them anymore.
Undo mistakes: Made a wrong mark? Hit undo to step back, or clear all to start fresh on the current page.

When you close the drawing toolbar, your drawings stay right where you put them. Navigate between pages and your marks are still there.
