How to Use Drawing Tools on PDFs in Helperbird

PDF drawing is free. Open a PDF and choose Draw to begin.

What are PDF Drawing Tools?

PDF Drawing Tools let you draw directly on any PDF document in Helperbird's PDF Reader. You can use a freehand pen, draw rectangles, ovals, straight lines, and arrows. You can choose from multiple colors, adjust the line thickness, and move or delete individual drawings.

Your drawings stay visible even when you close the drawing toolbar, and you can download the PDF with all your drawings included.

Stroke width: Click the stroke width button to cycle through four sizes: thin (2px), medium (4px), thick (6px), and extra-thick (8px). The button shows the current width so you always know what you're working with.

With your tool and color selected, click and drag on the PDF page to draw.

• For the pen tool, hold down the mouse button and move to draw freehand.
• For shapes, lines, and arrows, click where you want to start, drag to set the size and direction, then release.

Your drawing appears immediately on the page.

Step 8: Close the Toolbar

Click the Draw button again in the main toolbar to close the drawing toolbar.

Your drawings stay visible on the PDF. You can continue reading, navigating pages, or using other Helperbird features. Your marks remain exactly where you placed them.

To make changes, just open the drawing toolbar again.

Step 9: Download Your Marked-Up PDF

When you are finished, click the Download button (the download icon) in the toolbar.

A dialog will appear with two options. Choose With my changes to save the PDF with your drawings. Choosing Original only downloads the PDF without them.

Keyboard Shortcuts

When the drawing canvas is focused, you can use these keyboard shortcuts:

• Tab - Cycle through shapes on the current page to select them
• Arrow keys - Move a selected shape by a small amount
• Shift + Arrow keys - Move a selected shape by a larger amount
• Delete / Backspace - Delete the selected shape
• Escape - Deselect the current shape

Tips

• Use arrows to point reviewers to specific issues in a document.
• Use rectangles or ovals to frame sections that need attention.
• Combine text boxes and drawings for detailed annotations. Add a text box next to an arrow for context.
• Your drawings are saved per page, so each page keeps its own set of marks.
• If you open drawing mode while a text box is being added, drawing mode will close automatically to avoid conflicts.
