Add freehand drawings and annotations in three simple steps — no software installation required.
Drag and drop your PDF file into the upload area, or click "Choose PDF File" to browse your device. The tool accepts any standard PDF document. Once uploaded, all pages are rendered so you can navigate to the page you want to draw on.
Select a pen color from the palette and adjust the line thickness. Then use your mouse, stylus, or finger to draw directly on the PDF page. Create freehand sketches, circle important sections, draw arrows pointing to key areas, or add any marks you need.
Once you are satisfied with your drawings, click the download button to save the annotated PDF. All drawings are embedded into the document permanently. Your original file is never modified — a new copy is created with all annotations applied.
The easiest way to draw freehand annotations on PDF documents — free, private, and intuitive.
No premium tier, no usage limits, and no hidden fees. Draw on as many PDFs as you need without creating an account or paying a subscription.
Your files never leave your device. All drawing happens locally in your browser. There is no server upload, no cloud storage, and no data collection of any kind.
Draw naturally with your mouse, stylus, or finger. The drawing tool captures smooth strokes for clean annotations, circles, arrows, underlines, checkmarks, and any other marks you need.
Choose any pen color from the full color picker and adjust line thickness to your preference. Use thin lines for precise annotations or thick strokes for bold, visible marks.
Navigate between pages and draw on any page in your PDF. Whether it is a one-page form or a lengthy report, every page is accessible for drawing.
Works beautifully with touchscreen devices and styluses. Draw with your finger on a tablet or use an Apple Pencil or Surface Pen for precise annotations.
