How to draw on a PDF
Last updated: September 6, 2026
Reviewing a document is a physical act: circle the number that looks wrong, strike through the sentence to cut, draw an arrow from the note to the clause it belongs to. Here's how to do that on a PDF, with marks that print properly and never leave your device.
Use our free Draw on PDF tool. It runs in your browser.
Drawing on a PDF, step by step
- Open the Draw on PDF tool.
- Select or drag in your PDF; page 1 renders in your browser so you draw on the real page, not a blank canvas.
- Draw freehand with your mouse, finger or stylus: circles, arrows, crossings-out, initials, margin notes.
- Page through the document with Prev/Next and keep drawing; every stroke is kept per page.
- Press Save drawing and download the annotated PDF.
What freehand is best at
Drawing is the tool for the gestures that typed text cannot make. A circle around a figure that looks wrong says "look here" far faster than a sentence. A line struck through a clause is unambiguous in a way a comment is not. An arrow physically connects a margin note to the exact word it refers to. Initialling a correction, ticking a box, sketching a quick diagram: these are all natural with a pen and awkward with anything else. If your review is mostly these physical marks, this is the right tool; if it is mostly typed remarks, reach for a different one.
Which markup tool for which mark
| Tool | The mark it makes | Reach for it to |
|---|---|---|
| Draw on PDF | Freehand pen strokes | Circle, cross out, arrow, sketch, initial |
| Highlight | Translucent color over text | Flag passages while keeping them readable |
| Add Text | Typed, selectable words | Add a neat label, date or code |
| Sign PDF | A placed, sized signature | Sign an agreement or form |
A productive review often uses two together: highlight the passages you want to discuss, then draw arrows to margin notes where you write the questions with the pen, and send one file with everything visible at once.
How strokes become part of the page
As you draw, the strokes are captured on a canvas over the page preview and then, when you save, burned into the page's own content rather than parked in a separate annotation layer. That distinction is what makes the marks reliable: they display identically in every PDF reader, they print correctly, and no other software can toggle them off or quietly strip them out. The trade-off is that they are permanent once saved, so before you download, Undo last removes your most recent stroke and Clear this page wipes the current page if you want to start that page over.
Real situations it fits
Marking up a contract you have received: circle the figures to renegotiate, strike the clause you want removed, and scrawl "confirm?" in the margin with an arrow to the relevant line. Correcting a proof or design: ring the typo, cross out the wrong word, and point to where the replacement goes. Approving a form: tick the boxes and initial the changes by hand, the way you would on paper, then send the file straight back: no printer, no scanner, no reflowed layout.
Drawn privately, on your own device
Rendering the page, capturing your strokes, and writing the final file all happen in your browser, so a contract or a proof you are marking up is never uploaded to be processed. Nothing about the document travels over the network; only the finished file lands in your downloads. When you are annotating something you would not want a stranger to hold, that local-only design is exactly the reassurance you want, and the how and why are laid out in are online PDF tools safe.
Frequently asked questions
Does the drawing print? Yes. Strokes are burned into the page content, so they appear on paper and in every reader; they are not a hideable annotation.
Can I erase a stroke I regret? Before downloading, Undo last removes the most recent stroke and Clear this page clears the current page. After downloading, rerun the tool on your original file.
Do I need a stylus or drawing tablet? No. A mouse or trackpad handles circles, arrows and crossings-out fine. A stylus just makes handwriting smoother.
Can I draw on more than one page? Yes. Move through with Prev/Next; every stroke is kept per page and written into the download.
Will the marks stay editable later? No. Once saved they are part of the page, which is what makes them tamper-resistant. Keep your original if you expect to redo them.
