Drawing on a PDF — adding a freehand ink stroke, dropping a rectangle over a clause, or signing your name — takes under a minute on any device. This guide covers every method: Mac Preview, Windows Edge, iPhone, iPad, and free online tools.
Frequently Asked Questions
Can I draw on a PDF for free?
Yes. Mac users can use the built-in Preview app at no cost. Windows users have Microsoft Edge. For online drawing without any install, Smallpdf and Xodo both offer free freehand annotation tools. On iPhone, the Files app Markup tool and the [Scanjet app](https://scanjet.app) let you mark up PDFs at no charge.
Why is the draw tool grayed out on my PDF?
The PDF likely has annotation restrictions set by its creator. Try opening it in a different app — Adobe Acrobat, Preview, or a browser — which may ignore those restrictions. If the file is password-protected, you need the owner password to unlock drawing permissions.
Do my drawings save when I close the PDF?
Only if you explicitly save. In Microsoft Edge, press Ctrl+S before closing. In browser tools like Smallpdf, download the annotated file after editing — do not just close the tab. Preview on Mac auto-saves to the original file unless you duplicate it first.
Can I draw on a PDF on my iPhone?
Yes. Open the PDF in the Files app, tap the share icon, and choose Markup. Use your finger to draw, add shapes, or write a signature. For professional-quality markup with more tools, the [Scanjet app](https://scanjet.app) includes a full annotation layer on top of scanned and imported PDFs.
Is drawing on a PDF the same as editing it?
No. Drawing (annotation) adds a non-destructive layer on top of the existing content — the original PDF text and layout are untouched. Editing changes the actual text or structure of the document. Most PDF tools support annotation; full text editing requires a dedicated PDF editor like Adobe Acrobat Pro.
