About Sign PDF
This tool lets you sign PDF documents without printing, scanning or uploading anything. Draw your signature with mouse, touch or stylus, place text anywhere on the page, and optionally stamp page numbers across the whole document — then download the finished file.
It is ideal for signing contracts, approval forms and delivery notes quickly. Because every edit happens locally in your browser, sensitive documents never leave your device.
How to use Sign PDF Documents
- Open your PDF
Drop a PDF file and flip to the page that needs signing with the page selector.
- Add signature or text
Draw your signature on the pad and save it, or type any text. Drag overlays to position them, click to select, and delete what you don't need.
- Apply and download
Optionally enable page numbers, then click Apply & Download. Every page is rebuilt at high resolution with your edits baked in.
Frequently Asked Questions
Is a drawn signature legally valid?
In many jurisdictions a drawn electronic signature is acceptable for everyday agreements, but requirements vary by country and document type. For high-stakes contracts, check local regulations or use a certified e-signature provider.
Can I sign only one page of a multi-page PDF?
Yes. Overlays belong to the page where you place them, so you can sign page 3 of a 20-page contract while every other page stays untouched. Page numbers, if enabled, apply to the whole document.
Are my documents uploaded when I sign them?
Never. The PDF is opened, edited and rebuilt entirely in your browser, so contracts and personal documents stay on your device throughout the process.
