How to Sign a PDF Online Without Printing It

Sign a PDF step by step

1. Open Sign PDF and drop the PDF you need to sign.

3. Place it on the page, resize it, and add it to every page that needs it.
4. Download the signed PDF.

Tips for a clean signature

• On a phone or tablet, drawing with a finger usually looks more natural than with a mouse.
• For an uploaded signature, sign on plain white paper and photograph it in good light, so the background is clean.
• A transparent PNG of your signature sits cleanly over the signature line without a white box around it.

Is a drawn signature legally valid?

Many everyday documents accept a simple electronic signature like this, but rules differ by country and by type of document. Some contracts require a certified digital signature or a handwritten original. Check with the person or organisation that asked for the signature if you are unsure.
