Three ways to add your signature
PDFArena gives you three ways to sign. Draw a handwritten signature with your mouse, trackpad, or finger for the most natural look. Type your name and pick a signature-style font. Or upload a photo or scan of your real signature and place it on the document.
However you create it, you drag the signature to the exact spot, resize it to fit, and download. The signature is permanently embedded in the PDF, so it displays correctly in any viewer — no special software needed to open it.
Private by design
Adding a signature to a PDF often means handling a sensitive document. PDFArena keeps it private: the PDF is opened and signed entirely in your browser and is never uploaded to any server.

FAQ
Common questions
How do I add a signature to a PDF?
Open the PDF in PDFArena, click Add Signature, then draw, type, or upload your signature. Click the page to place it, drag to position, and download the signed PDF.
Can I add an image of my signature to a PDF?
Yes. Upload a PNG or JPG of your signature and PDFArena will place it on the page. A transparent PNG looks cleanest over the document.
Will the signature stay in the PDF permanently?
Yes. The signature is flattened into the downloaded PDF so it appears correctly in every PDF reader and cannot be moved by the recipient.
Is adding a signature to a PDF free?
Completely free — no account, no watermark, and no limit on how many PDFs you sign.
