System FAQ

How do I sign a PDF online for free?

Create your signature by drawing or typing it, upload the PDF you need to sign, choose the page, then drag your signature to the right spot and resize it. Click 'Sign & Download' to get the finished PDF. Everything happens locally in your browser.

Is it legal to sign documents this way?

In many countries, a typed or drawn electronic signature is legally valid for common agreements (this varies by jurisdiction and document type). For high-stakes legal documents, check your local e-signature laws and whether a certified/qualified signature is required.

Are my documents uploaded to a server?

No. The signature canvas and PDF signing both run entirely in your browser using local processing. Your signature and document are never uploaded, stored, or transmitted anywhere.

Can I use my signature elsewhere?

Yes. Export your signature as a transparent PNG and reuse it in other apps, email signatures, contracts, or image editors.
