FAQ

Is this a legally binding electronic signature?▾
PDFlys creates an electronic signature (an image of your signature embedded in the PDF). In many jurisdictions, electronic signatures are legally recognized for standard contracts and agreements. For high-assurance use cases like notarized documents, a qualified digital signature with a certificate may be required.
Can I save my signature for future use?▾
Yes. If you have a PDFlys account, your signature is saved securely and can be reused on future documents with one click.
Does my signature get uploaded to a server?▾
No. Signature creation and placement happen entirely in your browser. If you choose to save it to your account, it is stored encrypted in your user profile.
Can I add multiple signatures to one PDF?▾
Yes. You can place your signature on as many pages and locations as needed within the same document.
Can I sign a PDF on my phone?▾
Yes. The signature tool works on mobile devices. Drawing with your finger on a touchscreen is a natural way to create a signature.
