Perguntas frequentes

Is this a legally binding signature?

QuietPDF provides basic e-signing. For legally binding signatures, consider qualified electronic signatures.

What signature formats are supported?

You can draw your signature with a mouse or touchscreen, type your name in a signature font, or upload an image of your handwritten signature.

Is my signature image stored by the tool?

No. Your signature is embedded directly into the PDF file only. QuietPDF does not store or share your signature data.

Can I sign on mobile devices?

Yes. The signing tool works on mobile browsers. You can draw your signature directly on your phone or tablet screen.

Should I sign before or after compressing?

Sign after finalizing the document structure and immediately before delivery. Compressing or modifying pages after signing may invalidate the signature appearance.
