Common Questions

Frequently Asked Questions

Everything you need to know about legally signing PDFs, privacy protection, and document flattening.

Are electronic signatures legally binding on contracts and leases?

Yes. Under the United States Electronic Signatures in Global and National Commerce Act (E-SIGN Act), the Uniform Electronic Transactions Act (UETA), and the European Union eIDAS regulation, electronic signatures carry the same legal weight as traditional wet-ink signatures for commercial contracts, employment agreements, non-disclosure agreements (NDAs), and residential leases.

What does "Flatten PDF" mean when signing?

When a signature is flattened, it is permanently merged into the underlying page graphics stream. Without flattening, a signature exists as a floating annotation layer that subsequent recipients could easily click, move, resize, or delete in other PDF viewers. Flattening ensures tamper-resistant finality.

Is my saved signature transmitted to any cloud servers?

Never. Your signature drawings and initials are stored strictly in your browser's local HTML5 localStorage on your personal device. No server ever sees, stores, or receives your signature image.

Can I place my signature on the last page and initials on every page?

Yes! You can jump to the last page using the 'Last page' shortcut button to place your primary signature and date stamp, and use the 'All pages' button to stamp your initials across every page in the agreement simultaneously.
