Frequently Asked Questions (FAQ)
Is my signed PDF legally valid?
Yes, client-side electronic signatures are recognized under major international frameworks like the ESIGN Act (US) and eIDAS (EU) for standard agreements, invoices, and consent sheets. For complex contracts requiring advanced cryptographic certificates, verified portals are recommended.
Does it flatten or rasterize my PDF pages?
No. Unlike basic editors that convert PDF pages into flat images (which removes text search capability and increases file size), our signer embeds the signature image natively as a new layer. Your text stays selectable and high quality.
Are my private documents sent to any servers?
Never. The file processing, signature mapping, and PDF compile are executed locally in the browser sandbox. No networks are used to process your documents.
