Frequently asked questions

How much does it cost to sign a PDF?+

You only pay when you download: 2.99 per signed PDF, with no subscription and no account. Pro, from 9 per month, includes 25 documents a month and sending documents to other people for signature.

Do I need to create an account?+

No. You can sign and pay for a single PDF without an account. Your document stays in your browser and is never uploaded to any server unless you save it to an account.

Is an electronic signature legally binding?+

Yes. Electronic signatures are legally binding in the US under the ESIGN Act and UETA, and in the EU under eIDAS. They carry the same legal weight as handwritten signatures for most business documents.

Can I sign a PDF on my phone?+

Yes. SignQuick works in any mobile browser (Safari, Chrome). Draw your signature with your finger and download the signed PDF instantly.

How secure is SignQuick?+

SignQuick uses AES-256 end-to-end encryption. Documents are encrypted before leaving your browser. PDFs signed on a Pro or Business account get a SHA-256 tamper-evident seal you can check at signquick.app/verify.
