Signing a PDF — answered
Can I sign a PDF for free without signing up?
Yes. Upload your PDF, drop in your signature, and download the signed copy — no account, no payment, no watermark. Create an account only if you want to send a document to other people for signature.
Is signing a PDF online legally binding?
In most cases, yes. The ESIGN Act and UETA in the U.S., and eIDAS in the EU, give electronic signatures the same legal standing as ink for the vast majority of documents. For the strongest evidence, send the PDF for signature so it carries an audit trail and Certificate of Completion.
Will there be a watermark on my signed PDF?
Never. tuyaform is free forever and ad-supported, so your downloaded and sealed documents are always clean — no watermark, no “made with” badge.
Can other people sign the same PDF?
Yes. Add multiple signers, set the order they sign in, and choose how each one verifies their identity. Everyone receives the final sealed copy.
Is my document private?
Your file is encrypted in transit and at rest. If you sign without an account, the document is processed in your session and not shared. See our security page for details.
