Send and sign an NDA online, free

Mutual or one-way. Drag a PDF in, add a recipient, send. Both parties sign on their phones in under a minute.

NDAs are the most-signed contract type on the planet. Most platforms make them harder than they need to be, uploads, fields, signatures, three round-trips of email. PDF Verified ships a mutual-NDA template you can fill in, send, and sign in 90 seconds end to end. Legally binding under ESIGN + eIDAS, complete audit trail per signer.

Drop your document here and sign it now. PDF, Word and Excel all work: a .docx or .xlsx is laid out in your browser exactly as it was written, so there is nothing to convert first. Add a signature, a date, a company stamp or a watermark, then download it sealed. Free to start, no account, and the file is never uploaded to open it.

Documents NDAs teams sign

How PDF Verified fits

A counterparty who has to download Word, fill in fields, scan a wet signature, and email it back is going to ghost you.

How it works for NDAs teams

  1. Upload the document. Drop in a PDF (or Word/Excel, they convert automatically) and place signature, date, stamp, and initials fields where they belong.
  2. Send or sign on the spot. Email a signing link to each party, or use Quick Sign to sign immediately on any device, no printing, no scanning, no app to install.
  3. Identity when it matters. For high-stakes NDAs paperwork, add email/SMS OTP checks or full ID + selfie verification with liveness detection before anyone can sign.
  4. Every copy is provable. The finished PDF is sealed with a SHA-256 fingerprint, a complete audit trail (who signed, when, from where), and a QR code anyone can scan to confirm the document is genuine and unaltered.

Why it beats print, sign and scan

A scanned signature page proves nothing, the image can be lifted and reused on any document, and there is no way to tell whether the pages around it changed. A sealed PDF Verified document is the opposite: change one character after signing and verification fails. For NDAs teams that answer to auditors, regulators, or opposing counsel, that difference is the whole point.

It is also simply faster. Documents that took days of chasing come back in minutes, reminders go out automatically, and the signed copy files itself on your dashboard instead of a shared-drive folder of "final_v3_signed_SCAN.pdf".

Company stamps for ndas

A signature says a person agreed. A stamp says the organisation did, and in ndas that distinction turns up constantly: on an approval, a certified copy, a receipt, or an invoice an accounts department will not process without the company mark on it. Design a company stamp for ndas once and apply it to a PDF, a Word file or an Excel sheet, on one page or on every page.

The date fills itself in at the moment the stamp is applied, so a batch is never dated wrong, and every impression carries a serial number that does not repeat, which is what makes a stamped ndas document auditable rather than merely marked. Anyone can scan the QR on the result to confirm the document has not changed since.

Design a company stamp or seal free, or put the stamp and the signature on in one pass.

Legal validity

Electronic signatures are legally binding for ordinary business documents in 190+ countries, the ESIGN Act and UETA in the United States, eIDAS in the EU, KICA in Kenya, and equivalents across Africa, Asia, and Latin America. Courts look for intent, identity, and integrity; PDF Verified records all three: a click-to-sign action with timestamps, verified signer identity, and a tamper-evident cryptographic seal.

Frequently asked questions

How does PDF Verified work for NDAs?

NDAs are the most-signed contract type on the planet. Most platforms make them harder than they need to be, uploads, fields, signatures, three round-trips of email. PDF Verified ships a mutual-NDA template you can fill in, send, and sign in 90 seconds end to end. Legally binding under ESIGN + eIDAS, complete audit trail per signer.

Is PDF Verified legally binding for NDAs documents?

Yes. PDF Verified eSignatures comply with the ESIGN Act, UETA, and EU eIDAS, and every signed NDAs document includes a SHA-256 tamper-evident seal, a full audit trail, and a public QR verification page, admissible as evidence in most jurisdictions.

Can I add a company stamp to ndas documents?

Yes. Design a round company seal, an approval mark, a PAID or RECEIVED stamp or a certified true copy stamp, and place it beside the signature or on every page. It works on PDFs and equally on the Word and Excel files ndas teams actually work in, without exporting them first. Whether a stamp is required for a given document is a question for the party asking and for local practice, but where it is expected, providing it is faster than debating it.

What does it cost?

Pay as you go at $1.50 per completed document with no subscription, or take a monthly plan (Personal from $5.60/mo) when volume grows. Building and testing documents is free, you only pay when a signing completes.

What PDF Verified is, and what it is not

Electronic signature law is settled in broad terms and specific in the details. The ESIGN Act, UETA, eIDAS and their equivalents recognise electronic signatures across more than 190 countries, and what decides a particular case is intent to sign plus evidence connecting the signature to the signer, which is what the audit certificate records. Certain document types carry their own formalities wherever you are: deeds, wills, some property instruments, and anything requiring a witness or a notary. Sign only what you are authorised to sign, since applying another person signature without their authority is forgery whatever tool is used.

PDF Verified is a tool for preparing, signing, stamping and checking documents. It is not a law firm, a compliance service or a forensic examiner, and nothing here is legal, financial or compliance advice. Requirements differ by country, by document type and by the party asking, so check what applies to your document before you rely on it, and take advice where the document matters. You are responsible for the documents you create, sign and send, and for having the authority to do so: signing or stamping in somebody else name, or as an organisation you do not represent, is forgery whatever tool is used. To the extent the law allows, we accept no liability for how a document made with this tool is used or relied on. The full position is in our terms of service.
