Is PDF Verified legally binding?

Yes. PDF Verified signatures comply with the US ESIGN Act, UETA, EU eIDAS regulation, and equivalent eSignature laws in 190+ countries. Every signed document includes a cryptographic SHA-256 fingerprint and a complete audit trail with timestamps and signer hash chain — admissible in court.

How is PDF Verified different from DocuSign?

PDF Verified offers unlimited documents on the $15 Business plan with REST API included. DocuSign charges $40+/user for Business and gates the API behind a $720/month add-on. PDF Verified also includes unique features: public QR verification page on every signed PDF, eStamp designer, AI field auto-detection, and mobile-first signing without requiring an app.

Can I use PDF Verified without a subscription?

Yes. The pay-as-you-go option lets you sign or send one document or envelope for $1.50 without a monthly subscription. Monthly paid plans include a 7-day free trial.

Which file types can I sign with PDF Verified?

Upload PDF, DOCX, TXT, PNG or JPG files. Non-PDF formats are automatically converted to PDF on upload so signers always receive a clean signing-ready document.

How do recipients verify a signed document is authentic?

Every signed PDF includes a QR code on every page. Anyone — even without a PDF Verified account — can scan it to land on a public verification page showing the document status, completion date, SHA-256 fingerprint, and tamper-evidence proof.

Does PDF Verified work on mobile?

Yes — PDF Verified is mobile-first by design. The signing portal uses a native bottom-sheet pattern with touch-optimized canvas signing, sticky CTAs in the thumb zone, and 44px+ touch targets following Apple Human Interface Guidelines. No app download required.

Can I add a company stamp or seal to a document?

Yes. PDF Verified includes a stamp designer for company seals, official seals, approval stamps (APPROVED, PAID, RECEIVED), date stamps, and certified-true-copy marks. Place a stamp on any document like a signature field. On Business plans, the verified stamp library adds auto-incrementing serial numbers, locked metadata, workspace sharing, revocation, and a public QR verification link for every stamp applied.

How do I verify a stamp is genuine?

Each stamp PDF Verified applies mints a unique verification token at /verify-stamp/:token. Scan the stamp's QR code or open the link from the document's audit certificate to see the stamp's name, serial number, the document it was applied to, and whether it has been revoked — so anyone can confirm a company seal or approval stamp is authentic and current.

How do I verify a signature on a PDF is real?

Open the verification page at pdfverified.com/verify and scan the QR code on the signed PDF, paste the verification code, or upload the file. PDF Verified recomputes the document's SHA-256 fingerprint and compares it against the sealed value — if a single byte changed since signing, verification fails. You also see every signer, their timestamps, and the full tamper-evident audit trail. No account is required to verify.

How do I add a digital stamp to a PDF online?

Upload your PDF, open the editor, add a Stamp field, and pick a stamp from your library — a company seal, an APPROVED or PAID approval stamp, a date stamp, or a certified-true-copy mark. The stamp is baked into the sealed PDF with an optional auto-incrementing serial number and a QR code that links to its public verification page. No printer, ink pad, or scanner needed.

eSignature law in United States

Electronic signatures are legally binding under the federal ESIGN Act and state UETA, with the same enforceability as handwritten signatures.

Governing law: ESIGN Act (15 U.S.C. § 7001) + Uniform Electronic Transactions Act (UETA) (2000)

Electronic signatures have full legal validity in the United States under two complementary frameworks. The federal Electronic Signatures in Global and National Commerce Act (ESIGN), enacted in 2000, applies to interstate and foreign commerce. The Uniform Electronic Transactions Act (UETA), adopted in 49 states plus DC, covers intrastate transactions. Together they grant electronic signatures the same legal effect as handwritten ones, with four core requirements: intent to sign, consent to electronic transactions, association of the signature with the record, and accurate record retention. Both laws exclude a narrow class of documents (wills, certain family-law and court orders, utility shutoff notices) where wet-ink is still required.

What makes an eSignature valid in United States

Intent to sign — affirmative action like clicking a "Sign" button
Consent to electronic transactions — disclosed and accepted
Association of signature with record — embedded or cryptographically linked
Accurate record retention — accessible to all parties for the agreed term
Capacity and authority — signer is competent and authorized

Where eSignatures are not valid

Wills, codicils, and testamentary trusts
Certain family-law documents (divorce, adoption decrees)
Court orders, notices, and official court documents
Notices of cancellation of utility services
Product recall notices affecting health or safety
Documents required by law to be notarized (RON laws apply separately)
