What is PDF Verified?

PDF Verified (pdfverified.com) is an online platform to sign, stamp and verify PDF documents. You can send a document for legally binding electronic signatures, add a digital rubber stamp or company seal, and let anyone confirm the finished file is authentic and unaltered through a public QR code and SHA-256 audit trail. It is pay-as-you-go with no subscription required, and eIDAS + ESIGN + UETA compliant across 190+ countries.

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.

Can PDF Verified check if a PDF has been edited?

Yes. PDF Verified can recompute the SHA-256 fingerprint of a signed PDF and compare it with the fingerprint sealed at completion. If the file was edited after signing, the fingerprint changes and verification fails.

Does PDF Verified include a certificate of completion?

Yes. Completed documents include an audit certificate, also called a certificate of completion, with signer identities, timestamps, IP records, document fingerprint, verification status, and the event history needed for legal review.

Does PDF Verified include an eSignature API?

Yes. Business plans include a REST API and webhooks for sending documents, embedding signing, applying stamps, checking status, and building automated signing workflows.

Can I create a company chop or official seal online?

Yes. PDF Verified includes editable company seal, company chop, official seal, date stamp, and approval stamp templates. Verified stamps can include serial numbers, locked metadata, revocation, and a public QR verification page.

What is the best DocuSign alternative for stamps, seals, and verification?

PDF Verified is built for teams that need more than basic eSignature: public QR verification, PDF authenticity checks, serialized stamps, company seals, audit certificates, and pay-as-you-go signing from $1.50.

Is there a cheaper alternative to SignNow?

PDF Verified is a lower-cost SignNow alternative: pay-as-you-go from $1.50 per document, or unlimited documents on the $15/mo Business plan with REST API, audit certificates, and public QR verification included — features SignNow gates behind higher tiers or add-ons.

PDF Verified vs SignNow

airSlate's eSign product, strong API but no simple pay-as-you-go entry path.

Developer-friendly API. Used by lots of indie SaaS that need embedded signing.

PDF Verified vs SignNow in depth

SignNow, part of airSlate, competes hard on price against DocuSign and is a reasonable pick for small teams that want templates, roles and a solid API without top-tier costs. It is still, at heart, a per-user subscription: you commit to seats, and the value depends on keeping those seats busy. For occasional or seasonal signing, that commitment is exactly the friction you are trying to avoid.

PDF Verified drops the seat commitment entirely, $1.50 per document or a flat plan, so cost tracks actual usage. On top of the shared legal footing it adds public QR verification, serialized company seals and optional identity verification before signing, which turn a signed file from something you simply store into something a third party can independently confirm.

Why teams choose PDF Verified over SignNow

Embedded signing widget ships in the $15 plan. SignNow's embedded API requires $30/month Premium.
$1.50 pay-as-you-go documents are useful for testing before committing.
Public QR audit URL → anyone scans to verify. SignNow audit trails are PDF-only, no public URL.
No subscription required for one-off documents. Upgrade when monthly volume becomes regular.
AI field detection included on Business, SignNow charges separately for "AI Forms".
