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.

How to Make a Verifiable Company Seal Online (Not Just a PNG)

Search "company seal online" and you will find plenty of tools that hand you a nice round seal as a PNG. The problem: a picture of a seal proves nothing — it can be copied onto any document in seconds. If your seal is meant to signal authenticity to a bank, registry, partner, or court, you need a seal that can be verified, not just viewed. Here is the difference, and how to make one.

Why a picture of a seal is not enough

A traditional company seal (or "common seal") signals that a document is officially executed by the company. The digital equivalent most generators produce is an image — and an image carries no proof. Anyone who receives a sealed document can lift the seal and reuse it. There is no way for a third party to tell a genuine application from a forged one.

For internal memos that is harmless. For board resolutions, certified copies, share certificates, or anything a regulator might examine, an unverifiable seal is a weak link.

What makes a seal "verifiable"

A verifiable digital seal adds three things a flat image lacks: a serial number unique to each application, a verification token a recipient can check, and a public verification page (often reached by a QR code or link) that confirms the seal is genuine, shows which document it belongs to, and whether it has been revoked.

Crucially, the seal is bound to the document by a cryptographic fingerprint (SHA-256), so if a single character of the document changes after sealing, verification fails. That binding — seal to specific, unaltered document — is what turns a decorative mark into evidence.

Revocation: the thing a rubber stamp can never do

Physical seals and image seals are permanent — once out, they cannot be recalled. A verifiable digital seal can be revoked: if trust changes, or a document is superseded, you withdraw the seal and anyone who verifies it sees that it is no longer valid. That single capability is a strong reason to move company seals online properly, not just as graphics.

How to create one

Open the stamp and seal designer at pdfverified.com/stamp-maker. Choose a round seal, add your company name and registration number around the ring, a centre mark or logo, and a date or serial line. Preview it live, then either download a transparent PNG for $1.50 or apply it directly onto your PDF as a serialized, QR-verifiable seal.

When you apply it to a document inside PDF Verified, the document is sealed with a tamper-evident SHA-256 fingerprint and carries a public verification link on every page — so a recipient can confirm, in seconds and without an account, that the seal and the document are genuine. That is the difference between a seal people look at and a seal people can trust.
