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.

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.

Electronic signatures for law firms and legal teams

NDAs, retainers, settlements, engagement letters, signed and audit-trail-stamped without a printer.

Law firms can't afford to send a client a Word file and hope they print, sign, scan, and email it back, and they can't afford to have a settlement, power of attorney, or engagement letter signed by an impostor. Fraudsters impersonate lawyers, clients, and even opposing counsel to forge legal documents. PDF Verified pairs cryptographically-signed PDFs with a KYC + liveness identity check, so you can prove the signer is who they claim to be, backed by full audit trails (timestamps, IP, hash chain) that hold up in court under ESIGN, eIDAS, and UETA.

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.

Who this is for

This is the page for an eSignature for law firms, and equally an eSignature for solicitors, an eSignature for paralegals and an eSignature for in-house counsel. Same tool, same price, same absence of a seat to buy: sign a document, pay $1.50 if you want to download it, and go. Everything below is the longer version.

People in legal / law firms search for this in their own words: compliant digital contract signing, eIDAS compliant signatures and digital contract execution for law firms. It is one tool underneath, and the paperwork is what differs.

Documents Legal / Law firms teams sign

Engagement letter / retainer agreement
Power of attorney
Settlement agreement
Affidavit / sworn declaration
Mutual NDA
Statement of work / fee letter

How PDF Verified fits

KYC / ID + liveness check binds the signature to a verified person, stops impostors posing as a lawyer, client, or counterparty.
Public QR verification lets any court, registry, or opposing firm confirm a document (and who signed it) is genuine and unaltered.
Sequential routing enforces the proper signing order, counsel before client, mutual NDAs in lockstep.
Per-signer access code (OTP via email or SMS) gates the document before opening.
Cryptographic SHA-256 fingerprint + signer hash chain on every audit cert, court-admissible.

The nightmare isn't a slow signature, it's a forged one from someone impersonating your client or counsel. Identity-verified signing removes the doubt.

How it works for Legal / Law firms teams

Upload the document. Drop in a PDF (or Word/Excel, they convert automatically) and place signature, date, stamp, and initials fields where they belong.
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.
Identity when it matters. For high-stakes Legal / Law firms paperwork, add email/SMS OTP checks or full ID + selfie verification with liveness detection before anyone can sign.
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 Legal / Law firms 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 legal / law firms

A signature says a person agreed. A stamp says the organisation did, and in legal / law firms 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 legal / law firms 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 legal / law firms 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

Can a board resolution be signed electronically?

A board resolution electronic signature, sometimes called a board resolution digital signature, is ordinarily valid, and written resolutions signed in counterpart are exactly the case electronic signing suits: each director signs their own copy, at their own time, and the record shows who signed and when. What to check first is the company's own articles, because a constitution can impose formalities the general law does not, and some registries still want a wet signature on filings.

How do we handle master services agreement e-signing across two companies?

Sequential routing, so an MSA goes to your signatory first and the counterparty's second, with each schedule and annex attached to the same envelope rather than emailed separately. Both sides get the same sealed file and the same verification link, which removes the argument about whose version is the executed one.

Where can I sign an NDA online free?

Signing is free here and a completed download is $1.50, which for a mutual NDA is usually the whole cost of the transaction. Bilateral NDAs sign in lockstep: both parties on the same document, both recorded, one sealed file at the end rather than two half-signed ones.

Is an electronic signature enough for a deed or an affidavit?

Frequently not, and this is the place to be careful rather than reassuring. Deeds, wills, affidavits and anything requiring a witness or a notary carry formalities that vary by jurisdiction and that electronic signing does not remove. For ordinary commercial contracts the ESIGN Act, UETA and eIDAS are clear. For the formal categories, check the local rule before you send it.

How does PDF Verified work for Legal / Law firms?

Is PDF Verified legally binding for Legal / Law firms documents?

Yes. PDF Verified eSignatures comply with the ESIGN Act, UETA, and EU eIDAS, and every signed Legal / Law firms 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 legal / law firms 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 legal / law firms 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.
