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 DocuSign?

PDF Verified is a lower-cost DocuSign 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 DocuSign gates behind higher tiers or add-ons.

PDF Verified vs DocuSign

The enterprise eSignature incumbent, and its pricing reflects it.

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.

Brand recognition + Salesforce integration. The default choice for Fortune 500 procurement.

PDF Verified vs DocuSign in depth

DocuSign is the category benchmark, and for a large enterprise standardising on one signing system across thousands of employees, that maturity is worth paying for. But its pricing is built around per-user plans and envelope limits, which is a poor fit for anyone who signs occasionally or sends in bursts. Pay for a seat you barely touch and the cost per signed document quietly becomes very high.

PDF Verified is designed for the opposite pattern: $1.50 per completed document with no seat to maintain, or a flat plan when volume grows. It matches the legal weight (ESIGN, eIDAS, UETA) and adds things DocuSign either gates behind higher tiers or does not offer at all, public QR verification on every page, serialized company seals, and optional KYC identity checks before signing.

Why teams choose PDF Verified over DocuSign

Unlimited documents on the $15 Business plan vs DocuSign's $40/user Business Pro.
REST API included free with Business, DocuSign charges $720/month as an add-on.
Every signed PDF carries a public QR verification page. Anyone can scan and verify without an account.
Mobile-first signing portal with native bottom-sheet UX. DocuSign's mobile web fights with their app.
Verified stamp library: company seals and approval stamps with auto-incrementing serial numbers and a public /verify-stamp QR link, plus AI field auto-detection, all built-in.

Is DocuSign better than PDF Verified?

DocuSign is the more recognized enterprise brand and integrates deeply with Salesforce. For most SMBs and freelancers, PDF Verified delivers the same legal binding (ESIGN, eIDAS, UETA) at roughly 1/3 the cost, with REST API + QR verification + audit certificates included on every plan rather than gated as add-ons.

Looking for a DocuSign alternative?

That search almost always means one of two things: DocuSign costs more than the signing you actually do, or the way in is heavier than the job. DocuSign starts at $10 a month on Personal, charged per seat, so the bill tracks how many people you have rather than how many documents you send. PDF Verified charges $1.50 for a completed document, or $15 a month for unlimited documents, with no seat to buy and no envelope allowance to run out of. For a business that signs in bursts, a few contracts one month and none the next, that is the whole difference.

If you want a free DocuSign alternative to test with a real document first, you can. Three documents a month are free for as long as you want them, with no card, no trial countdown and no watermark stamped across the result. DocuSign offers 5 (trial only). Sign one thing, send it, look at the audit certificate, and decide after that.

How much does DocuSign cost per user?

Published pricing starts around $10 per user per month on Personal, and the plans people actually end up on are usually higher, because the features that make a signing tool worth having (an API, bulk sending, identity checks, audit certificates) sit further up the list. Check current pricing on their site before you decide, since it moves. The comparison table above is dated 2026-05.

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.
