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 SignWell?

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

PDF Verified vs SignWell in depth

SignWell (formerly Docsketch) is one of the better-designed budget signing tools, with a friendly free tier and clear pricing that make it popular with freelancers and small teams. For simple, low-volume signing it is genuinely pleasant to use. Its scope is intentionally narrow, though: it does the signature and the audit log, and stops there.

PDF Verified covers that same easy signing and then extends it where SignWell does not go, public QR verification anyone can scan, serialized company seals and approval stamps, and optional KYC identity verification before a signer proceeds. Pricing is per document or a flat plan instead of per user, so if your signing is occasional you are not carrying a monthly seat between the documents that actually matter.

Why teams choose PDF Verified over SignWell

PDF Verified covers signing plus verification plus stamp/seal workflows in one product.
Pay-as-you-go lets occasional users sign for $1.50 without starting a monthly plan.
Every completed PDF gets public QR verification so recipients can confirm authenticity without logging in.
Serialized company seals and approval stamps add a fraud-prevention layer SignWell does not focus on.
Free document verification and SHA-256 authenticity checking create a stronger recipient trust path.

Is SignWell better than PDF Verified?

SignWell is a good lightweight eSignature product for simple signing and audit reports. PDF Verified is built for teams that also need public QR document verification, serialized company stamps and seals, PDF authenticity checks, and pay-as-you-go signing without starting a subscription.

Looking for a SignWell alternative?

That search almost always means one of two things: SignWell costs more than the signing you actually do, or the way in is heavier than the job. SignWell starts at $12 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 SignWell 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. Sign one thing, send it, look at the audit certificate, and decide after that.

How much does SignWell cost per user?

Published pricing starts around $12 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 2026-06.

What PDF Verified is, and what it is not

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.
