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 RubberStamps.com?

PDF Verified vs RubberStamps.com

A digital alternative to a physical stamp from RubberStamps.com. Design the same daters, notary, address or custom-logo stamps and use them on your PDFs in seconds, with QR verification built in.

Design your company stamp or seal now. Round seals, dated stamps and approval marks, with a date that fills itself in and a serial number that never repeats. Free to design, and it goes straight onto a PDF, a Word file or an Excel sheet.

Broad custom rubber-stamp retailer with a large catalog, daters, notary, address, inspection and logo stamps, all manufactured and shipped as physical ink stamps.

PDF Verified vs RubberStamps.com in depth

RubberStamps.com stands out for the breadth of its catalog, daters, notary, address, inspection and custom-logo stamps, all as physical products. If your work is inherently paper-based, that range is a genuine advantage and worth the order. The limitation is simply the medium: every one of those stamps marks paper, and none of them can be applied to a digital document or verified after the fact.

PDF Verified covers the same categories as digital stamps. A dater becomes an auto-updating date stamp, a notary or address block becomes a reusable seal, and each can be serialized so a recipient can confirm it. You get the variety without the shipping wait, and you can still export a PNG if you decide you want the physical version too.

Why teams choose PDF Verified over RubberStamps.com

Recreate any RubberStamps.com style, dater, notary, address or logo, as a digital stamp.
Use it on PDFs and Word documents instantly, not just printed paper.
Serialized, QR-verifiable seals so a stamp can be checked as genuine.
Edit the wording or date and stamp again for free instead of ordering a replacement.
Need a physical stamp too? Export a transparent PNG of your design for any manufacturer.

Is RubberStamps.com better than PDF Verified?

RubberStamps.com has a wide catalog of physical ink stamps and is a fine choice when you truly need one for paper. If your documents are digital, PDF Verified lets you design the same kinds of stamps and apply them to a PDF in seconds, with public QR verification and an audit trail, at a fraction of the cost and with nothing to ship.

A RubberStamps.com alternative that does not need posting

If you searched for a RubberStamps.com alternative, the thing you are weighing is whether the stamp has to be a physical object. RubberStamps.com makes a good one, and a good one takes days to arrive and then has to be near you and near a printer. PDF Verified makes the same mark digitally: design the seal, drop it on a PDF, a Word file or an Excel sheet, and the document is stamped and sent in the time it takes to read this. There is no shipping, no re-order when the ink dries out, and every stamped page carries a QR code anyone can scan to check the document is the one that was stamped.

Where a rubber stamp still wins: paper you have to physically mark, and offices that want the ritual of it. Where this wins: everything already living as a file, which for most businesses is now everything.

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.
