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.

How to add a date stamp to a PDF

You can add a date stamp to a PDF online with today’s date filled in automatically, no printer, no manual typing. Design a dated stamp, RECEIVED with a date line, an approval mark, or a simple date, place it on the page, and download the stamped PDF. Designing is free; downloading a stamp is $1.50 pay-as-you-go, or free on any paid plan. Because the date is inserted automatically each time you apply the stamp, a “date received” or “date approved” mark is always accurate.

How to add a date stamp to a PDF — step by step

Design a stamp with a date line — Open the stamp maker and choose a stamp with a date line, a RECEIVED or APPROVED preset, or design your own with any wording. Turn on the automatic date so the current date fills in when you stamp.
Place it on the PDF — Upload your PDF and drag the dated stamp onto the page, over a signature block, letterhead or approval area. Resize it so it sits neatly and reads clearly.
Download the dated PDF — Export the stamped document. Optionally turn on serialization and a public QR link so the dated mark can be verified as genuine and tied to the exact document later.

Today’s date filled in automatically, no manual typing or wrong dates.
Date-only stamps, or RECEIVED / APPROVED / PAID marks with a date line.
Transparent PNG so the stamp sits cleanly over any background.

Free to design; $1.50 to download, or unlimited on a paid plan.

Frequently asked questions

How do I add today’s date to a PDF automatically?

Design a stamp with a date line in the PDF Verified stamp maker and turn on the automatic date. Each time you apply the stamp it inserts the current date, so you never type it in or get it wrong.

Can I set a specific date instead of today?

Yes. You can lock the stamp to a specific date, for backdating a “date received” on paperwork that arrived earlier, or leave it on automatic to use today’s date.

Can the date stamp be verified later?

Turn on serialization and every stamp carries a unique serial and a public QR link, so a dated mark can be confirmed as genuine and tied to the specific document and date.

Will the date stamp have a white box behind it?

No. Stamps export as transparent PNGs cropped to the ink, so a dated stamp sits cleanly over letterhead, forms or coloured backgrounds.
