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 create a professional stamp

Pick a template or shape — Start from one of 200+ industry templates, or choose a shape — circle, oval, rectangle, shield, hexagon, triangle.
Set the size and colour — Adjust the stamp size and ink colour. A standard round seal is about 38mm; rectangles auto-fit your lines.
Add your ring text — Type the text that curves around the outer ring — your company, office or seal name, top and bottom.
Add centre text and dates — Add the centre lines, a date, or a serial. Use {{DATE}} and {{SERIAL}} so they fill in automatically when the stamp is applied.
Drop in a logo or emblem — Upload a logo or add a star, crest or shape element, then move, scale and rotate it into place.
Download or save it — Watch the live preview as you edit, then download the image — or save it to your library to apply to real documents.

Why build your stamp online

Design in your browser. No software, no install, no design skills — on desktop or mobile.
Control of every element. Shape, ring text, centre text, colour, fonts, logos and emblems, each positioned and sized exactly.
Locked serials and QR verification. A saved stamp carries a tamper-evident serial and a code anyone can scan to verify — not just a picture.
Lands at the right size. Every format states the physical size of a real rubber stamp, so it does not arrive page-wide and shove your text around.
Apply straight to documents. Use a saved stamp in Quick Sign or inside an envelope to seal a PDF, then download or send it.

Frequently asked questions

Is the online stamp maker free?

Designing a stamp is free: pick a template, customise the text, shape, colour, logo and size, and watch the live preview. Downloading the image or saving the stamp to your library to apply to documents is where paid features begin.

What file formats can I download?

A high-resolution PNG (transparent, for overlaying on documents, or on a white background), a JPG, an SVG vector for print and design tools, a PDF, and a Word file that floats over your document — or every format at once in a single zip.

Will the stamp keep its size in Word?

Yes. Every image is tagged with the size of a real rubber stamp — 2.2 inches square — so it lands at that size instead of being blown up to the width of the page. The Word version also keeps the date and serial as text you can retype.

Can I add my company logo?

Yes. Upload your own logo as a PNG or SVG, or choose from built-in emblems — bank, government, globe, shield, gear, crown, scales of justice, caduceus and more. Move, scale, rotate and set the opacity of each element.

What shapes and styles are available?

Round and oval seals, rectangles and squares, plus shield, hexagon, octagon and triangle. Round seals support curved ring text and decorative borders: triple ring, double ring, scalloped (notary), gear, burst and rope.

How is a digital stamp different from a photo of a rubber stamp?

A saved stamp can carry a locked serial number and a QR code each time it is applied, so anyone can confirm it is genuine, see which document it belongs to, and check whether it has been revoked. A photographed rubber stamp proves nothing.

Do you support serial numbers and dates?

Yes. Add date and serial placeholders to any line. They are filled in automatically when the stamp is applied to a document, so every impression is unique and traceable — and in the Word download they stay editable text.

Can I use the stamp on a PDF?

Yes. Save the stamp to your library, then upload a PDF in Quick Sign or inside a signing envelope, place the stamp and your signature, and download or send the sealed document.
