To whom it may concern,
Kind regards,
What would you like to do?
From your file to a checkable record
Upload your document
Add a PDF or Word file. Word files are converted to PDF for you.
Place your marks
Add an authorised stamp, your signature or initials, and any text such as a date.
Review and issue
Check every page, choose whether to add verification and a QR code, then finish.
Share and verify
Download the PDF and send it. Recipients can scan the QR code and compare their copy.
Give recipients a way to check
A stamp and signature show your marks. A verification link ties the document someone received back to the record you issued.
Recipients scan the QR code, see the record status, and can upload their copy to see whether it exactly matches the issued file. No sign-in. The file they upload is never stored.

Common questions
Can I use my existing stamp and signature?
Yes. Upload an image of your stamp, signature or initials. Light paper backgrounds are removed automatically. You can also design a stamp in the Stamp Maker.
Can my team use Metax Seal?
Yes, on Standard and Premium. Team members join by invitation. Administrators choose which stamps are shared; signatures always stay private.
Is this a certificate-based digital signature?
Partly. Every issued PDF is digitally signed with a certificate issued by the Metax Seal certificate authority, so any change after issue is detected by PDF readers. Because that authority is our own, readers show the signer as unverified until you install our certificate (see the Trust page). It is not a government-licensed or qualified electronic signature. If a regulator or counterparty requires one, use a qualified provider for that step.
Can I collect signatures from other people?
Yes, on all plans (Free allows 2 signers per request). You mark where each person signs, they get a link, confirm their email with a one-time code, and sign on any device. When everyone has signed, you get the final PDF with a certificate of completion listing who signed, when, and from where.
What does an exact match mean?
The PDF someone uploads has the same SHA-256 fingerprint as the file you issued, so it is identical byte for byte. A re-saved, edited, printed or compressed copy will not match even if it looks the same.
Do recipients need an account to verify?
No. Anyone with the QR code, the record code or the file itself can open the verification page.
Are my uploaded documents shared?
No. Your documents are visible only to you and your organisation. A public verification page shows the record status, issuer and issue date, and the document title unless you hide it. It never shows the document itself.
Stamp. Sign. Share with confidence.
Prepare your next document in one workspace, then give recipients a way to check the issued record.
