FAQ

Certifying your artwork, explained

Why do I need to certify my artwork?

A certificate gives each work a clear record of authorship, artwork details, provenance, and verification. It makes the piece easier to share, sell, insure, and trust after it leaves your studio. It also gives collectors the option to see your new artworks.

Is proofmark.art free to use?

Yes, proofmark.art is free to use. After you create an account, you will have access to:

  • Unlimited artwork registration.
  • Unlimited certificate generation for your artworks, with a shareable certificate link and a printable certificate template.
  • A public portfolio page where collectors can view your artworks.
  • Visit tracking for your certificates, artwork pages, and portfolio.
Do I need to buy a proofmark.art tag?

No. The proofmark.art tag is optional.

You can create certificates, share certificate links, print certificates, and manage your portfolio without buying a tag. The tag is simply a physical NFC sticker that lets collectors tap the artwork and open its digital certificate.

What is a proofmark.art tag?

A proofmark.art tag is an NFC sticker that can be attached to the physical artwork and linked to its certificate of authenticity.

When someone taps the tag with their phone, they can open the artwork's digital certificate and view its details.

Is my data secure?

We use encrypted connections, secure authentication, signed upload links, and infrastructure access controls to protect your account and uploads. No online service can guarantee absolute security.

Artwork images and details you publish on a public profile or certificate are visible by design. You can edit or delete your profile, artworks, and certificates from your account, although issued certificates may remain available for collector verification.

Do I keep the copyright to my artwork?

Yes. You retain all copyright and ownership rights in your artwork and creative content. Uploading an image does not transfer those rights to proofmark.art.

You only give us the limited permission needed to store and display the content, create your certificates, and operate the pages you choose to publish. We do not sell your creative content or use it for advertising or AI model training.

Will my certificate be stored forever?

Proofmark certificates are designed as long-lived public verification pages. Issued certificates may remain accessible for collector verification even if an account changes later. You can export your certificates at any point.

Can someone copy an image or certificate?

Like any image displayed on the web, an image you publish on a public profile or certificate could be saved or copied by a visitor. Account security cannot prevent someone from taking a screenshot of public content.

A copied image or certificate does not give that person your copyright or control of the official Proofmark record. Verification should happen from the proofmark.art URL opened by the NFC tag.

Make every artwork verifiable

Create the certificate, attach a secure proofmark.art tag, and let collectors verify the work with a tap.
