Guides

Short guides on marking your photos, ID copies and documents before you share them, and on finding out whose copy turned up somewhere.

• How to watermark your ID before you send a copy
  Give every landlord, bank or employer their own copy of your ID, with an invisible mark. A free check shows whose copy it was.
• How to find out who shared your photo
  Give each person their own invisibly marked copy of your photo. The mark stays through screenshots, and a free check tells you whose copy it was.
• Visible or invisible watermark: why invisible wins
  A visible watermark spoils the picture and can be cropped off or erased by AI in seconds. An invisible one stays in every copy, and a free check finds it.
• How creators can trace where their photos end up
  Mark every photo you send to a brand, an agency or a client with an invisible note. If it's reposted, a free check shows your mark.
