About Sealby

Sealby is a delivery-marking tool for illustrators and stock creators. Upload one original, then produce a TrustMark-sealed PNG for each buyer. When a file leaks online, upload that image to see which buyer and order it belonged to.

Pixsy tells you where an image appears. Content Credentials tell you who owns it. Sealby tells you which buyer leaked it. That gap matters when you sell the same artwork to many clients.

We keep the workflow short: store one original, seal per buyer before you deliver, and keep a delivery record you can match later. The sealed file still looks like a finished PNG—no visible watermark to crop away.

Who it is for

Freelance illustrators, commission artists, and stock creators who need a practical way to deter leaks and resolve “who shared this?” without rebuilding their whole sales stack.

How it fits your workflow

Seal inside Sealby Studio before you send files by email, Drive, or marketplace download. Tracing stays unlimited on every plan, so investigating a leak does not burn your sealing quota.

TrustMark, not a visible stamp

Sealby embeds an invisible TrustMark (Variant Q). Heavy edits, compression, or cropping can reduce match rates—use the highest-quality leaked copy you can when tracing.
