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.

Most tools only show where an image appears. Sealby identifies the buyer and order behind a leak. That distinction matters when the same artwork is delivered to many buyers.

We keep the workflow short: store one original, seal per buyer before delivery, and keep a delivery record you can match later. The sealed file remains a finished PNG—not a visible watermark that is easy 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.
