Watermarking is the practice of overlaying a visible mark — a logo, a name, a copyright notice, or a status label like "DRAFT" — on an image or video. The mark travels with every copy, signaling who owns the asset and whether it is cleared for use.

In a DAM, watermarks are mostly about controlled exposure rather than absolute protection. Common cases: letting clients review a shoot before licensing is settled, sharing pre-release material with press under embargo, or giving wide audiences browsable previews while keeping clean originals behind an approval step. A watermark will not stop a determined bad actor, but it removes the honest mistake — nobody accidentally publishes an image with "NOT FOR RELEASE" across it — and it keeps attribution attached when previews inevitably get screenshotted and forwarded.

The useful property of DAM-applied watermarks is that they are non-destructive. The original file stays untouched; the watermark is applied to renditions served to particular audiences. The same asset can be clean for the brand team, lightly marked for partners, and heavily marked in public search results — one file, several presentations, controlled by policy rather than by exporting marked copies by hand.

In freedam, a watermark designer lets administrators compose watermark layouts — text, logos, placement, opacity — which are then applied to renditions without altering the original asset.
