Why watermark images
A watermark serves two distinct purposes: attribution and deterrence. Attribution embeds visible information about the creator or rights holder into the image so that anyone who encounters it - on another website, in a shared post, in a presentation - can identify its source. Deterrence discourages casual copying by making the image less immediately usable without the watermark being visible. Neither function requires the watermark to be large or obtrusive. A small, semi-transparent logo positioned in a consistent corner provides both benefits while minimising visual interference with the image itself.
Photographers, designers, illustrators, and product teams working with pre-launch visuals all apply watermarks to images intended for review or low-resolution preview distribution. The watermark communicates that the image is not yet cleared for publication and keeps the association between the work and its creator intact across sharing and repurposing. For text-based copyright notices or captions as an alternative, the add text tool gives you font and position control.
Getting the best result
A PNG watermark with a transparent background blends most naturally over images with varied colours and textures - the transparent areas in the logo allow the underlying image to show through cleanly. An opacity setting of 40 to 60 percent is typically the right balance: visible enough to be clearly present, but light enough not to distract from the image content. Position matters as well: the bottom-right corner is the most common choice because it sits outside the natural centre of attention in most compositions, but if your images frequently have important content in that area, the bottom-left or a corner offset from the primary subject is more appropriate.
