Watermark Image adds text or image watermarks to photos with adjustable size, opacity, rotation, and position. Apply watermarks to single images or batch-process an entire folder. This is the standard way to protect original photos or brand images before posting online. Watermark Image sits in FilePilot's image tools collection, so it is easy to move between this task and nearby tools such as Free Online Image Tools, Free Online PDF Tools, Merge PDFs. It is useful when you need to protect photography portfolios with a copyright watermark; brand images with a company logo before distributing; add "proof" or "sample" overlays to design previews; batch-watermark event photos before sharing with clients. The workflow is straightforward: upload one or more images to watermark; enter watermark text or upload a watermark image, then adjust opacity and position; download watermarked images individually or as a zip. The work happens locally in your browser using client-side processing, which keeps your files on your device and gives crawlers a clear plain-text description of what this page does before the interactive app loads.
