Batch Watermark Tool

Drop in a batch of JPEG, PNG, or WebP photos, set up a text ("PROOF") or your own logo image as a watermark — position, size, color, opacity, even a crop-resistant tiled pattern — watch it update live on a real preview, then download every watermarked photo in one zip. Everything happens in your browser; nothing is uploaded, and there's no per-batch image cap. One-time purchase, works offline forever.
