Watermark

Adds a text or image watermark — with batch support.

Overlays a watermark on an image: either text (size, color, stroke) or your own PNG/SVG mark. Position picks from a 3×3 grid plus a “tile” mode (repeating pattern along the diagonal). Opacity, rotation and edge offset are adjustable. Drop multiple files at once for batch mode — the same watermark goes on every image and the results come back as a ZIP. Runs in the browser, files never uploaded.
