Drop a photo, type your watermark text (or upload a logo PNG), and place it. Adjust position, size, opacity, and repeat across the image. Batch-apply to dozens of photos at once.
One photo or a batch. JPG, PNG, WebP, HEIC. Drag a folder to apply the same watermark to everything.
Type text and pick a font/color, or upload a transparent PNG logo. Drag the watermark to position it; adjust opacity, size, and rotation.
Individually or as a zip. Originals stay untouched. Watermark settings save in your browser for next time.
