Watermarker
A watermark is a logo, signature, or stamp placed over a photo or document to mark it as yours before sharing a preview or proof. Watermarker lets you place one — or a whole grid of them — over a batch of images or every page of a PDF at once.
Everything happens right here in your browser — your files are never uploaded anywhere.

A transparent-background PNG works best. This is your logo or signature — it gets stamped onto everything below.
Drag images or a PDF here, or
Several PNG/JPEG/WEBP images, or one PDF — not both at once.
Drag to move · drag a corner to resize/rotate · Delete removes the selected stamp.
