Stamp any page of a PDF: auto-remove the white background, adjust size, opacity, rotation and position, or apply a seam stamp.

How to use: After uploading a PDF, choose a seal image (PNG / JPG). In the crop dialog you can select the seal area, auto-trim the edges and remove the white background or black text so the seal sits cleanly on the page.; For a single stamp you can set size, opacity, rotation and a 3×3 position, or drag it directly on the preview. It is applied to every page by default; you can also start from a given page or list specific pages.; A seam stamp splits the seal evenly across the page edges of several pages and restarts every N pages (Cycle pages) — ideal for contracts.
