Add text and image watermarks to PDF or Office files through our REST API. Dynamically add dates, times, and page numbers to the header and footer of your documents. Insert lines, rectangles, ellipses, barcodes, RTF files, images, and PDFs into your document. Apply multiple watermarks to the same page or to a range of pages (odd, even, portrait, or landscape). No server setup is required — simply start your free trial or sign up for an account to integrate watermarking capabilities into your application.
