PDF Watermark API

Keep documents secure by adding watermarks to your PDF or Office files through our REST API or by deploying our watermarking library in your self-hosted server. Dynamically add dates, times and pages 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). Easily integrate with code samples available in Java, C#, PHP, JavaScript and .NET Core.
