About watermarking
The watermark is added over the content on every page using pdf-lib. The original page sizes and rotation are retained. The download is named <original filename>-watermarked.pdf. Unlock encrypted PDFs before uploading. Modifying a digitally signed PDF invalidates its signature.
Example: mark a draft document
Enter DRAFT as the watermark text and choose a repeat frequency that keeps the page readable. The watermark is applied at a 45-degree angle on every page. It labels the document but does not prevent copying or editing.
