How does the Batch Watermark PDFs work?
Apply the same watermark to every page of every PDF in a batch — for marking a stack of drafts as DRAFT, a folder of contracts as CONFIDENTIAL, or a set of internal reports as PROPERTY OF YOUR_COMPANY. Each PDF is processed with the same text, position, font size, and opacity, then bundled into a single .zip with each file suffixed "-watermarked.pdf". Same watermark engine as the single-file Add Watermark tool — diagonal centre is the most visible default.
