Watermarking PDFs is essential for protecting intellectual property or marking drafts. Unlike online tools that upload your file to a server, Toolslove's watermark tool works entirely in your browser using the pdf‑lib library. Your file stays private. You can customise the watermark text, colour, opacity, rotation, and relative font size – and the watermark is applied to every page of the PDF.
