Watermark PDF
Add text or image watermarks to any PDF. Free, no sign-up, 100% private.
Free Watermark PDF - Watermark PDFs Online is a free online tool that stamps a text or image watermark on every page of your PDF document. Customize the watermark text, font size, color, opacity, rotation angle, and position — place it diagonally across the center, along the top or bottom, or in any corner. You can also upload a logo or image as a watermark for branding purposes. The tool supports tiled watermarks that repeat across every page, single-position watermarks, and layered placement over or behind the existing content. All processing happens locally in your browser — your PDF is never uploaded to any server. There is no file size limit, no sign-up, and no additional watermark added by the tool itself. It is ideal for marking documents as "Draft," "Confidential," or "Sample," adding copyright notices, branding company reports with logos, stamping receipts with approval status, or protecting intellectual property before sharing documents externally. Works on Windows, Mac, Linux, iOS, and Android.
