Drop a PDF here to add a watermark.
Add a custom text or image watermark to every page — or just odd, even, or selected pages. Fine-tune the position, opacity, color and size with a live preview before you export. Everything runs in your browser with pdf-lib, so the output preserves the original vector quality and your PDF never leaves your device.
