Upload a PDF, design a text or image watermark, see it live on the page, then stamp it onto the pages you choose.
or drop your file here
Upload the PDF, build a text or image watermark, and adjust its position, opacity and rotation while you watch the live preview. Choose which pages to stamp, then click Apply & download.
Yes. Switch to Image mode to drop in a logo or picture as the watermark. Either way you can set the position, opacity and rotation.
You decide. The watermark goes onto the pages you select, so you can mark the whole document or just specific pages.
No. The watermark is applied right in your browser — your PDF never leaves your device and nothing is sent to a server.
There's no fixed cap. Since everything runs locally, very large PDFs are limited only by your device's memory — on most machines that's plenty.
It's free and there's no sign-up. Just open the page, add your PDF, and download the watermarked file.
