How to do

✦

3 quick steps to watermark your PDF.

1

Upload your PDF files

Select up to 12 PDFs to stamp at once, or drag and drop them into the browser. Every file is processed on your device, never uploaded to a server.

2

Choose text or image, then style it

Type a text watermark and set its font size and color, or upload a PNG/JPG logo. Pick one of 9 positions or tile it across the page, then adjust opacity and rotation.

3

Apply and download

Stamp the whole document or a custom page range like "1-3, 5", then download instantly — a single PDF, or a ZIP if you watermarked several at once.
