How to add a draft or logo watermark to a PDF

QUICK ANSWER

Open the PDF and choose the watermark type. Start with one page so you can judge how the mark sits over real content. Select all, odd, even or specific pages, then use Add watermark.

A light “DRAFT” label can make a review copy easier to recognize. Watermark PDF adds a new text or image mark to chosen pages and lets you control its position, angle and opacity.

1. Open your file

Open the PDF and choose the watermark type. Start with one page so you can judge how the mark sits over real content.

2. Work through the settings

  1. Enter the text, or choose the watermark image. For text, prepare the preview so the mark is visible on the page.
  2. Set the size, color, angle and opacity. A faint mark is usually easier to read through than a fully opaque one.
  3. Choose a single placement or repeat the watermark across the page.
  4. Select all, odd, even or specific pages, then use Add watermark.

3. Check before you share

  • Read small text underneath the mark.
  • Check that the chosen pages received the watermark and other pages did not.
  • Open the downloaded PDF before sharing it as a review copy.

File limits and first-use notes

The file budget is 350 MB, with up to 150 pages per source PDF. Adds a new watermark; it does not remove an existing one. Text watermarks use a rendered image for consistent font appearance.

Questions you may have

Can I watermark only the first page?

Yes. Use the page selection and enter the first page rather than applying the mark to the whole document.

Can I change the watermark after saving?

Keep the original clean PDF and create another watermarked copy with the new settings. Do not rely on being able to remove every saved mark later.
