Question 1

What does the Watermark PDF tool do?

Accepted Answer

It overlays text or an image (like a logo) across your PDF's pages, with control over opacity and rotation angle, so you can mark documents as drafts, confidential, or branded before sharing them. The watermark is applied to every page you select.

Question 2

Is my PDF or watermark image uploaded to a server?

Accepted Answer

No, the watermark is applied entirely within your browser, so neither the original PDF nor the image you upload as a watermark leaves your device.

Question 3

Can I adjust how visible the watermark is?

Accepted Answer

Yes, you can control the opacity so it's subtle and doesn't obscure the underlying content, and you can set the angle it's displayed at, such as a diagonal across the page.

Question 4

Does the watermark get permanently applied to the PDF, or can it be removed later?

Accepted Answer

The watermark is baked directly into the page content of the downloaded PDF rather than added as a separate, removable layer, so it becomes a permanent part of that copy of the document.

Question 5

Is watermarking a PDF free, and do I need to sign up?

Accepted Answer

Yes, it's free and no account is needed.
