Frequently Asked Questions

Can I use a logo image as a watermark, not just text?

Yes. You can type a text watermark up to 200 characters, or upload an image such as a logo to use instead.

Can I rotate the watermark?

Yes, you can place it flat at 0 degrees or angled diagonally at 45 degrees.

Can I control how transparent the watermark is?

Yes. You can set the opacity from fully solid to nearly invisible, so it doesn't obscure the content underneath.

What does tiling do?

Turning on tiling repeats the watermark across the whole page instead of placing it once, which makes it harder to crop out.

Can I watermark multiple PDFs at once?

Yes. Upload several files and each one is watermarked and returned together in a single zip download.

Does the watermark remove or replace the original content?

No. The watermark is layered on top of each page. The original content remains underneath it.

Is it safe to upload confidential documents?

Yes. All uploads happen over an encrypted connection, and both the source file and the watermarked PDF are automatically deleted from our servers after processing.

Is watermarking a PDF really free?

Yes. There is no cost, no subscription, and no account required.
