❓ Frequently Asked Questions

What is a PDF watermark?+

A watermark is a text or image overlaid onto PDF pages — typically semi-transparent — to indicate ownership, status (like "DRAFT" or "CONFIDENTIAL"), or to brand documents with your logo.

What image formats can I use as a watermark?+

You can upload PNG, JPG, GIF, or WebP images. PNG with a transparent background is recommended so the watermark blends naturally over your PDF content.

Can I watermark only specific pages?+

Yes! Use the "Apply To" option to stamp all pages, only the first page, the last page, or just odd/even pages — giving you flexible control over watermark placement.

Does watermarking affect the original PDF quality?+

No. The watermark is added as a separate layer on top of (or below) existing content. All original text, images, fonts, and formatting remain completely intact.

Is my file sent to a server?+

No. All processing happens entirely in your browser using JavaScript. Your PDF and any images you upload are never sent to any server and remain completely private.

Can I remove a watermark I added?+

Once a watermark is baked into a PDF it can be difficult to remove, especially with "Over Content" layer. We recommend keeping a copy of the original unwatermarked PDF before applying.

What's the difference between "Over Content" and "Under Content" layers?+

"Over Content" places the watermark on top of the page content — making it more visible and harder to remove. "Under Content" places it behind the text and images, giving a more subtle background stamp effect.
