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

Yes, both text watermarks (with your choice of wording, font, and color) and image watermarks (using an image you upload, such as a logo) are supported.

Can I control how transparent the watermark is?

Yes, opacity is adjustable so you can make it subtle enough not to obscure the underlying content, or bold enough to be clearly visible, depending on your purpose.

Will the watermark appear on every page, or can I choose specific pages?

By default it applies to every page, which covers the common case of marking a whole document as a draft or confidential — this ensures no page can be separated out without the mark.

Can I rotate the watermark diagonally across the page?

Yes, rotation is adjustable, including the common diagonal placement used for "DRAFT" or "CONFIDENTIAL" style watermarks.

Does adding a watermark affect the underlying text or images?

No, the watermark is layered on top of the existing page content without altering it — the original text remains selectable and the original images remain untouched underneath.

Can a watermark be removed later if I need to update it?

Once applied and downloaded, the watermark becomes part of the page content. If you need to change it, start again from your original unwatermarked file with different settings.

Is my file uploaded to a server?

No. Every operation on this page runs locally in your browser using JavaScript and WebAssembly. Your file is never transmitted anywhere, which also means it works without an internet connection once the page has loaded.

Why watermark PDFs with Tools Root

Marking a document as a draft, confidential, or property of a particular organization is a routine step before sharing it externally, and it shouldn't require design software just to stamp text or a logo across every page.

Full control over placement and appearance

Position, rotation, opacity, and font are all adjustable with a live preview, so you can dial in something subtle in a corner or a bold diagonal stamp across the center, depending on whether the goal is branding or an explicit warning.

Common use cases

Marking a document as "DRAFT" before internal review, stamping "CONFIDENTIAL" on a document ahead of sharing it outside your organization, adding a company logo to outgoing proposals, or watermarking a sample document to discourage unauthorized redistribution.
