Frequently asked questions

What is a PDF watermark?▾

A watermark is a semi-transparent label placed on every page of a PDF, usually text such as DRAFT, CONFIDENTIAL, or SAMPLE, or a faint company logo. It signals the status or ownership of a document at a glance, without anyone needing to read a cover note first. Law firms watermark draft contracts so nobody mistakes them for the signed final version. Design agencies watermark proofs before a client has paid, so the images cannot be used commercially yet. Photographers watermark previews before a client selects and pays for full-resolution copies, and real estate agents put a small logo watermark on floor plan PDFs shared with prospective buyers. Because the watermark sits on top of the existing page content, the underlying document is unchanged underneath it.

Who uses PDF watermarks?▾

Lawyers marking drafts, designers sharing proofs, HR teams labeling internal documents, and small businesses putting a logo on client-facing PDFs before final approval.

Can I use a logo as a watermark?▾

Yes. Switch to image watermark and upload a PNG or JPG. Drag it on the page-1 preview to place it; the same relative placement applies to every page.

Is this a security watermark?▾

No. This adds a visible overlay only. It does not stop copying, editing, or password protection by itself. Use it for clarity and branding, not as DRM.

Can I watermark with custom text?▾

Yes. Choose text watermark and type your label, for example SAMPLE or your company name. Drag to place it, then set size, rotation, and opacity.

Is my file private?▾

Yes. Watermarking runs locally in your browser. Your PDF and logo image are not uploaded to Justools servers.

What are the limits?▾

One PDF up to 25 MB per job. Image watermarks accept PNG or JPG files.
