Common watermark uses
Watermarks are used to label draft documents before review, mark confidential files before distribution, indicate that a copy is for internal use only, stamp proofs and mockups before client approval, and add brand marks to documents shared outside an organization.
Text or logo?
Use text mode for clear status labels like DRAFT, CONFIDENTIAL, FOR REVIEW ONLY, or SAMPLE. Use image/logo mode when you want brand presence — a semi-transparent company logo centered on each page that is visible without obscuring the content.
Watermark FAQ
Can I add DRAFT or CONFIDENTIAL text? Yes. Text mode places the label you enter diagonally across every page. Common labels include DRAFT, CONFIDENTIAL, FOR REVIEW ONLY, SAMPLE, and NOT FOR DISTRIBUTION.
Can I use a transparent logo? Yes. PNG files with transparency work best — they let the page content show through while the logo is visible at reduced opacity.
Does the preview match the export? The live preview shows the watermark placement, size, angle, and opacity before you export. Use it to check readability — if the content underneath is hard to read, reduce opacity.
Is the watermark permanent? The watermark is embedded into the page content using pdf-lib, not placed as a separate removable layer. It is significantly harder to strip than a simple overlay, though no watermark is completely tamper-proof with determined effort.
Is my file uploaded when I watermark it? No. The watermark tool runs entirely in your browser. Your PDF is never sent to a server.
What opacity setting works best? For most text-heavy documents, an opacity of 15–25% keeps the watermark clearly visible without making the underlying content hard to read. For image-heavy documents, slightly higher opacity may be needed.
Can I remove a watermark from a PDF? No — this tool adds watermarks, it does not remove them. Watermarks embedded into page content are not stored as a separate layer, so removing one from an existing PDF typically requires dedicated desktop software.
