About this tool
Add a watermark to a PDF free, entirely in your browser — type text or upload a logo, set its position and opacity, and apply it across every page. Nothing is uploaded to a server; the watermarked PDF downloads straight from your device in moments.
Privacy & limitations
Background placement is best-effort: the watermark is appended to the page's existing content stream, so on a page that already has graphics, the stamp is drawn over them rather than literally underneath. Use foreground mode when the stamp must clearly sit on top. Text watermarks use the fourteen built-in PDF standard fonts only — custom or embedded fonts cannot be used, so exact brand typography is not possible. Watermarks are applied as flat drawings (vector text or the image XObject); they are not searchable/reflowable metadata, and the original content is not removed, so a watermark never truly hides underlying text.
