Text watermarks communicate status at a glance: DRAFT, CONFIDENTIAL, DO NOT COPY. CrispPDF's Text Watermark tool stamps your message across every page with full control over font, color, opacity, and angle.
Type your text, position it diagonally or horizontally, set transparency to 10 % for subtle or 50 % for bold, and download. Apply to one page, selected pages, or the entire document.
For legal teams circulating preliminary drafts, a clear "DRAFT" stamp prevents accidental reliance on non-final text. For HR departments sharing internal memos, "CONFIDENTIAL" deters leaks.
Because processing happens in your browser, sensitive documents stay private. After watermarking, flatten the PDF to lock changes permanently or password-protect before sending.
