Add PDF Watermarks Without Uploading Your Document

Watermarking a PDF often means sending it to a third-party server, which defeats the entire purpose if the document is confidential. OfflinePDF burns text directly onto your PDF pages using your browser — no upload, no third party, no exposure.

✍️ Custom Text
Type anything — CONFIDENTIAL, DRAFT, your company name, a watermark date.
🎨 Full Styling
Control font size, opacity, angle, and position. Make it subtle or unmissable.
📑 All Pages or Specific
Apply to every page, just odd/even pages, or a specific range.
🔐 Zero Upload
The watermark is rendered locally. Your content never travels to a server.
