PDF Watermark, Stamp & Page Numbering

Yes. Switch to the "Stamp" tab to apply legal, double-bordered rubber stamps such as APPROVED, CONFIDENTIAL, REJECTED, PAID, or VERIFIED. You can customize the primary label, audit date/signature line, tilt angle, ink color, and place the stamp in any corner or the center of pages.

In the "Page #" tab, enable page numbering and choose your preferred format like "Page {n} of {total}" or "{n} / {total}". You can place page numbers across 6 standard positions (bottom-center, bottom-right, etc.), customize margins and font sizes, and toggle "Skip First Page" so cover pages remain unnumbered.

Yes. Toggle "Tiled 3x3 Grid Pattern" under watermark settings. Instead of a single centered watermark, your text will be repeated across a 3x3 grid on each page to protect intellectual property and prevent unauthorized copying.

No. All PDF loading, canvas rendering, text stamping, and document generation run 100% locally inside your web browser using WebAssembly and PDF-Lib. Your confidential agreements, financial records, and private documents never leave your computer.
