Key features
- Single mode stamps once via a 9-position grid; Tiled mode repeats the text across each page.
- Font size 24–200 pt, opacity 5–100%, rotation −90° to +90° and any color.
- Tile spacing is adjustable (120–600 pt) for full-page coverage in Tiled mode.
- Mixed page sizes are handled — each page is stamped relative to its own dimensions.
- Exports as yourname-watermarked.pdf with a re-download button; open-password files are refused up front.

Tips for better results
- Keep opacity between 10% and 20% so the underlying text stays readable.
- Tiled mode at about −45° rotation is the classic draft-document look.
- Stick to plain Latin letters, numbers and punctuation — the built-in font cannot encode emoji or CJK characters.
