03 · WHAT YOU GET
A watermark that fits the page.
Every feature below runs on your device. See how the engines work.
Real fonts, many scripts
Accented Latin, Chinese and Tamil are shaped with embedded Noto fonts; the text stays searchable.
Three strengths
Subtle for a light background mark, Medium for everyday drafts, Strong for clear warnings.
Original content untouched
The watermark is added as a new layer; pages, forms and links remain as they were.
Can I use an image or logo as the watermark?
Not yet. This tool stamps text only.
Can the watermark be removed later?
It is drawn into the page content like any other text, so removing it requires a PDF editor. Keep your original if you need an unmarked copy.
Which characters are supported?
Latin scripts with accents, Chinese, Tamil and single emoji. Right-to-left scripts and combined emoji sequences are rejected with a message rather than rendered incorrectly.
