Stamp a diagonal text watermark such as DRAFT or CONFIDENTIAL across every page of a PDF. Processing stays in your browser.
This tool places a text watermark on every page of a PDF. Type the text you want (it starts as CONFIDENTIAL), and it is drawn in large bold red letters at 35 percent opacity, angled at 45 degrees across the middle of each page. The original content remains readable underneath.
The watermarked copy downloads with "watermarked-" added to the file name, and the work is done entirely in your browser. Typical uses include marking drafts, review copies, or internal documents before sharing them. Font, size, color, and position are fixed. The built-in font supports basic Latin characters, so text in other scripts or with emoji may fail. If several files are loaded, only the first is watermarked.
No. The watermark always uses semi-transparent red bold text at a 45-degree angle near the center of each page. Only the text can be changed.
It is drawn onto the pages as regular content, so it is not easily removed with ordinary viewers. Keep your original file if you need an unmarked copy.
The standard font only covers basic Latin characters. Text in other alphabets, special symbols, or emoji cannot be drawn.
