Free PDF Watermark — Add Text Watermark to PDF Online

October 12, 2026 · 3 min read · By the DollarWise team

How it works

Stamp “CONFIDENTIAL”, “DRAFT”, your name, or your business across every page of a PDF — without uploading the document to a server. Choose the text, how see-through it is, the size, color, angle, and whether it sits in the center, at the top or bottom, or tiled across the whole page. The watermark is drawn into the PDF itself with pdf-lib, right in your browser.

    Plain A–Z text works best — the built-in font covers Latin characters.
    Tiled repeats the text across the whole page — hardest to crop out.
    Lower = fainter stamp, higher = bolder stamp.
    Relative to the page — 36 pt reads well on A4 / Letter.
    Diagonal is the classic document-stamp look.
    Gray at low opacity stays readable without hiding the text under it.
    The name your watermarked PDF downloads with.

    Everyday uses

    • Drafts & proposals — stamp DRAFT or CONFIDENTIAL so nobody mistakes a work-in-progress for the final version.
    • Freelance previews — tile your name across design or document previews until the client pays.
    • Invoices & quotes — mark copies as PAID or COPY so originals stay distinguishable.
    • Shared handouts — put your business or class name on worksheets and guides you give away.

    Frequently asked questions

    Which characters can the watermark use? The stamp is drawn with a standard built-in font (Helvetica), which covers Latin letters, numbers, and common punctuation. Text in scripts like Arabic, Urdu, Chinese, or emoji may not render — keep watermarks to plain A–Z text for reliable results.

    Can the watermark be removed later? It’s drawn into each page as real content, so it can’t be switched off like a viewer overlay. Determined editors with full PDF software can sometimes alter page content, so treat a watermark as a strong deterrent, not copy protection — the tiled layout makes removal hardest.

    Does it stamp every page? Yes — every page of the document gets the watermark in the same position, size, and opacity, including pages of different sizes.
