What it solves
A clear label on every page that needs one.
This tool stamps a text watermark across the rendered pages with full control: the wording — DRAFT, CONFIDENTIAL, a client name or your brand — plus angle, opacity, size, color and the page range that should carry it. The live preview shows exactly how the diagonal sits over the content before you commit, so the mark stays readable without drowning the page.
A text watermark deters casual reuse, but a determined editor can remove it. It labels the copy; it does not protect it — for real access control, encrypt the file with Protect PDF.
Common uses
Number an assembled pack
Give a merged proposal or dossier stable page references before printing or sharing it.

Quick instructions
Place the elements, check the preview, export.
- 01Open the PDF; every page is rendered locally in your browser.
- 02Add and configure the elements for the task — position, size, color, format or angle depending on the tool.
- 03Check the live preview on the real rendered pages before committing to anything.
- 04Apply the change; a new copy is built entirely on this device.
- 05Download the exported copy and verify it before sharing.
Limits worth knowing
Honest before the export.
- 01
Elements are placed on top of the existing pages. The text already embedded in the PDF is not rewritten or deleted — to remove content permanently, use Redact PDF.
- 02
A text watermark deters casual reuse, but a determined editor can remove it. It is labelling, not protection — for real access control, encrypt with Protect PDF.
- 03
Every operation creates a new download; the source file on the device is never overwritten.
- 04
Very large or image-heavy files are limited by the memory and processing power of the current device.
Frequently asked questions
Watermarking a PDF — FAQ.
01Does this tool upload my PDF?
No. The document bytes stay in the browser and all processing runs on this device. Nothing is sent to any server.
02Can it change or delete the text already inside the PDF?
No. These tools add new elements on top of the pages; the embedded source text is left untouched. To remove existing content irreversibly, use Redact PDF.
03Does a watermark protect my document?
Only against casual reuse. A text watermark is visible labelling that a determined editor can strip out. If you need to control access, encrypt the file with Protect PDF.
04Are there PDFs these tools cannot process?
Yes. A damaged file, unsupported encryption or a huge scan can require desktop software. The tool reports the failure instead of inventing a result.
