What is Watermark PDF used for?
Purpose
What does Watermark PDF do?
Use Watermark PDF to choose one PDF plus text or a logo, place, tile, rotate, and fade the watermark on chosen pages. Text and image watermarks are previewed with their real position and opacity before export. Filozy starts the document engine only after you choose a file, performs the work inside this tab, and creates a new result for you to save. Your selected document, its filename, and its contents are not sent to Filozy.
Who normally uses it?
This guide is useful for people adding visible information, branding, numbering, print layouts, or reusable page content. The working tool is focused on one outcome: Text or a logo — placed, tiled, angled, on the pages you pick.
Prepare
Before you start
- Plan the pages, position, text, color, and size before applying a repeated change.
- Keep important text inside a safe margin so printers and page crops do not hide it.
- Work on a copy when the output will make comments, fields, or additions permanent.

Better results
Practical tips for Watermark PDF
Use the page preview at a larger zoom for precise placement.
Keep typography, spacing, color, and position consistent across repeated pages.
Open the exported PDF and inspect the first, middle, and last affected pages.
Honest expectations
Limitations and important checks
The result depends on the structure and quality of the source document, so visually inspect the exported file before relying on it.
Browser memory varies by device. Very large or unusually complex PDFs may work better when processed in smaller groups.
Questions and answers
Watermark PDF FAQ
Direct answers to the questions people commonly ask before using this tool.
What is Watermark PDF used for?
Watermark PDF is a browser-based Filozy tool built for this task: Text or a logo — placed, tiled, angled, on the pages you pick. It runs on this device, creates a separate result, and does not require an account or document upload.
Can I use Watermark PDF on a phone or tablet?
Yes. Watermark PDF works in a current mobile browser. Complex PDFs can need more memory, so keep the tab open, avoid switching apps during processing, and inspect the result before closing the page.
Does Watermark PDF upload my file?
No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.
Will this change my original file?
No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
What should I check after using Watermark PDF?
Check the visible preview and the result summary. Text and image watermarks are previewed with their real position and opacity before export. Keep the original until the new output has been opened and verified.
Do I need an account or subscription?
No account is required for this browser-side tool. It runs on the device and does not use a document-upload allowance or daily server quota.
Privacy
Where does my document go?
For this tool, the document stays in the browser tab. Filozy can load same-origin support files such as its PDF engine, fonts, or OCR data, but the selected document bytes and filename are not sent with those requests.
