What Watermark PDF does

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.

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.

How to watermark pdf in your browser

1. Choose one PDF plus text or a logoSelect one PDF plus text or a logo from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
2. Review the settingsUse the page preview and available options to decide exactly how watermark pdf should handle this document.
3. Create and check the resultRun the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.

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.

Limits worth knowing

• 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.
