Usage guide

How do I get started?

Choose your PDFs or drag them into the workspace. Enter watermark text, set its position and opacity, then check the preview. Check the preview and download the result to your device.

How do I select pages?

Select page cards or enter a range such as 1-3, 5. Numbers refer to the current workspace order. Check your selection and page order before downloading.

What does this operation change?

The watermark is overlaid while preserving original content. It does not prevent copying or securely remove sensitive information. Use permanent redaction to remove information.

What are the file limits?

Up to 10 PDFs, 20 MB per file, 50 MB total and 100 pages. Open password-protected files in your own PDF application first. Editing a signed document may invalidate its signature.

PRIVACY

Your file stays with you.

Images, PDFs and output files are processed on this device. We do not send filenames or file contents to a server, or save them in persistent browser storage.

Optional account, no tracking code

No account is required. The app has no advertising trackers or third-party analytics.

You’re in control

“Clear all” removes temporary file references. Downloads stay on your device. The browser and operating system manage their own temporary files outside the app’s control.

Connection logs are separate

The hosting provider may process connection details such as IP addresses for security and access. This does not promise complete internet anonymity; it describes how the app avoids storing user files.
