Frequently asked questions

Answers about the workflow, file quality, and situations you may encounter.

Must a watermark be text?

Capable editors accept text or image watermarks. Supported image formats vary by application.

Can I apply it only to selected pages?

Tools with page-range controls let you choose the scope. Check its first and last applicable pages.

Is a watermark the same as a stamp?

Not necessarily. In Acrobat, a watermark is fixed page content, while a stamp can be an annotation.

How can I avoid an overpowering watermark?

Review opacity, size, and placement. A lighter background treatment may keep the document easier to read.

Does a watermark replace password protection or a signature?

No. A visible mark does not provide access control or certificate validation; those are separate security and signing operations.

Can I complete the operation and download a file on this page?

This version supports file selection and checks of file type, size, and count. Processing is not connected, so it does not convert, edit, or generate downloads. The guide describes a workflow in an application that supports the operation.

Which file types and sizes can I select?

This tool accepts PDF file extensions. You can select up to 20 files, with a 25 MB per-file limit and 100 MB total. Checking an extension does not verify that the file contents are valid or undamaged.

Are my selected files sent to a server?

In this version, file contents are not read or uploaded. Selections stay in the tab’s memory and are cleared on refresh. File names, extensions, and sizes are used only to display and check your selection.
