About the Word Watermark Tool
The Word watermark tool adds a text or image watermark to a .docx file without ever uploading it. For a text watermark you pick the wording, color, size, and whether it should run diagonally across the page; for an image watermark you upload a picture that is automatically downscaled and lightened so it reads clearly behind your content. Behind the scenes the watermark is placed into the document headers — the same mechanism Microsoft Word uses — so it appears on every page of every section, including the first page when the document has a separate first-page header. Because everything happens locally, your documents stay private and there is no file size limit beyond what your browser can handle. Need to remove a watermark instead? Use the dedicated Remove Watermark from Word tool.
How to Add a Watermark to Word Documents
Watermarking a document takes three simple steps:
Upload a Document
Drag and drop or browse for the .docx file you want to watermark.
Choose Your Watermark
Pick text or image mode, then set the wording, color, size, orientation, and opacity.
Download the Result
Apply the watermark, then download each file individually or grab all of them as a ZIP archive.
Good to Know
Watermarks are written into the document headers the same way Microsoft Word does it, so they appear on every page and stay in place when you keep editing the file in Word, Google Docs, or LibreOffice. The image watermark is automatically lightened (its opacity controls how strong it looks) and resized to fit, so no extra image editing is needed. All processing is local: nothing is uploaded, and files of any size are supported.
