About Watermark Excel

Add a watermark to Excel workbooks before they go to a supplier, an auditor or a client who should know the figures are confidential or still a draft. Excel has no watermark button, so the usual workaround is a picture in the page header, which shows only in Page Layout view and on paper. We do that on every sheet, and add a lighter copy behind the cells so it's visible while you work too. If the draft comes back with edits, Compare Excel points out every changed cell.

The header picture is centered and matches each sheet's orientation, so it appears on every printed page and in PDF exports. Choose the text, color and opacity; Chinese text is drawn with a Chinese font. An existing header picture or sheet background is replaced, while cells, formulas and charts aren't touched.

How to use Watermark Excel

    Type the watermark

    Enter the Watermark text, such as CONFIDENTIAL or your company name.

  3. 3
    Pick color and opacity

    The defaults are silver at 40% opacity. Lighter settings work best behind numbers.

  4. 4

    Every sheet gets the watermark, and the workbook downloads under its original name.

Why use Cubfile for this

  • Visible while you work

    A faint, tiled copy sits behind the cells as the sheet background.

  • Printed on every page

    A larger copy goes in the center of the page header, so paper copies and PDFs carry it.

  • Every sheet at once

    All sheets are marked, including ones with a different first page or separate odd and even headers.

  • Right way up

    Landscape sheets get a landscape watermark and portrait sheets a portrait one.

FAQ

Watermark Excel: questions and answers

Does the Excel watermark show when I print or save as PDF?
Yes. It's placed in the page header, which Excel prints on every page and includes in PDF exports. On screen, the lighter background copy shows behind the cells.
How do I add a watermark to Excel on a Mac?
The same way as on Windows. Upload the XLSX here, type the text and download the result. Nothing to install, and the page works in Safari. If the Mac has no Excel, open the result in Office Viewer to see it in the browser.
Can people remove the watermark?
Anyone who can edit the workbook can delete the header picture and background in Excel. If the mark must stay, share a PDF of the watermarked sheets instead.
Is it free to add a watermark to Excel sheets?
Yes, within the free limits of 2 tasks in total for visitors and 2 a day on a free account, for workbooks up to 50 MB. VIP removes the daily limit and accepts 1 GB files.
What happens to my workbook afterwards?
It's deleted from our server one hour after processing, along with the watermarked copy. The upload is encrypted, and nobody looks at your figures.
