    Frequently asked questions

    What does the watermark look like?

    Your text is placed diagonally across the middle of every page, semi-transparent so the page stays readable.

    Can I change how faint it is?

    Yes. Use the opacity box, a smaller number is fainter (for example 0.25).

    Is my file uploaded?

    No. The watermark is added in your browser.
