Frequently asked questions
How do I add a watermark to a PDF?
Type the watermark text you want, such as Confidential or Draft, adjust its position and opacity, and apply it across all pages at once.
Can I remove a watermark after adding it?
Not with this tool once you've downloaded the file, so keep an unwatermarked copy of your original PDF saved separately just in case.
Can I control the watermark's size and angle?
Yes, you can adjust the text size, rotation angle, and opacity before applying it across every page.
Can I use a password-protected PDF with this tool?
Yes — if the PDF is password-protected, you'll be prompted to enter its password before the watermark is applied; you don't need to unlock it in a separate tool first.
Does watermarking a PDF reduce its quality?
No, the watermark is drawn as an extra text layer, so the original page content stays untouched underneath it.
Is this watermarking tool free to use?
Yes, and there's no limit on pages or watermarks — everything processes locally, so your file is never uploaded.
