Common questions about watermarking
How do I add a watermark to a PDF online?+
Drop your PDF, type the watermark text (e.g. CONFIDENTIAL), tweak the opacity and rotation in the live preview, then click Apply. The watermarked PDF downloads instantly.
Can I watermark every page at once?+
The watermark is applied to every page in the PDF in one pass.
Does the watermark stay in the saved file?+
Yes. The watermark is drawn into the page content, so it travels with the file. To remove it later, use our Edit PDF tool (though we'd recommend keeping the original).
Is the watermark tool really free?+
The watermark tool is free to use, with no signup and no per-page fee. FileHook never stamps its own logo on your exports, even on the free plan; the only watermark on the file is the one you added.
