Watermarking PDFs — FAQ

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?+

Yes — 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 really free?+

Yes. No watermark on the watermark tool — and no signup, no per-page fee.
