Watermark PDF — FAQ
Is the PDF watermark tool free?
Yes — watermark as many PDFs as you like, free, with no signup. The tool never adds its own watermark. Pro adds batch processing and saved brand presets.
Are my PDFs uploaded?
No. The watermark is applied with pdf-lib directly in your browser, so your document never leaves your device.
Can I use my company logo?
Yes — choose “Logo / image”, upload a PNG or JPG, and set how big and how transparent it should be on each page.
Will it watermark every page?
Yes, the watermark is stamped on every page of the document in one click.
Can I remove a watermark from a PDF?
This tool adds watermarks. Removing one depends on how it was applied; for flattened watermarks it is often not possible, which is exactly why watermarking is useful for protecting drafts.
