Frequently asked questions

Is this PDF watermark tool free?
Yes, it's completely free with no account, sign-up, or watermark. Enter an email when you download and the file is yours.
Are my files uploaded anywhere?
No. All processing happens locally in your browser — your PDF is never uploaded to a server, so it stays completely private.
Can I use my company logo as the watermark?
Yes. Switch to Logo mode and upload a PNG or JPG — it's stamped onto every page at the size and opacity you choose.
Can I make the watermark faint or bold?
Yes. Use the opacity control for a subtle background mark or a strong, obvious stamp, and pick a diagonal, tiled, or footer layout.
