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.
