Frequently asked questions
Is this watermark tool free to use?
Yes, adding a watermark to your PDF is completely free with no sign-up, no usage limits, and no extra branding forced onto your file. Use it as often as you need.
Are my uploaded files kept private?
Your PDF is uploaded to a secure server over an encrypted connection, watermarked, and returned to you. Files are processed automatically and not shared with anyone.
Can I customize the watermark text and appearance?
