Quick Answer

Add Watermark places custom text on every page of your PDF. Enter your watermark text (like "CONFIDENTIAL" or your company name), choose position and opacity, and download. Processing happens locally in your browser—nothing is sent to a server.

Why Add Watermarks?

Watermarks communicate something important about your document before anyone reads a single word.

They serve three key purposes:

Status indication. Is this a draft or final version? A sample or the paid product? A working copy or the approved release? Watermarks answer these questions at a glance, preventing confusion and misuse.

Protection. "CONFIDENTIAL" watermarks remind recipients they're handling sensitive material. They don't prevent copying, but they establish clear expectations and create a paper trail if documents are mishandled.

Branding. Your company name on every page reinforces ownership and origin. When documents get forwarded or printed, your brand travels with them.

📋 Classic Scenario: The Draft That Got Shared

You send a draft proposal to a colleague for review. They forward it to the client "for early feedback." Now the client has seen incomplete work without context. A "DRAFT - NOT FINAL" watermark would have prevented confusion and set proper expectations.

Types of Watermarks

Watermarks fall into two main categories based on their purpose.

Status Watermarks
Communicate document state
  • DRAFT
  • CONFIDENTIAL
  • FOR REVIEW ONLY
  • SAMPLE
  • DO NOT DISTRIBUTE
  • INTERNAL USE ONLY
  • APPROVED
  • VOID
Branding Watermarks
Establish ownership and origin
  • Company name
  • © Copyright notices
  • Website URL
  • Department name
  • Project identifier
  • Author name
  • License terms
  • Version numbers
💡

Combine both types when needed. A document might carry both "© Acme Corp 2024" for branding and "CONFIDENTIAL" for status. Run the tool twice with different watermarks, or combine them into one text string.

Position Options

Where you place the watermark affects both visibility and document usability.

Diagonal Center Most Common
Runs across the page from corner to corner. Maximum visibility, impossible to crop out. Best for "DRAFT" and "CONFIDENTIAL."
Top Left
Subtle placement in the corner. Good for branding that shouldn't distract from content.
Top Right
Common for copyright notices and version numbers. Visible but not intrusive.
Bottom Left
Often used with page numbers. Less visible in normal reading.
Bottom Right
Standard location for copyright and attribution. Least intrusive position.

Choosing the Right Position

Use diagonal center when the watermark's message is critical (drafts, confidential documents, samples). Use corner positions when you want branding present but not distracting from the content. The more important the watermark message, the more prominent the position should be.

Opacity Settings

Opacity controls how visible your watermark is. Too light and it's missed; too dark and it blocks content.

20-30%
Subtle
Faint background presence. Good for branding watermarks that shouldn't distract.
Recommended
40-50%
Balanced
Visible but readable. Best for most use cases including DRAFT and CONFIDENTIAL.
60-70%
Prominent
Unmissable. Use for VOID or when document should clearly not be used as-is.

⚠️ Test Before Sending

What looks right on screen may print differently. If your watermarked document will be printed, test the opacity on paper before distributing. Screen brightness varies, but paper is consistent.

Frequently Asked Questions

Will the watermark appear on all pages?
Yes. The watermark is applied to every page of your PDF automatically. There's no option to watermark only specific pages—if you need that, use Split PDF first, watermark the relevant pages, then Combine Files to recombine.
Can the watermark be removed?
Watermarks added as text overlays can potentially be removed with advanced PDF editing software. If you need tamper-proof watermarks, consider using Flatten PDF after adding the watermark—this permanently bakes the watermark into the page content.
What opacity should I use?
40-50% works well for most cases—visible but not obstructive. Use lower opacity (20-30%) for subtle branding. Use higher opacity (60-70%) for "VOID" or documents that should clearly not be used as-is.
Can I add an image as a watermark?
This tool supports text watermarks only. For image watermarks (like logos), you'd need a desktop PDF editor like Adobe Acrobat or similar software.
Is Add Watermark free?
Yes. Guest users get 2 free uses per day. Free accounts (email signup, no credit card) get 5 daily. Pro subscribers get unlimited access to all 18 PDF tools.
Is my file sent to a server?
No. All processing happens locally in your browser. Your document never leaves your device. We can't see what you're watermarking because the data never reaches us.
Can I add multiple watermarks?
You can run the tool multiple times on the same document. First add "CONFIDENTIAL," then run it again to add your company name in a different position. Or combine both into one text string like "CONFIDENTIAL - Acme Corp."
Does the watermark affect file size?
Minimally. Text watermarks add very little to file size—typically just a few kilobytes regardless of how many pages your document has.
