Protect Your Documents with Text Watermarks
Adding watermarks to PDF documents helps protect intellectual property, clearly mark document status (DRAFT, CONFIDENTIAL, DO NOT COPY), and prevent unauthorised distribution. Watermarks are used by lawyers on draft contracts, companies on confidential reports, photographers on sample images and publishers on advance copies. Our tool adds customisable text watermarks to every page with control over size, opacity, position and color.
Frequently Asked Questions
How to add watermark to PDF online free without Adobe? ▼
Upload your PDF, type your watermark text (e.g., CONFIDENTIAL, DRAFT), choose size (60pt recommended), set opacity (0.15–0.25 for subtle, 0.5 for prominent) and position (center diagonal is standard). Click Add Watermark — done in seconds.
How to make a watermark transparent on PDF? ▼
Set the Opacity value to 0.1–0.2 for a very light watermark that is visible but does not obstruct reading. Our tool lets you set exact opacity in increments of 0.05.
What is the standard watermark for confidential documents? ▼
The most common watermarks are: CONFIDENTIAL, DRAFT, DO NOT COPY, FOR REVIEW ONLY, INTERNAL USE ONLY and PRIVATE. Use red color for CONFIDENTIAL, gray for DRAFT. Center diagonal placement at 45° is the professional standard.
Can a watermark be removed from a PDF? ▼
Watermarks added as text overlays (like ours) can be removed with advanced PDF editing software. For higher protection, use a more opaque watermark. True tamper-proof watermarking requires special digital watermarking technology beyond text overlays.
