WATERMARK STYLES // POPULAR APPLICATIONS
Branding, Copyright & Confidentiality Stamping
Add clear ownership marks or legal stamps without blocking readability:
| WATERMARK TYPE | TYPICAL TEXT / ASSET | RECOMMENDED OPACITY | BEST USE CASE |
|---|---|---|---|
| Confidential Notice | "CONFIDENTIAL", "DO NOT SHARE" | 15% – 25% (Light gray/red) | Financial reports, merger terms, internal staff documents |
| Draft / Revision Stamp | "DRAFT", "FOR REVIEW ONLY" | 20% – 30% (Diagonal center) | Contract drafts, architectural proposals, school essays |
| Company Logo & Brand | Transparent PNG company emblem | 20% – 40% (Corner or center) | Customer proposals, marketing handouts, invoices |
| Full-Page Tiled Mesh | Repeated company name or client name | 10% – 15% (Subtle repeat) | Preventing unauthorized redistribution or screenshot leaks |
PERFECT OPACITY // CLEAR TEXT
Readable Text with Subtle Blending
You can set transparency from 5% to 100%. The watermark floats cleanly over or behind the page without making the text underneath hard to read or printing as a dark, muddy blotch.
ZERO QUALITY LOSS // PRIVATE & FAST
Vector Sharpness with Automatic Cleanup
Text watermarks remain crisp vector fonts at any zoom level, while original document graphics retain 100% resolution. Files are transferred securely over SSL and permanently erased shortly after download.
Frequently Asked Questions
Q.01Does adding a watermark degrade existing text or image quality in the PDF?
No. Watermarks are added as clean visual layers without recompressing your images or blurring text. All original paragraphs, vector drawings, and photos remain in their native high resolution.
Q.02How do I make sure the watermark doesn't hide the text underneath?
You can adjust the opacity slider between 10% and 30%. This makes the watermark translucent, so it is clearly visible as an ownership or confidential stamp while allowing the text beneath it to remain completely legible.
Q.03Can I apply different watermarks or target only certain pages?
Yes! FILPDF gives you full page control. You can apply the watermark to all pages, the first page only, odd or even pages, or specify custom page ranges (like 1-5, 8).
Q.04Can I use my company's PNG logo image as a watermark?
Yes! Switch the watermark type from "Text" to "Image" and upload your transparent PNG or JPG logo. You can scale, rotate, position, and adjust the transparency of your image watermark easily.
