Why Add Watermarks to PDFs?
Watermarks protect your documents, indicate their status, and reinforce branding. From draft markers to copyright notices, watermarks communicate important information about your documents.
Common Watermark Uses
- DRAFT / CONFIDENTIAL: Mark documents that shouldn't be shared or are works in progress.
- Company Branding: Add your logo or company name to official documents.
- Copyright Protection: Discourage unauthorized use of creative work.
- Document Status: Mark as COPY, SAMPLE, VOID, or APPROVED.
Watermark Best Practices
Use diagonal placement for maximum visibility. Keep opacity low (20-40%) for background watermarks, higher (60-80%) for prominent status markers. Choose colors that contrast with your document content.
자주 묻는 질문
Can I customize the watermark?
Yes, you can customize the text, position (center, corners, edges), font size, opacity, color, and rotation angle.
Will the watermark appear on all pages?
Yes, the watermark is applied consistently to all pages of your PDF for complete document protection.
Is adding watermarks to PDFs free?
Yes, our watermark tool is completely free with no registration, file limits, or hidden costs.
Can I add an image watermark instead of text?
Currently, our tool supports text watermarks with full customization options. For image watermarks, consider using our Edit PDF tool.
Can I remove a watermark after adding it?
Once downloaded, the watermark is permanently embedded. Always keep your original unwatermarked file as a backup.
What's a good opacity setting for watermarks?
For subtle branding, use 10-30% opacity. For visible copyright notices, 30-50% works well. For draft stamps, 50-70% ensures clear visibility.
Can I add a diagonal 'CONFIDENTIAL' watermark?
Yes, you can add any text and rotate it diagonally (typically 45°). Common watermarks include CONFIDENTIAL, DRAFT, COPY, and company names.
Will the watermark affect text readability?
Low-opacity watermarks (10-30%) overlay content without significantly affecting readability. Adjust opacity to balance visibility and legibility.
Can I preview the watermark before applying?
Yes, you can preview how your watermark will look on the document before finalizing and downloading.
Does watermarking affect file size?
Text watermarks add minimal file size (typically less than 1KB). The impact on overall PDF size is negligible.
