How to Add a Watermark to a PDF Online

Add text or image watermarks to PDF pages in your browser. Free, private, no upload — protect your documents.

Watermarking PDFs is essential for protecting intellectual property, marking documents as drafts, or branding reports before distribution. ConvertCraft makes it easy without any desktop software.

ConvertCraft's PDF Watermark tool adds text or image watermarks to every page of your PDF directly in your browser. Your document never leaves your device.

To add a watermark: open the PDF Watermark tool, upload your PDF, choose between text or image watermark, configure position, opacity, and rotation, then click Apply. The watermarked PDF downloads instantly.

Text watermarks support custom fonts, sizes, colors, and angles. Common presets include "CONFIDENTIAL", "DRAFT", and "SAMPLE" with diagonal positioning for maximum visibility.

Image watermarks let you overlay a company logo or stamp on every page. You can control opacity (typically 10-30% for subtle branding) and position (center, corner, or tiled across the page).

Frequently Asked Questions

Can I watermark specific pages only?

Yes. You can select which pages receive the watermark — all pages, odd/even pages, or a custom page range.

Will the watermark affect text selection?

The watermark is added as an overlay layer. Underlying text remains selectable and searchable in PDF readers.

Can I remove a watermark later?

ConvertCraft's watermark tool adds a permanent layer. Always keep an unwatermarked copy of your original document.
