How to Add a Watermark to a PDF Online?
Protecting your intellectual property is essential when sharing documents online. Our tool allows you to stamp your PDF files with custom text watermarks across all pages instantly:
- Upload Document: Select or drag and drop your PDF into the upload zone.
- Customize Text: Enter your desired watermark text, such as "CONFIDENTIAL", "DRAFT", or your company name.
- Adjust Appearance: Select the text color and opacity (transparency) to ensure the watermark protects your content without making the original text unreadable.
- Generate: Click the button to instantly stamp your document and download the secured PDF.
Secure Client-Side Watermarking
Unlike other PDF tools that force you to upload your sensitive files to their cloud servers, Digital Dyno processes the watermarking directly within your web browser using JavaScript. This means your private proposals, legal drafts, and financial documents never leave your computer, ensuring absolute data security and zero latency.
Frequently Asked Questions (FAQs)
Where will the watermark be placed?
Our engine automatically calculates the exact center of each page and stamps your custom text diagonally across the document. This provides maximum coverage and security against unauthorized copying.
Can I remove the watermark later?
Once a PDF is watermarked and downloaded, the text is permanently embedded into the document's layout. We recommend always keeping a clean, un-watermarked backup of your original file.
