How to watermark a PDF

How to use it in TooloraHUB

1. Open Watermark and upload the PDF file.
2. Enter the watermark text and adjust opacity or visibility settings as needed.
3. Run the tool and let TooloraHUB apply the watermark across the document.
4. Download the output and check the watermark is readable without blocking important content.

Supported inputs and outputs

• Input: A PDF file that needs a repeated visual label.
• Input: Short watermark text such as Draft, Internal, Review Copy, or Confidential.
• Output: A PDF with the watermark visible across pages.
• Output: A document that is easier to classify during review, sharing, or storage.

Tips and best practices

• Use concise text so the watermark stays readable at smaller scales.
• Test opacity carefully. Too dark can obscure content and too light can become meaningless.
• Apply the watermark to the final version of the document so page order and content are already stable.
• Combine watermarking with protection if the PDF also needs access controls.

Common problems and fixes
