For text: enter your text (e.g., "CONFIDENTIAL", "DRAFT") and set the font size. For image: upload your logo or image. Then adjust opacity and choose the desired position (center, diagonal, corners, etc.).
Once all settings are configured, click the "Add Watermark to PDF" button to start processing.
Our servers will apply the watermark to every page of your PDF. The progress bar shows real-time status. Larger files may take a few moments longer.
When complete, download your watermarked PDF file. Files are automatically deleted from our servers after download for your privacy.
