Branding PDFs with a transparent logo watermark identifies them as official company documents. Here is how to add one for free.
For best results, use a PNG with transparent background. A transparent PNG logo blends cleanly with the page background at any opacity setting.
Navigate to the watermark tool. Switch to Image mode. Upload your PNG logo.
Set opacity to 15–25% for a subtle background watermark. Set size relative to page width. Center the logo or place it in a corner based on your branding preference.
Tip: For document control (preventing unauthorized copies), use center placement at 20% opacity. For branding without obscuring content, use corner placement at 60% opacity.
15–25% for center placement (subtle background). 50–70% for corner placement (visible branding). Avoid 100% opacity unless intentional.
