Add a Logo Watermark to PDF — Free Online Tool
Overview
Adding your company logo as a watermark to proposals, reports, and presentations protects your brand and marks documents as proprietary. PDF Mavericks supports image watermarks — upload a PNG with a transparent background, set the opacity between 10% and 100%, choose the position, and apply it to every page or a page range.
How to Use This Tool
Go to the Watermark page and upload your PDF. Select 'Image Watermark' and upload your logo as a PNG file. A transparent-background PNG works best so the watermark doesn't create a solid box over your content. Set the opacity (20-40% is typical for subtle branding), choose a position (center, top-right, bottom-left), and click Apply. Download the watermarked PDF.

Add Watermark →Frequently Asked Questions
What image formats work for logo watermarks?
PNG is the best format — especially PNG with a transparent background. This prevents the watermark from appearing as a solid white rectangle over your content.
Can I apply the logo watermark to all pages at once?
Yes. The watermark is applied to every page in the document by default. You can also target specific pages if needed.
How transparent should my logo watermark be?
For background branding, 15-30% opacity keeps the logo visible without obscuring content. For prominent ownership marks, 50-60% opacity is more assertive.
