You can add a transparent stamp to any PDF by placing a PNG image with a transparent background right where you need it.
A transparent stamp helps you brand files, mark approvals, or add signatures without covering the content. You can place a logo or a signature as a clear overlay that blends into the page.
We’ll use Edit PDF for image stamps and Sign PDF for signature stamps, so you get clean, professional results every time.

Step 1: Open Edit PDF
Open Edit PDF. The editor lets you add text, images, comments, and more directly in your browser.
Step 2: Upload Your File
