How to Convert Your SVG Logo to Tiny PS Format for Use in Verified Mark Certificates

VMC is an emerging technology that enables you to authenticate your brand by displaying your registered logo alongside your outgoing emails. Recipients can see your brand logo, assuring them that it’s really from you, cultivating a more immersive email experience. 

SVG trademark images used in Verified Mark Certificate (VMC) must be in SVG Tiny Portable/Secure (SVG Tiny PS). Follow the steps below to convert your SVG image to this format. 


Step 1: Convert SVG trademark image to SVG 1.2 with square aspect ratio using Adobe Illustrator

Step 2: Convert SVG trademark image to Tiny PS format. 

Step 3: Verify trademark image


Step 1: Convert SVG trademark image to SVG 1.2 with square aspect ratio using Adobe Illustrator. 

Using Adobe Illustrator, you can convert your SVG 1.0 or 1.1 to SVG 1.2 format. To ensure that the trademark image has a square aspect ratio, the height/width of the SVG image (artboard in Illustrator) must be same. The following steps show how to achieve this in Illustrator. 

1. Select "Edit Artboards" in the "Properties" tab

edit artboard

2. Enter same Width (W) and Height (H) for the artboard and press enter.

Note: The image should also be centered horizontally and vertically. A little whitespace is recommended so that circular/elliptical clipping doesn't clip the logo. 


Saving the SVG image

1. Select File Save As
