Microsoft Designer is a new feature integrated into LinkedIn Ads that allows users to generate ad creatives tailored to their needs. It offers the ability to either create new designs from scratch or enhance and modify existing designs.

To use Microsoft Designer for ad creation in LinkedIn, follow these steps:

1. Create a new ad: Start by creating a new ad in LinkedIn Ads.
2. Choose your method: You can either upload an image as usual or select Microsoft Designer to generate the perfect ad creative.
3. Enhance existing designs: If you have an existing design, you can upload it to Microsoft Designer and ask the tool to enhance or modify it.

While Microsoft Designer offers a convenient and automated way to create and enhance ad creatives, some users might still prefer the touch of a human designer. This preference could be due to the unique creativity, personalized touch, and nuanced understanding that human designers bring to the table, which might not be fully replicated by AI tools.
