Using Text in Images
Ads may not include images with text that covers more than 20% of the image's area.
In part, this is because using images with minimal text makes your content more engaging and helps to ensure that people only see high-quality content on Facebook and Instagram. This guideline applies to all ads, including video thumbnails.
You can use our grid tool to see if your ad images meet the requirement for this policy.
