Frequently Asked Questions (FAQ)

Yes, most established tools like Adobe Firefly, DALL·E 3, and Canva explicitly allow commercial use in their terms. Always review each platform’s licensing policy before publishing client work.
Which free AI image generator is best for social media marketers?
Canva’s AI image generator is the most practical for U.S. marketers. Its ability to embed AI-generated visuals directly into social media templates makes it highly efficient.
What’s the biggest drawback of free AI image generators?
The main drawback is the limited number of free generations. Most platforms restrict usage, forcing heavy users to upgrade to paid tiers. Planning prompts ahead of time is the best workaround.
