Gemini: best free AI image generator
Google’s free Gemini plan includes image generation and editing, according to Google’s Gemini subscriptions page. You can describe a new image or upload a photo and ask Gemini to change it, such as replacing the background or changing the style. The free plan also includes limited access to Google Flow with the Nano Banana Pro image model, and paid Google AI plans raise the limits.
Images made with Google’s AI tools carry an invisible SynthID watermark, which is useful for transparency. Learn more in our guide on how to tell if an image is AI-generated.
ChatGPT: best for creating images in a conversation
ChatGPT lets you create and refine images by chatting, which makes it easy to adjust details step by step: “make the background lighter”, “add a coffee cup on the table”. According to OpenAI’s pricing page, the free plan includes limited image creation, and paid plans add more. If you already use ChatGPT for writing, it is convenient to make matching images in the same place. See our guide to GPT-6 in ChatGPT for what the latest version adds.
Adobe Firefly: best for commercial use
Adobe says outputs from its own Firefly AI models are safe for commercial use, which matters if you sell products or run ads. The free plan includes daily generations across image, video and audio, with access to models such as Nano Banana. Paid plans start at $9.99 a month for 2,000 generative credits (Firefly Standard), and Firefly Pro costs $19.99 a month for 4,000 credits.
Adobe notes that you are responsible for checking whether content from partner models suits your project, so use Adobe’s own Firefly models when commercial safety matters most.
Midjourney: best for artistic images
Midjourney is known for detailed, artistic images and strong styles. Its plans start with Basic at $10 a month with about 3.3 hours of fast generation time, and Standard at $30 a month adds unlimited images in relaxed mode. Midjourney’s documentation does not list a free plan. Companies with more than $1 million in yearly revenue must buy the Pro or Mega plan.
Canva AI: best for marketing designs
Canva combines AI image generation with ready-made templates for social posts, flyers and ads. The free plan includes AI design and image generation with up to 20 uses, and Canva Pro at $144 a year adds background removal and more AI uses. It is the fastest path from an AI image to a finished post. See more business picks in our list of the best AI tools for small business.
Microsoft Copilot: best free option on Windows
Microsoft’s free Copilot includes image creation and works in Windows, the Edge sidebar and the Copilot apps. It is handy for a quick illustration or idea sketch. Microsoft 365 Premium adds higher limits and Microsoft Designer.
How do you write better prompts for AI images?
- Describe the subject first: “a ceramic coffee cup on a wooden table”.
- Add style and mood: “soft morning light, minimal, warm colors”.
- Say the format: “square image for Instagram” or “wide banner, 16:9”.
- Name what to avoid: “no text, no people”.
- Refine step by step: change one thing at a time instead of rewriting the whole prompt.
Our guide on how to write better AI prompts explains the same framework for text.
How do you prepare AI images for your website?
AI images are often large PNG files that slow down web pages. Convert them to WebP and compress them with our free Image Toolkit, which works in your browser. To pick the right format, read WebP vs AVIF vs JPEG vs PNG and our guide on compressing images without losing quality.
What should you know before using AI images?
- Check the license: commercial use rules differ by tool and plan, as the Midjourney and Firefly terms above show.
- Label realistic AI images where platforms ask you to, and never present them as real photos of real events.
- Avoid real people’s faces and brand logos unless you have permission.
- Keep private photos private: review each tool’s privacy settings before uploading personal images.
Before posting an AI image, resize it to the right shape for each platform. Our social media image sizes guide lists every size for 2026.
