Why do AI-generated images look bad sometimes?

AI images often look bad because the prompt lacks a clear, intentional structure. When key details are missing, the model has to guess, which usually leads to generic or inconsistent outputs.

Common issues include:

Missing details about style, lighting, or composition
No negative prompts, which allows unwanted artifacts (e.g. distortions, visual noise, anatomical errors)
Lack of iteration, where prompts aren’t refined after the first result

In most cases, improving prompt structure and making small, step-by-step adjustments leads to noticeably better results.

If you want to experiment, try adjusting your AI image prompts in Quillbot’s AI Image Generator and see how each small change affects the final result.

What size is a hero image?: A full-screen hero image is typically sized at 1280 × 720 pixels with a 16:9 aspect ratio, ensuring clarity on most screens. However, depending on your site’s design and target devices, you might opt for larger dimensions, such as 1600 × 900 pixels or 1920 × 1080 pixels, to maintain image quality on high-resolution displays.

Always test your image across various devices to ensure it loads quickly and appears sharp. You can use Quillbot’s AI Image Generator to create high-quality visuals that fit your design, then adjust them as needed.
Should AI image prompts be written in full sentences?: No, AI image prompts do not need to be written in full sentences. Image generators don’t interpret language like conversational chatbots; they respond better to keywords and short descriptive phrases.

Full sentences often add non-essential framing words like “a picture of” or “with a,” which can dilute the key visual instructions.

For more consistent results, use structured, comma-separated phrases that focus only on the visual elements you want. For example, “woman in a café reading a book, soft natural light, cozy atmosphere, cinematic style.”

If you’re unsure how to structure your prompt, Quillbot’s AI Image Prompt Generator can help you quickly brainstorm more detailed starting points.
