How to Get the Best Results from a Free Unrestricted AI Image Generator
Before you start creating, it’s worth knowing a few pro tips that can help you get the most out of any free unrestricted AI image generator. Whether you’re aiming for quick concept art or high-quality, commercial-ready images, these steps will help you work smarter and achieve better results:
Step 1. Write detailed prompts
Go beyond just naming the subject. Include style, lighting, color palette, composition, and fine details so the AI clearly understands your vision. The more specific you are, the more accurate and impressive your results will be. You can use structured prompts to get the best AI-generated results. A simple formula:
Subject + Style + Details + Mood + Lighting + Composition
Prompt Example: Ultra-realistic portrait of a 25-year-old woman, medium-length chestnut hair, soft brown eyes, natural makeup, wearing a white linen shirt, photographed in golden hour sunlight, shallow depth of field, 50mm lens, 8K resolution, photorealistic style, cinematic lighting, DSLR quality.
Step 2. Batch generate multiple images
Don’t rely on a single attempt. Produce several variations in one run to explore different interpretations, then select the versions that feel most polished or creatively aligned with your goals.
Step 3. Enhance with Aiarty Image Enhancer
Transform decent AI outputs into studio-quality visuals. Upscale up to 32K resolution, remove blur and noise, and restore missing textures or intricate details—making your images ready for professional, print, or large-scale display use.
Step 4. Save and export for final use
Expand Export Settings option to choose the output format (PNG, JPG), DPI, quality and folder path. Then tap "Single Export" or "Batch Export" to export your enhanced AIGC images. Keep your enhanced images in high-quality formats so they’re perfectly prepared for commercial licensing, crisp printing, or standout social media content.
Ethics & Legal Rules You Can’t Ignore When Using AI Image Generators
When creating and enhancing AI-generated images, it’s crucial to understand the ethical and legal responsibilities that come with using these powerful tools. Following best practices ensures your creations remain safe for commercial use and avoid potential copyright or regulatory issues.
